Blackstone Labs | BSL PCT V | 60 Capsules

Blackstone Labs PCT V is a fully disclosed post-cycle support formula built around a straightforward strategy: address estrogen-control concerns, support the hormonal environment, and provide a small amount of recovery and organ-support coverage without hiding behind a proprietary blend. This is not a general testosterone booster and it is not a replacement for prescription-grade post-cycle therapy. It is a capsule-based support formula designed for users who specifically want an over-the-counter PCT-style product with transparent dosing.

The formula centers on Androst 3,5-Dien-7,17-Dione at 37.5mg per capsule, commonly known in the category as arimistane. Mechanistically, this ingredient is used for aromatase-related support, meaning it is intended to help manage the conversion of androgens into estrogens. In practical terms, this is the ingredient most directly aligned with the classic PCT goal of controlling estrogen rebound after a cycle. Human evidence is limited compared with pharmaceutical agents, so the exact evidence hierarchy here is weaker than many sports-performance ingredients, but in the supplement category this is the formula’s primary active. At the common use pattern of 2 capsules daily, the daily total reaches 75mg, which sits squarely in the range typically used in PCT-style products.

Tribulus terrestris standardized extract is included at 250mg. Tribulus is often marketed aggressively for testosterone, but the honest read is more nuanced: human data for meaningful testosterone elevation in healthy trained men is inconsistent. Where it can still make sense is in libido support, general vitality positioning, and as part of the hormonal-support architecture of a PCT formula. The standardization to saponins matters because those compounds are the fraction most associated with Tribulus activity, but 250mg is still a moderate inclusion rather than a truly aggressive one.

Saw Palmetto berry extract at 160mg gives the formula a DHT-pathway and prostate-support angle. In post-cycle positioning, this matters because hormonal fluctuations can create concerns beyond just testosterone and estrogen. Saw Palmetto is a familiar inclusion in men’s support formulas, and 160mg is a recognizable dose, though stronger standalone prostate formulas often use more concentrated or more heavily standardized servings.

NAC at 125mg is here as a glutathione precursor and antioxidant support ingredient. NAC supports endogenous antioxidant defenses and is widely used for liver-support positioning because it helps replenish intracellular glutathione. That said, 125mg is a modest dose; it contributes to the formula’s support profile, but it is well below the amounts commonly used when NAC is the primary feature of a recovery or liver-support product.

Alpha Hydroxy Laxogenine at 25mg is included for anabolic-support positioning without acting like a stimulant. Laxogenin has a strong reputation in the sports supplement world for recomposition and recovery support, but the human evidence base remains limited. Subjectively, users typically look for better training recovery, less of a flat post-cycle feeling, and easier maintenance of lean tissue while hormones normalize.

The synergy is clear: arimistane provides the core estrogen-management angle, Tribulus and laxogenine attempt to maintain drive and performance, Saw Palmetto broadens male-support coverage, and NAC adds a basic antioxidant/liver-support component. Just as important, the label is fully transparent. No proprietary blend, no hidden milligrams, and no guessing which ingredient is carrying the formula. Expect very little on day 1 in terms of a dramatic feel; this is not that kind of product. Over 2-4 weeks, the intended experience is steadier post-cycle transition, better maintenance of training quality, and a more controlled hormonal-support routine than going without any dedicated support product.
