Blackstone Labs PCT V is a comprehensive post-cycle therapy formula designed to restore natural hormone levels, protect muscle gains, and regulate estrogen after intense prohormone cycles. Aggressive supplement cycles can bring the biggest gains you've ever witnessed — in just a few weeks, you can amass size and strength that would normally require years of intense daily training. As quickly as those gains came, that's how quickly they can go, along with your testosterone production, if you don't follow proper post-cycle therapy. PCT V protects your body across five key areas: natural testosterone support via 250mg Tribulus Terrestris, prostate protection and DHT modulation via 160mg Saw Palmetto Berry Extract, antioxidant and liver support via 125mg N-Acetyl Cysteine (NAC), estrogen management via Arimistane, and additional anabolic/recovery support via Laxogenin. Take 1 capsule in the morning and 1 in the evening. Do not exceed 2 capsules per day. Start the day after your last prohormone dose and run for 4-8 weeks depending on your cycle length. Not recommended for women.†

Tribulus Terrestris — 250mg — LH Stimulation and Cortisol Management
Tribulus Terrestris is a Mediterranean plant whose whole structure — including its fruits — has been used medicinally for centuries. In PCT V, it's dosed specifically to increase production of luteinizing hormone (LH), the pituitary signal that tells the testes to resume testosterone production after a prohormone cycle has suppressed the body's natural output. Tribulus also helps reduce stress and cortisol — an important secondary function, since cortisol is incredibly catabolic and a known testosterone killer, meaning elevated cortisol during the vulnerable post-cycle recovery window can actively work against the hormonal normalization PCT V is trying to achieve.†
Saw Palmetto Berry Extract — 160mg — Prostate Protection During Recovery
Saw Palmetto Berry Extract is traditionally used to treat enlarged prostate and to help prevent testosterone from converting to DHT (dihydrotestosterone). In the post-cycle context, this serves two purposes: protecting prostate tissue that may have experienced elevated androgenic stimulation during a DHT-pathway prohormone cycle, and reducing the risk of hair loss that excess DHT conversion can accelerate in genetically predisposed users.†
N-Acetyl Cysteine (NAC) — 125mg — Antioxidant and Liver Support
NAC is derived from the amino acid L-Cysteine and has documented medical use in treating conditions including acetaminophen (pain reliever) poisoning, chest pain, and even collapsed lung — reflecting its potency as a glutathione precursor. In PCT V, NAC increases the body's production of glutathione, the primary antioxidant that supports cellular defense against reactive oxygen species generated during the metabolically demanding process of hepatic hormone processing that a prohormone cycle places on the liver.†
Arimistane and Laxogenin — The Estrogen and Anabolic Layer
Blackstone PCT V will help with the conversion of estrogen so you don't have to worry about it — this is the role of Arimistane, the suicide aromatase inhibitor that permanently deactivates the enzyme responsible for converting residual androgens into estrogen during the post-cycle window, when estrogen rebound is a genuine risk. Laxogenin, added when the formula was updated from PCT IV to PCT V, provides additional non-hormonal anabolic support — helping maintain training performance and muscle protein synthesis during the recovery window without adding any additional hormonal load to a system already working to normalize itself.†
Why PCT Matters — Protecting What the Cycle Built
When taking supplements to reshape your body, the process can cause side effects and, without proper management, can leave you starting from square one. A prohormone cycle can amass size and strength that would normally require years of intense daily training — but that speed cuts both ways: your testosterone production, suppressed by the cycle's exogenous hormonal signals, can crash just as quickly once the cycle ends if not properly managed. PCT V normalizes homeostasis after the body has gone through an intense, extreme hormonal cycle, telling the body to restore its own testosterone production so you can preserve your hard-earned gains and eventually cycle again in the future.†
Frequently Asked Questions
How long should I run PCT V?
Take 2 capsules daily (1 AM, 1 PM) for 4-8 weeks, depending on your prior cycle length. Start the day immediately following your last prohormone dose — don't wait, since natural testosterone recovery begins working against a clock as soon as the cycle ends.†
Can PCT V be stacked with other Blackstone Labs products?
Yes — PCT V is available as part of the Blackstone Labs PCT Stack, which includes PCT V, Eradicate, and Gear Support for comprehensive post-cycle coverage. It can also be stacked with Blackstone Labs Apex Male for an additional natural testosterone boost.†
How does PCT V compare to Hi-Tech Arimiplex?
PCT V has a very similar formula structure to Innovative Labs Hell Raiser PCT, and a comparable profile to Hi-Tech Arimiplex — both are comprehensive multi-mechanism PCT products covering testosterone support, DHT/prostate management, estrogen control, and antioxidant support. The specific ingredient doses and secondary compounds differ slightly between brands.†
Will PCT V cause a positive drug test?
Yes, likely — this product contains ingredients (specifically Arimistane, a DHEA metabolite) that may be banned by some sports organizations and increase the risk of a false positive on a drug test. Consult your sport organization or physician before use if you are a tested athlete.†
How to Take Blackstone Labs PCT V
