Getting started

Typical dosing (research context)

Per-day figures in mg, oral. NOT 17a-alkylated, but low oral bioavailability - so higher doses needed.

What is Primobolan Oral?

Primobolan Oral (Methenolone Acetate) is the oral variant of the mild DHT derivative methenolone. Unlike most oral steroids it is not 17a-alkylated but 1-methylated - making it gentler on the liver but with markedly lower oral bioavailability. It delivers the same clean, dry gains as the injection, just needing higher doses.

How it works

Like injectable primobolan, the oral form mildly activates the androgen receptor, does not aromatize and causes no estrogen side effects. Due to low oral bioavailability less compound reaches the blood - hence the higher mg figures compared to 17a-alkylated orals.

What the research shows

Methenolone has historical clinical use in anemia and muscle wasting. The AAS pharmacology (Kicman 2008, Hartgens & Kuipers 2004) classes it as a mild, non-aromatizing DHT derivative.

Side effects

  • Mild: one of the lower-side-effect orals, lower liver load (not 17a-alkylated).
  • Androgenic (DHT derivative) - hair loss possible in predisposed individuals.
  • HPTA suppression - PCT topic.
  • No estrogen side effects.

Storage

Store dry and cool, protected from light. Out of reach of children.
