Blackstone Labs | BSL PCT V 60 CT | 60 Capsules

Blackstone Labs PCT V is a stim-free hormone-support formula designed specifically for the post-cycle window, not as a generic men's health product and not as a replacement for prescription post-cycle care where medically indicated. Its formulation strategy is straightforward: include one clearly active aromatase-focused compound, then surround it with supporting ingredients aimed at androgen balance, antioxidant protection, and muscle-retention support during the period when users often experience a drop in performance, fullness, libido, and overall training momentum.

The anchor ingredient is Androst 3,5-Dien-7,17-Dione, commonly known as arimistane, at 37.5 mg per capsule. With the labeled use of two capsules daily, that yields 75 mg per day, which sits in the range commonly seen in over-the-counter estrogen-control products. Arimistane is used for its aromatase-inhibiting activity, meaning it is intended to reduce conversion of androgens into estrogen. In practical terms, that is why users often look to it post-cycle: to help manage estrogen rebound, support a drier look, and preserve training confidence when hormone levels are in transition. This is the ingredient doing the heavy lifting in the formula from a mechanistic standpoint.

Tribulus terrestris standardized for saponins is included at 250 mg per capsule, or 500 mg daily. Tribulus has a mixed evidence base in the literature for directly increasing testosterone in healthy men, and honesty matters here: it is not a drug-like testosterone restorer. Where it earns its place is the traditional and practical use case around libido, sexual vitality, and subjective sense of masculinity during periods when hormonal disruption can blunt both. The standardization for saponins matters because those compounds are the reason Tribulus is used in these formulas in the first place.

Saw Palmetto berry extract at 160 mg per capsule, or 320 mg daily, lands right in the classic daily range used for male urogenital support. Its main role is tied to 5-alpha-reductase modulation and downstream DHT management. In a post-cycle context, that makes sense for users who want support for prostate comfort and a more balanced androgen environment rather than simply pushing every pathway harder.

NAC at 125 mg per capsule, or 250 mg daily, is a useful inclusion but not a fully built-out clinical liver-support dose on its own. NAC serves as a precursor to glutathione, one of the body's major endogenous antioxidants, and it is commonly used in sports nutrition for oxidative stress and hepatic support. The limitation is dose: many standalone protocols use materially higher daily intakes. Here, NAC should be viewed as supportive background protection, not a comprehensive liver-repair strategy by itself.

Alpha Hydroxy Laxogenine at 25 mg per capsule, or 50 mg daily, is included as a non-hormonal anabolic-support style ingredient intended to help with muscle retention, recovery, and training output. The evidence base is far weaker than for mainstream sports nutrition staples, so this is the least evidence-secure inclusion in the formula. Still, its intended role is clear: help the user feel less flat and less vulnerable to post-cycle performance decline.

As a system, the formula pairs estrogen control from arimistane with supporting layers for libido, androgen balance, antioxidant defense, and muscle-preservation intent. Importantly, there is no proprietary blend here. Every active is fully disclosed, which is a major advantage in a category notorious for vague labels and disguised dosages. Day 1, most users will not feel a stimulant-like effect because this is not that kind of product; what they may notice instead is the psychological reassurance of a purpose-built post-cycle formula. Over 2-4 weeks, the expected experience is steadier hormonal transition, better management of dryness and rebound concerns, and improved confidence in maintaining physique and training consistency.
