Blackstone Labs | PCT V | 60 Capsules

Blackstone Labs PCT V is a stim-free hormone-support formula built around a straightforward post-cycle support concept: help manage estrogen-related rebound, support androgen balance, add basic antioxidant coverage, and include ancillary support ingredients that are common in physique-sport recovery protocols. This is not a broad-spectrum health stack and it is not a pharmaceutical PCT substitute. It is a fully disclosed, capsule-based supplement that combines one mechanistically relevant aromatase-focused compound with several supporting ingredients aimed at the hormonal environment many users try to stabilize after a suppressive training or supplementation phase.

The centerpiece is Androst 3,5-Dien-7,17-Dione at 37.5mg, commonly known in the sports supplement market as arimistane. This ingredient is used for its aromatase-inhibiting role, meaning it is designed to reduce conversion of androgens into estrogen by interacting with the aromatase enzyme. In practical terms, this is the ingredient most directly tied to the formula’s PCT positioning. The 37.5mg dose sits within the range commonly seen in non-prescription post-cycle products and should be understood as the primary driver of the formula’s intended effect profile.

Tribulus terrestris standardized for saponins is included at 250mg. Tribulus is one of the most recognizable ingredients in hormone-support formulas, but the research context matters: it is more consistent for libido and general male vitality support than for meaningfully increasing testosterone in healthy resistance-trained men. At 250mg, this is not an aggressive dose versus many standalone tribulus products, but standardized extract is preferable to raw powder because saponin content is what formulators are typically targeting. Users are more likely to notice this through subjective metrics like drive and libido than through dramatic body-composition changes.

Saw Palmetto berry extract at 160mg adds a classic androgen-balance angle. Saw Palmetto is widely used for 5-alpha-reductase modulation, meaning it is often included to influence conversion of testosterone into DHT. In a post-cycle context, that makes sense as a support ingredient for users who want a more balanced hormonal support profile, especially when they are conscious of hairline, skin, or prostate-related concerns. The 160mg dose is in line with common supplemental use, though extract standardization details would have made dose interpretation stronger.

N-Acetyl Cysteine at 125mg provides glutathione-supporting antioxidant coverage. NAC is a precursor to glutathione, one of the body’s key endogenous antioxidants, and it is often included in support formulas for liver and oxidative stress considerations. That said, 125mg is well below the doses typically used in more targeted NAC products, where 600mg or more is common. It still contributes to the formula’s support architecture, but it is not a standalone liver-support dose.

Alpha Hydroxy Laxogenine at 25mg rounds out the formula with a plant-derived compound often positioned for recovery, lean-tissue support, and training resilience. Human data here is limited compared with mainstream sports nutrition ingredients, so expectations should remain grounded. It is best viewed as a speculative adjunct rather than a primary reason to buy the formula.

As a system, PCT V combines an estrogen-management anchor, libido-oriented botanical support, DHT-conscious support, and a small antioxidant component. Its biggest strengths are label transparency and a clear formula identity. Its limitations are equally important: NAC is underdosed relative to standalone use, Tribulus is not a clinically reliable testosterone elevator, and Laxogenine remains evidence-light. Day 1, most users will notice little in the way of acute sensation because this is a non-stimulant capsule formula. Over 2-4 weeks, the experience is more about steadier subjective support: less concern around estrogen rebound, more consistent sense of hormonal balance, and better adherence because the formula is simple enough to use daily.
