The Trustpilot score is 2.2 out of 5 from 34 reviews, with complaints concentrated on shipping delays and customer service inconsistency. The VEG-PRO protein powder was subject to a Proposition 65 consent judgment in California in 2022 for lead and cadmium content.
This review covers Steel Supplements’ product lineup, ingredient quality, safety concerns, customer feedback, pricing, and how the brand compares to competitors to help buyers make an informed purchase decision.
What Is Steel Supplements?
Steel Supplements is a sports nutrition brand founded in 2016 by Jason Huh, evolving from Elite Nutrition and Smoothie into a supplement company with an FDA-registered, U.S.-based manufacturing operation and a product lineup spanning pre-workout, protein, recovery, fat loss, and prohormone supplements. The brand’s mission is to advance physical and mental health through science-backed formulas.
Jason Huh founded the company with a stated commitment to the highest quality ingredients tested for accuracy and purity before and after manufacturing. The company’s flagship product, ADABOLIC, is a 30+ ingredient pre/intra/post-workout formula Huh personally formulated based on protocols used with his athletes.
Steel Supplements sells directly through its website at steelsupplements.com with free shipping on orders over $150 (USD). The company also offers a wholesale program, rewards points, and stacked bundles for buyers targeting specific fitness goals including muscle building, fat loss, and hormonal support.
Who Makes Steel Supplements?
Steel Supplements was founded by Jason Huh, who also serves as the face of the brand’s science and product development, with scientific advisory support from Dr. Paul Henning, whose research informs formulation decisions for key products like ADABOLIC. Manufacturing occurs in FDA-registered facilities in the United States.
The brand grew from a supplement retail storefront called Elite Nutrition and Smoothie, which Huh rebranded as Steel in 2016 when the supplement line launched. The company operates under Steel Supplements Inc. and Steel Beverages LLC, covering both supplement and energy drink product lines.

Are Steel Supplements Good Quality?
Steel Supplements manufactures in FDA-registered U.S. facilities using globally sourced ingredients tested for accuracy and purity before and after production, with the company citing 60,000+ customer reviews as evidence of product effectiveness across the lineup. The brand emphasizes science-backed formulation and premium ingredient standards.
ADABOLIC uses over 30 ingredients formulated around GlycoMax, which the company describes as the first scientifically proven performance-enhancing drink compound on the market. The formula targets pre-workout energy, intra-workout endurance, and post-workout recovery in a single product. N.O.7 delivers a non-stimulant nitric oxide booster in one capsule format for pump and vasodilation.
The VEG-PRO plant protein powder was subject to a Proposition 65 consent judgment in California in 2022. Environmental Health Advocates filed a complaint alleging VEG-PRO contained lead and cadmium without sufficient health hazard warnings as required under California law. Steel denies the allegations but agreed to the consent judgment. Buyers in California should note that Prop 65 warnings are required for this product.
Steel Supplements Quality Summary:
- Manufactured in FDA-registered U.S. facilities
- Ingredients tested for accuracy and purity before and after manufacturing
- 60,000+ on-site customer reviews
- VEG-PRO subject to California Prop 65 consent judgment (lead/cadmium)
- Prohormone category products require careful review before use
Is Steel Supplements Third-Party Tested?
Steel Supplements states that all products are tested for accuracy and purity before and after manufacturing in its FDA-registered facility, but the company does not prominently display third-party certification badges like NSF Certified for Sport or Informed Sport on its product lineup. Independent third-party testing documentation is not featured publicly in the same way as brands like Thorne or Double Wood.
The absence of NSF Certified for Sport status is relevant for competitive athletes subject to drug testing. The prohormone products (1-ANDRO, 4-ANDRO, 3-EPI-ANDRO) sit in a regulatory gray area in the supplement market. Athletes competing under USADA, WADA, or NCAA jurisdiction should not use Steel’s prohormone products without confirming compliance with their governing body’s banned substance list.
Does Steel Supplements ADABOLIC Work?
Steel Supplements ADABOLIC is a stimulant-free pre/intra/post-workout formula with 30+ ingredients targeting glycogen restoration, muscle tone, endurance, and recovery, with over 20 serving and 40 serving tub sizes available and strong positive feedback on the company’s own review platform. The formula avoids stimulants, making it stackable with other caffeinated pre-workouts.
ADABOLIC includes Vitamins C, B1, B2, B3, B5, B6, and B12, Magnesium, Leucine, Glutamine, and GlycoMax. The formula is designed by Jason Huh and informed by Dr. Paul Henning’s research. The product is categorized as: stimulant-free pre-workout, muscle glycogen restorer, muscle tone enhancer, recovery accelerator, and endurance maximizer.
Customer reviews on Steel’s own site rate ADABOLIC highly. One buyer noted the N.O.7 product shows visible pump difference during arm training. Another rated FOCUSED-AF at 5 stars for daily work and focus use. The Cardio Stack including N.O.7 received 5-star reviews from buyers targeting fat loss and vascularity.
What Are the Benefits of Steel Supplements?
Steel Supplements targets five primary performance categories: muscle building and recovery (ADABOLIC, WHEY-ISO), pump and vasodilation (N.O.7, PUMPED-AF), fat loss (SHREDDED-AF, Ultimate Shred Stack), cognitive focus (FOCUSED-AF), and hormonal support (ALPHA-AF, 1-ANDRO, 4-ANDRO). Each product targets a specific training or body composition goal.
The non-stimulant N.O.7 works by increasing blood oxygen levels, nutrient flow, and vasodilation. It is designed to deliver visible pump results within one capsule taken 30 minutes before training. The formula is stackable with stimulant pre-workouts for buyers who want both energy and pump from separate sources.
FOCUSED-AF targets cognitive performance and daily focus for both training and work. Customer reviews note it as suitable for regular daily use, with SHREDDED-AF reserved for more demanding days due to its stronger thermogenic effects. The combination allows buyers to modulate intensity based on the day’s demands.
Steel Supplements Performance Categories:
- Muscle building and recovery: ADABOLIC, WHEY-ISO, ADALoad
- Pump and vasodilation: N.O.7, PUMPED-AF, HyperBolic
- Fat loss: SHREDDED-AF, Ultimate Shred Stack, Cardio Stack
- Cognitive focus: FOCUSED-AF, ATP-FUSION
- Hormonal support: ALPHA-AF, 1-ANDRO, 4-ANDRO, 3-EPI-ANDRO
What Do Steel Supplements Reviews Say?
Steel Supplements receives mixed reviews across platforms, with 60,000+ positive reviews on its own website concentrated on product effectiveness, and a 2.2 out of 5 TrustScore from 34 reviews on Trustpilot, where complaints focus primarily on shipping reliability and customer service quality. The on-site and third-party review profiles diverge significantly.
On-site reviews praise SHREDDED-AF, ADABOLIC, N.O.7, and WHEY-PRO for effectiveness. One customer called PRE Sample Packets ‘easily the best pre-workout Steel has available’ and praised the taste and lack of jitter. FOCUSED-AF received 5 stars for daily use by both male and female buyers targeting work focus alongside training performance.
Trustpilot reviews score poorly due to shipping complaints. One reviewer rated the brand 2 stars specifically for shipping issues, noting that paying extra for expedited shipping still resulted in late deliveries. A 4-star reviewer acknowledged the products work but flagged inconsistent customer service. The TrustScore of 2.2 out of 5 reflects a small review sample (34 reviews) heavily influenced by fulfillment experience rather than product quality.
What Are Common Steel Supplements Complaints?
Common complaints about Steel Supplements include unreliable shipping timelines even for paid expedited orders, inconsistent customer service quality, higher price points relative to generic competitors, and the Proposition 65 consent judgment for VEG-PRO’s lead and cadmium content in California. These issues appear repeatedly across third-party review platforms.
Shipping complaints are the dominant negative theme on Trustpilot. Buyers report paying for faster shipping and receiving orders outside the promised window anyway. The free shipping threshold requires orders over $150 (USD), which may push buyers toward bundling products to qualify rather than purchasing single items.
The VEG-PRO Prop 65 issue is a legitimate safety flag for California buyers and buyers who are particularly sensitive to heavy metal exposure. The consent judgment requires California warnings for lead and cadmium. Buyers choosing plant protein should consider this when evaluating VEG-PRO versus other brands.
Pros:
- Made in USA in FDA-registered facilities
- ADABOLIC and N.O.7 receive strong on-site reviews
- Wide product range covering all major training goals
- Stimulant-free options (N.O.7, ADABOLIC) for stacking
Cons:
- Trustpilot score of 2.2 out of 5 driven by shipping complaints
- VEG-PRO subject to Prop 65 consent judgment in California
- No prominent third-party testing certification (NSF, Informed Sport)
- Prohormone products not suitable for tested athletes
- Free shipping only on orders over $150 (USD)
Steel Supplements vs. Competitors?
Steel Supplements competes against Optimum Nutrition, MuscleTech, and Ghost in sports nutrition, with Steel differentiating on its prohormone-category products and multi-phase workout formulas, but facing disadvantages in third-party testing transparency and customer service consistency compared to premium competitors. Price positioning is mid-tier.
Competitors like Ghost and Legion Athletics offer full ingredient disclosure and actively highlight third-party testing documentation. Steel’s site emphasizes product effectiveness and founder-driven formulation but doesn’t match the testing transparency of top-tier sports nutrition brands. Buyers who prioritize verified purity over brand personality have stronger alternatives at similar price points.
Sports Nutrition Brand Comparison:
| Brand | Third-Party Testing | Notable Product | Trustpilot Score |
|---|---|---|---|
| Steel Supplements | In-house testing stated | ADABOLIC, N.O.7 | 2.2/5 (34 reviews) |
| Ghost Supplements | Full label disclosure | Ghost Legend Pre-Workout | Not listed |
| Double Wood Supplements | COAs publicly available | Magnesium L-Threonate, Berberine | Not listed |
| Thorne | NSF Certified for Sport | Multi+ Elite, Basic Nutrients | High rating |
Are Steel Supplements Safe?
Steel Supplements manufactures in FDA-registered U.S. facilities with stated in-house testing for purity and accuracy, but the VEG-PRO protein powder’s Prop 65 consent judgment for lead and cadmium, and the prohormone product category, raise legitimate safety considerations that buyers should evaluate before purchasing. Most core products carry standard supplement safety profiles.
The prohormone products (1-ANDRO, 4-ANDRO, 3-EPI-ANDRO, 19NOR-ANDRO) are testosterone precursor compounds that affect hormone levels. These are not appropriate for individuals under 18. They require post-cycle therapy (PCT) after use cycles. Buyers with pre-existing hormonal conditions, liver concerns, or cardiovascular issues should consult a physician before using any prohormone product.
Standard non-hormonal products including ADABOLIC, WHEY-ISO, N.O.7, and FOCUSED-AF carry typical supplement safety profiles. The company advises following label directions and consulting healthcare providers for individuals with existing health conditions or medications. Products are not intended to diagnose, treat, cure, or prevent disease.
What Are the Side Effects of Steel Supplements?
Side effects for Steel Supplements vary significantly by product category, with standard workout formulas (pre-workout, protein, pump) carrying typical supplement profiles, while prohormone products (1-ANDRO, 4-ANDRO) carry hormonal side effect risks including testosterone suppression, liver stress, and androgenic effects. Post-cycle therapy is required after prohormone use cycles.
SHREDDED-AF contains thermogenic compounds and is described as ‘more extreme’ by customers who use both SHREDDED-AF and FOCUSED-AF. Thermogenic fat burners can elevate heart rate and body temperature. Stimulant-sensitive buyers should start with a half-serving and assess tolerance before using full doses.
How Much Do Steel Supplements Cost?
Steel Supplements prices most products between $25 and $79 (USD), with bundle deals like the Hyperbolic Bundle at $34.99 (USD) and the Ultimate Shred Stack offering per-unit savings over individual product pricing, and free shipping requiring orders over $150 (USD). The prohormone products tend to sit at higher price points than standard supplements.
VEG-PRO plant protein retails at $25 (USD) per bag. Hyperbolic Bundle retails at $34.99 (USD). The 20-serving and 40-serving ADABOLIC tub sizes offer per-serving cost scaling. Bundle purchases allow buyers to hit the $150 (USD) free shipping threshold while reducing the total cost per product.
Are Steel Supplements Worth the Price?
Steel Supplements is worth considering for buyers specifically seeking ADABOLIC or N.O.7 based on their unique multi-phase and non-stimulant pump formulations, but the overall value proposition is weakened by shipping reliability issues, the VEG-PRO Prop 65 concern, and limited third-party testing transparency compared to competing brands at similar price points. The prohormone products require careful self-research before purchase.
Buyers who have had positive direct experience with specific Steel products (ADABOLIC, FOCUSED-AF, N.O.7) report strong satisfaction with product effects. The 60,000+ on-site reviews reflect a loyal customer base that values the formulas. For first-time buyers, starting with sample packs before committing to full-size products reduces risk given the mixed third-party review profile.
Where Can You Buy Steel Supplements?
Steel Supplements sells directly through its website at steelsupplements.com with free shipping on orders over $150 (USD), and also distributes through Amazon, retail supplement stores, and a wholesale program for business buyers. The company has multiple physical retail locations and an energy drink line under Steel Beverages LLC available through separate channels.
Are Steel Supplements Worth It?
Steel Supplements is worth it for buyers targeting the ADABOLIC multi-phase workout formula or N.O.7 non-stimulant pump product, where the brand’s unique formulation approach delivers results not easily replicated by generic alternatives, but buyers should approach the prohormone products, VEG-PRO, and shipping expectations with eyes open. Product effectiveness and shipping reliability tell different stories in the review data.
In fact, the 60,000+ on-site reviews and loyal repeat customer base confirm real product satisfaction for the core lineup. The good news is that ADABOLIC, WHEY-ISO, and the AF-series products are the brand’s strengths. The weak points are shipping consistency, VEG-PRO safety flags, and limited third-party testing documentation. These are the real areas where Steel lags behind premium sports nutrition competitors.
For buyers who know exactly which Steel product they want and can work around the higher free shipping threshold, the core lineup is a solid choice. For buyers evaluating Steel as a general-purpose supplement brand against Ghost, Legion, or Thorne, the transparency and quality assurance gaps are harder to ignore at comparable price points.
