Best muscle builder for nattys
"One of the best natural products out there! Black stones never disappoints."
Blackstone Labs EpiSmash brings together Laxogenin and Epicatechin — two of the most potent natural muscle-building compounds on the market — combined into a single liposomal tablet, making it up to 25x more potent than other Laxogenin and Epicatechin products. 5α-Hydroxy-Laxogenin (100mg) is a natural plant-based anabolic shown to increase protein synthesis by 200%, without affecting testosterone production — meaning it doesn't require post-cycle therapy. Acacia Catechu Extract, standardized to 40% Epicatechin (375mg, yielding 150mg of Epicatechin), is a micronutrient isolated from the same category of compounds found in dark chocolate, shown to decrease myostatin — the protein that inhibits muscle growth. Liposomal delivery achieves a 90-99% absorption rate through both fat-soluble and water-soluble coating, bypassing the liver's first-pass degradation that limits standard oral supplements to roughly 33% utilization. Safe for both men and women — whether you're staying completely natural, bridging between cycles, on PCT trying to maintain gains, or a woman looking to cut or bulk, EpiSmash fits. Men take 1-3 tablets daily with a meal; women take 1 tablet daily with a meal. No PCT required.†

Normally, oral supplements have to pass through the liver at least three times before actually entering the bloodstream — by the time that happens, you're only utilizing about 33% of the supplement. Liposomal products are designed to achieve a 90-99% absorption rate, accomplished through both a fat-soluble coating and a water-soluble coating that bypass the liver and shuttle the compound immediately into the bloodstream. For Laxogenin and Epicatechin specifically — both plant-derived compounds with documented but historically inconsistent bioavailability in standard tablet form — this liposomal approach is directly responsible for EpiSmash's claim of being up to 25x more potent than other Laxogenin and Epicatechin products on the market.†
Laxogenin is a natural steroidal sapogenin derived from the Asian plant Smilax Sieboldii, belonging to the group of brassinosteroids — plant hormones structurally related to but functionally distinct from animal androgens. It works by interacting with androgen receptors, stimulating them to increase hypertrophy and tissue repair, elevating muscle protein synthesis while decreasing muscle protein breakdown. This dual anabolic and anti-catabolic activity produces increased muscle mass, improved recovery, reduced injury occurrence, and increased strength, power, and athletic performance — all without the side effects that come with aggressive androgenic supplementation, since Laxogenin does not affect testosterone production and doesn't require PCT. Known for increasing strength, athletic performance, and body composition in as little as 2 weeks, Laxogenin has also been shown to decrease cortisol levels, leading to better metabolism, faster recovery, and muscle growth.†
Epicatechin, delivered here via Acacia Catechu Extract standardized to 40% concentration, is a flavanol found in the same compound family as dark chocolate polyphenols. Its key mechanism is decreasing myostatin — a protein produced in the body that specifically inhibits muscle growth by signaling the body to stop building muscle once a certain threshold is reached. When myostatin levels decrease, the body experiences an increase in the speed of muscle growth and recovery, along with a corresponding increase in follistatin (a myostatin-inhibiting protein that promotes muscle growth) and enhanced fat loss. This mechanism is fundamentally different from Laxogenin's androgen-receptor pathway, meaning the two compounds work on complementary, non-overlapping muscle-growth signaling systems when combined in the same tablet.†
Because neither Laxogenin nor Epicatechin affects testosterone production or works through androgen receptor activation in a way that produces masculinizing effects, EpiSmash is genuinely safe for women — a meaningful distinction from virtually every other product in Blackstone's prohormone lineup (Chosen1, Brutal 4ce, abNORmal, all restricted to men only). EpiSmash is positioned as suitable for anyone: staying completely natural without ever running a hormonal cycle, bridging the gap between two prohormone cycles without losing momentum, maintaining gains during PCT when hormone levels are still recovering, or for women specifically looking to support either a cutting or bulking phase.†
Do I need PCT after taking EpiSmash?
No — EpiSmash is a non-hormonal formula. Neither Laxogenin nor Epicatechin affects testosterone production, so no post-cycle therapy is required, even with continuous use.†
Can EpiSmash be used alongside a prohormone cycle?
Yes — EpiSmash is commonly used to bridge between prohormone cycles, to maintain gains during PCT when natural hormone levels haven't fully normalized yet, or as a standalone natural anabolic for anyone not running a hormonal cycle at all.†
What's the dosing difference between men and women?
Men typically take 1 tablet in the morning and 1 in the evening (up to 3 daily, providing up to 300mg Laxogenin and 450mg Epicatechin). Women take 1 tablet daily with a meal, with some going up to 2 tablets for more pronounced effects.†
Is EpiSmash a steroid?
No — EpiSmash is not a steroid. Laxogenin is a plant-derived brassinosteroid that interacts with androgen receptors without affecting the body's own testosterone production, and Epicatechin is a dietary flavanol. Neither compound is an anabolic-androgenic steroid or a hormone precursor.†
Men: take 1 tablet in the morning and 1 tablet in the evening with a meal (up to 3 tablets daily for more pronounced effects). Women: take 1 tablet daily with a meal (up to 2 tablets for enhanced effects). No cycling or PCT required — safe for consistent, ongoing use. Not for use by individuals under 18 years of age. Consult a physician before use if you have any medical condition or are taking any prescription medications. California Prop 65 Warning applies.†
