Blackstone Labs PCT-V | Reduces Estrogen Levels

Blackstone Labs PCT-V is the ultimate Post Cycle Therapy that functions as both a natural testosterone booster as well as an anti-cortisol and estrogen blocking supplement. This reformulated version of Blackstone Labs PCT IV is now stronger and better than ever, now containing NAC and Laxogenin. These two new ingredients in PCT-V will help you keep your gains and normalize your body's natural hormone production following your prohormone cycle.

About PCT-V

PCT-V functions to repair and protect your body post-cycle using five key components:

  1. Stimulation of natural testosterone production with Tribulus Terrestris
  2. Prevent conversion of DHT with Saw Palmetto extract to protect prostate health and reduce the risk of hair loss
  3. Increase production of the natural antioxidant Glutathione in the body with NAC (N-Acetyl Cysteine), which functions helps prevent liver failure
  4. Decrease catabolic effects (muscle degeneration) using Laxogenin, which will help preserve gains following the conclusion of your cycle
  5. Reduce excess estrogen levels with Arimistane to prevent water and fat retention, mood swings, low sex drive, and lack of energy

The two new ingredients in PCT-V really take your Post Cycle Therapy to a whole new level. NAC (N-Acetyl Cysteine) is a potent antioxidant that plays a vital role in your body's production of glutathione, which is crucial to liver health. NAC promotes the detoxification of harmful agents in your body and supports a healthy liver. Blackstone Labs PCT-V also contains Laxogenin, a naturally occurring plant steroid that helps maintain the results of prohormones without harming the liver or any of the other associated side effects. Laxogenin increases protein synthesis to preserve muscle growth and accelerate repair, while also providing considerable anti-inflammatory effects, control glucose levels, and increase thyroid function.

PCT-V is an essential component of any prohormone cycle and will help you maintain those gains you worked so hard to achieve and keep your new ripped physique!
