3Chi vs Delta Effex vs Mellow Fellow: Which Cannabinoid Brand Is Best?

Quick Answer: When comparing 3Chi vs Delta Effex vs Mellow Fellow, Mellow Fellow stands out as the strongest overall choice. Its pharmacist-formulated, mood-specific blends set it apart from brands that focus primarily on single cannabinoids or raw potency. With the widest product range – spanning disposable vapes, vape cartridges, edibles, drinks, flower, concentrates, and wellness – Mellow Fellow delivers targeted effects, full COA transparency, and a user experience built around how you actually want to feel.

Looking for the best legal hemp THC brand? The market is packed with options, but 3Chi, Delta Effex (now rebranded as Delta Extrax), and Mellow Fellow consistently land at the top of conversations about quality, selection, and consistency. Each takes a different approach – and that difference matters when you’re choosing where to spend your money.

3Chi built its name as one of the original Delta 8 brands, earning trust through early innovation and a broad cannabinoid catalog. Delta Effex (Delta Extrax) came up fast as a product of Savage Enterprises, making a name for high-potency, multi-cannabinoid blends and aggressive innovation in novel compounds. Mellow Fellow took a different path entirely: instead of chasing compound novelty for its own sake, the brand built its identity around pharmacist-formulated, mood-specific blends designed to deliver a precise and repeatable experience.

This guide breaks down every major category – product selection, quality and testing, brand reputation, pricing, and consumer experience – so you can make a clear-eyed decision about which brand is the best fit for you.

Key Takeaways

• 3Chi is one of the original Delta 8 brands, known for an extensive cannabinoid catalog and trusted COA transparency.

• Lab testing across all three brands includes third-party COAs, but Mellow Fellow makes results directly accessible on every product page.
• THCp binds to CB1 receptors with roughly 33 times the affinity of Delta 9 THC in vitro, making the cannabinoids inside formulated blends a meaningful differentiator between brands.
• Mellow Fellow’s product catalog is the most varied of the three, covering every consumption format from disposable vapes to THCa flower and hemp drinks.
• For buyers who want a curated experience with clear mood targeting and scientific formulation, Mellow Fellow is the clearest choice.

3Chi vs Delta Effex vs Mellow Fellow at a Glance

Mellow Fellow Overview

Mellow Fellow is not trying to win by offering the longest list of cannabinoids. The brand wins by making every product feel intentional. Rooted in pharmacist-formulated blends, Mellow Fellow designs its lineup around moods and real-life use cases: focus at work, creativity on a project, sleep after a long day, recovery after a workout, euphoria for social settings.

That approach makes product selection feel simple rather than overwhelming. Instead of sorting through dozens of single-noid SKUs, customers shop by how they want to feel. It’s a fundamentally different consumer experience from what 3Chi and Delta Effex offer – and it has earned Mellow Fellow a growing reputation as a brand that treats cannabinoids as a science rather than a commodity.

Every Mellow Fellow product is backed by third-party lab testing, with COAs accessible directly on each product page. The brand uses a wide cannabinoid toolkit – Delta 8, Delta 9, THCp, THCh, THCm, THCb, CBD, CBG, CBN, and CBC – combined with terpene-specific profiles to hit the intended mood with precision. The result is a catalog that spans more formats than any brand in this comparison.

 

 

 

Mellow Fellow Core Features

Pharmacist-Formulated Mood Blends

The clearest differentiator for Mellow Fellow is its approach to formulation. Rather than offering straight cannabinoid distillates or generic strain-named vapes, the brand builds multi-compound blends around a specific mood or effect goal. Each blend pairs cannabinoids with complementary terpenes to produce a consistent, repeatable result.

The current mood blend lineup includes:

• Clarity Blend: Combines Delta 8, THCv, CBD, and CBG for sharp focus and clean decision-making.
• Charged Blend: Built around THCv, and CBG for uplifting energy without the jitter.
• Creativity Blend: Features, Delta 8, and Delta 10 to spark imagination and reduce mental blocks.
• Dream Blend: A calming combination of Delta 8, CBN, and THCp designed for deep rest.
• Euphoria Blend: Packs Delta 8, CBD, CBG, and THCp for a wave of positivity.
• Tranquility Blend: Uses CBD and CBN to support calm and stress relief.
• Recover Blend: Built with THCm and Delta 8 to ease tension after physical exertion.
• Desire Blend: Combines THCh and Delta 11 for social intimacy and a lighthearted buzz.

 

 

 

These blends are available across Mellow Fellow’s full product range – including disposable vapes, vape cartridges, and edibles – so you can stay in the same mood profile while switching formats throughout the day.

The Widest Product Range of the Three Brands

Mellow Fellow is the only brand in this comparison with a product catalog that spans every major consumption format:

• Disposable vapes and vape cartridges in terp sauce, live resin, and blend formats
• A full edibles lineup covering Delta 9 live resin gummies, THCp Bursts, M-Fusions bags, and wellness gummies
• Hemp-derived drinks including seltzers and mixers
• THCa and THCp flower, prerolls, and infused blunts
• THCa concentrates like the 2g Budder Jars in strains such as Garlic Cookies, Kush Cake, and Peach Oblivion
• Terp sauce syringes for dabbing or topping flower
• A dedicated wellness line of tinctures, softgels, and roll-ons

That depth makes Mellow Fellow the practical choice whether you vape, eat edibles, prefer flower, or want a sip-and-chill hemp drink. No other brand in this comparison comes close to that format breadth.

 

 

 

Product Quality and Safety

Every Mellow Fellow product is tested at third-party, ISO-certified labs. COAs are posted directly on each product page and cover cannabinoid content, terpene profiles, residual solvents, heavy metals, and pesticides. The formulation process behind each mood blend reflects pharmacist-level precision, with cannabinoid ratios chosen to reinforce specific desired effects rather than to maximize any single number on a label.

Positives of Mellow Fellow

• Mood-First Design: Every product maps to a clear use case – focus, sleep, creativity, recovery, euphoria.
• Pharmacist Formulation: Blends are built by professionals using compound synergy, not random stacking.
• Broadest Catalog: Disposables, cartridges, edibles, drinks, flower, concentrates, wellness – all under one brand.
• Full COA Transparency: Lab results accessible on every product page, covering the most thorough test panel of the three brands.
• Loyalty Program: Mellow Fam rewards earn points with every purchase, with 100 points translating to $10 credit.
• Education and Guidance: Deep cannabinoid guides, strain-specific posts, and effect-based shopping tools help customers buy with confidence.

What Could Be Better

• Selection Depth Can Feel Large: With nine mood blend profiles across multiple formats and sizes, first-time buyers may want to start with the popular products page to narrow down quickly.

3Chi Overview

3Chi launched in 2019 and is widely credited as one of the first brands to commercialize Delta 8 THC at scale. Its founder, a biochemist, built the brand on a belief that hemp-derived cannabinoids represented the future of consumer wellness – and staked the company’s reputation on scientific credibility and product transparency.

The brand now covers a wide cannabinoid range, including Delta 8, Delta 9, Delta 10, THCv, CBD, CBN, CBG, and CBC. Product formats include vapes, edibles, tinctures, concentrates, and flower. For buyers looking to compare Delta 8 specifically to other cannabinoids before choosing a product, our Delta 8 vs Delta 9 THC guide breaks down the differences in effect and onset timing.

3Chi Core Features

Extensive Cannabinoid Selection

3Chi’s primary selling point is access to a wide range of cannabinoids from one source. From the familiar (Delta 8, CBD) to the less common (THCv, CBG, CBC), the brand provides options for customers who want to experiment across the spectrum without switching brands. Researching alternatives to THC you may not have heard of is a good starting point for buyers new to the broader catalog.

True Strains and Strain-Specific Products

3Chi’s True Strains line replicates terpene profiles from classic cannabis cultivars, including Sour Diesel, OG Kush, and Granddaddy Purple. These products are designed to deliver the flavor and effect associations users already know from traditional cannabis – useful for buyers whose purchasing instinct is strain-driven rather than effect-driven.

Third-Party Testing

3Chi conducts full-panel third-party lab testing and publishes COAs for customers to review before purchasing. Tests cover potency, cannabinoid content, and common contaminants including pesticides, heavy metals, and residual solvents.

Positives of 3Chi

• Trusted history as one of the earliest Delta 8 brands with a scientific founding story.
• Broad cannabinoid coverage across a wide product type range.
• True Strains line for customers who shop by strain.
• Accessible pricing and full-panel COA transparency.

What Could Be Better

• No loyalty or rewards program to recognize repeat buyers.
• U.S.-only shipping restricts access for international customers.
• Limited mood- or effect-based product organization, which can make selection harder for beginners.

 

 

 

Delta Effex (Delta Extrax) Overview

Delta Effex launched in 2020 as the hemp cannabinoid brand of Savage Enterprises, a California-based e-liquid company founded in 2014. The brand has since been rebranded as Delta Extrax, though both names remain recognizable across the market. What started as a Delta 8 brand has grown into one of the more innovation-forward operations in the hemp space, consistently among the first to market with novel cannabinoid products.

Delta Extrax was an early mover on THCp, THCa live resin carts, and complex multi-cannabinoid blends. Their Adios and Lights Out collections feature aggressive stacks pairing THCa, Delta 9P, THCp, THCjd, and Delta 8 for high-potency, experienced-user-focused experiences. The manufacturing background from Savage Enterprises shows in the consistency of their gummies, which are machine-filled for precise dosing at every piece.

Delta Effex Core Features

Aggressive Cannabinoid Innovation

Delta Effex (Delta Extrax) has positioned itself as a brand that chases the next compound. They were early on THCjd, THCa, and THCp when most brands were still working through their Delta 8 catalogs. THCp in particular has drawn significant research attention since its 2019 discovery – the Citti et al. study published in Scientific Reports found THCp’s in vitro CB1 receptor binding affinity to be roughly 33 times greater than that of Delta 9 THC, with a Ki of approximately 1.2 nM compared to Delta 9’s Ki of approximately 40 nM. 

Research into THCp’s pharmacology has since been discussed in peer-reviewed contexts including a 2025 PMC paper on CB1 ligand affinity. Delta Extrax capitalized on that early interest with a range of THCp vapes and edibles aimed at experienced users.

If you’re curious about how THCp compares to other potent cannabinoids, our THCp potency guide covers what the research says and what to expect in practice.

Multi-Cannabinoid Stacks for Experienced Buyers

Delta Effex’s signature products are its blended collections – particularly the Adios series, combining THCa, Delta 9P, and Delta 8 with live resin – and the Lights Out collection, which pairs THCh and THCjd for high-intensity effects.

These are products designed for buyers who have built some cannabinoid tolerance and want a more demanding experience, not products aimed at new or casual users. That focus on high-potency stacks is a clear brand identity, but it also means the catalog lacks guidance around how specific products will feel.

Testing Standards

Delta Effex runs a two-phase testing process: internal checks before sending each batch to ISO-certified third-party labs. COAs cover potency, purity, pesticides, heavy metals, and residual solvents and are available on the product pages.

Positives of Delta Effex

• Early and consistent innovation across emerging cannabinoids (THCjd, THCa, THCp, THCh).
• Machine-filled gummies for precise, consistent dosing at each piece.
• Certified manufacturing facility with ISO-certified third-party lab testing.
• Strong product variety spanning standard to extreme-potency formats.

What Could Be Better

• U.S.-only shipping limits access for international buyers.
• Product descriptions could do more to guide newer buyers through effect expectations.
• No verified on-site customer review system to help prospective buyers gauge real-world results.

3Chi vs Delta Effex vs Mellow Fellow: Product Selection

3Chi covers the widest range of individual cannabinoids – Delta 8, Delta 9, Delta 10, THCv, CBD, CBN, CBG, CBC – and organizes much of its catalog around strain names and single-noid formats. It is a reliable choice for buyers who want access to a broad spectrum of compounds without having to piece together options from multiple brands.

Delta Effex (Delta Extrax) focuses more on multi-cannabinoid stacks and novel compounds, targeting experienced users who want high-potency, layered experiences. The catalog is well-suited to buyers who have already explored basic cannabinoids and want something with more intensity or complexity. Readers who want to know how long high-potency cannabinoid effects typically last will find our guide on how long THCp effects last useful for setting expectations.

Mellow Fellow is the only brand of the three with a catalog that covers every consumption format – disposables, cartridges, edibles, drinks, flower, concentrates, syringes, and wellness products. More importantly, it organizes that catalog around moods rather than compounds, making the shopping experience far more accessible regardless of how much prior cannabinoid knowledge a buyer brings.

3Chi vs Delta Effex vs Mellow Fellow: Product Quality and Safety

All three brands conduct third-party lab testing, but the depth and accessibility of those results differ.

3Chi publishes COAs online and has built credibility through early transparency in a market that was largely opaque when the brand launched.

Delta Effex runs a two-stage testing protocol at ISO-certified labs, which reflects the Savage Enterprises manufacturing background. Their standards are consistent and verifiable.

Mellow Fellow tests every product at third-party labs with the most comprehensive panel of the three: cannabinoid content, terpene profiles, residual solvents, pesticides, and heavy metals, all accessible directly from each product page via the testing page. The pharmacist-formulated blends add another layer of quality assurance – not just testing raw material, but designing products with compound interactions in mind.

Research into cannabinoid purity and formulation consistency matters more as the alt-cannabinoid market grows. 

A 2024 review published in Molecules on the chemistry and pharmacology of Delta 8 THC noted that product labeling accuracy in the broader market can vary significantly, reinforcing why third-party testing with publicly available COAs is a non-negotiable baseline. A 2023 review in RPS Pharmacy and Pharmacology Reports on Delta 8 pharmacokinetics similarly underlined the importance of transparent sourcing and testing.

3Chi vs Delta Effex vs Mellow Fellow: Brand Reputation and Customer Experience

3Chi carries the credibility of being among the first. Long-time alt-cannabinoid users often recognize the name, and the brand’s scientific founding story holds up. Customer experience is functional but not notably guided – buyers are expected to bring their own cannabinoid knowledge.

Delta Effex has built a reputation for being ahead of the curve on new compounds. Its community rewards early adopters and enthusiasts who follow cannabinoid innovation closely. The experience suits experienced buyers more than newcomers.

Mellow Fellow has built its reputation around making cannabinoids approachable. Mood-specific naming and organized shopping tools make product selection intuitive. The Mellow Fam rewards program recognizes loyal customers with points on every purchase. Guides on topics like mood-matching for beginners and what the strongest legal cannabinoid is help customers build confidence at their own pace.

For buyers new to cannabinoids, Mellow Fellow’s education-first approach is a meaningful advantage. For experienced users who know exactly what compound they want in exactly what ratio, all three brands can serve that need – but only Mellow Fellow also covers it with formulated context.

3Chi vs Delta Effex vs Mellow Fellow: Pricing and Value

3Chi and Delta Effex both offer competitive pricing structures, with 3Chi slightly more accessible on entry-level products.

Delta Effex pricing trends higher, particularly on its more complex and higher-potency collections, reflecting the premium ingredients and advanced blending involved.

Mellow Fellow prices its products in the mid-to-premium range, but the value calculation is different. Buyers are not just purchasing cannabinoids – they are purchasing a formulated experience built around a specific mood, backed by professional formulation and comprehensive testing. 

The Mellow Fam rewards program and seasonal promotions add meaningful long-term value for repeat customers. Exploring bundle deals is a reliable way to access premium formats at a better per-unit price.

3Chi vs Delta Effex vs Mellow Fellow: Which Is the Best Cannabinoid Brand?

Here is a scoring breakdown across five core categories on a 5-point scale:

 

3Chi and Delta Effex both earn their place among the better hemp-derived cannabinoid brands. 3Chi is right for buyers who want access to a wide array of individual cannabinoids from a trusted, established source. Delta Effex (Delta Extrax) is the better pick for experienced users who want aggressive, high-potency multi-cannabinoid formats and don’t need effect guidance.

Mellow Fellow leads across every category because it solves the problem most cannabinoid buyers actually have: knowing what they want to feel and finding a product built to deliver that consistently.

Why Mellow Fellow Is the Best Bet for Most Buyers

For anyone who has been disappointed by alt-cannabinoid products that delivered inconsistent results, Mellow Fellow’s pharmacist-formulated approach addresses the root cause. Most vapes and gummies in the market are built around a single cannabinoid, diluted with carrier oil, and named after a familiar strain. That’s a different proposition than a blend where a professional has selected specific cannabinoids and terpenes because of how they interact.

The THCp discovery paper published in Scientific Reports in 2019 – the original Citti et al. study on PMC – made clear that cannabinoid binding affinity is not uniform. THCp’s dramatically higher CB1 affinity compared to Delta 9 THC means that which cannabinoids go into a blend, and in what ratios, matters enormously for the resulting effect. Mellow Fellow’s pharmacist formulation process takes that seriously. Random cannabinoid stacking does not.

Pair that formulation approach with the broadest product catalog in the category – covering disposable vapes, vape cartridges, edibles, drinks, flower, THCa concentrates, terp sauce syringes, and the full wellness range – and Mellow Fellow is the clearest all-in-one option for buyers who want to stay with one trusted brand across their whole routine.
