Trusted Kalpa Pharmaceuticals Proviroxyl Source

Proviroxyl is an oral androgen containing Mesterolone, developed by Kalpa Pharmaceuticals. This non-aromatizing steroid is used primarily to manage symptoms of low testosterone, support libido, and enhance androgen levels during cutting or contest prep.

Unlike other oral steroids, Mesterolone is not 17-alpha alkylated, meaning it has a much lower risk of liver toxicity. Bodybuilders use it to maintain libido and mental clarity while on suppressive anabolic cycles, and as a mild anti-estrogen alternative in stacks.

Key Benefits of Proviroxyl

Increases androgen levels without converting to estrogen
Enhances hardness and definition during cutting phases
Supports libido and mood during AAS cycles
Minimal impact on liver and blood pressure

Dosage & Usage Guidelines

Typical dosing ranges between 25–100 mg/day. It is often used alongside other anabolic steroids such as Testoxyl Cypionate or Dianoxyl. Because of its anti-estrogenic properties, it can also help modulate estrogen-related side effects in a stack.

Side Effects

Proviroxyl is generally well-tolerated. Since it doesn't aromatize, estrogenic side effects like gynecomastia and water retention are avoided. However, some users may experience hair loss or increased aggression at higher doses.

Post-Cycle Therapy (PCT)

Proviroxyl does not require standalone PCT, but if used alongside suppressive compounds, follow with a proper PCT including Clomixyl or Nolvaxyl.
