Primobolan Cycle Guide: Arnold's Favourite Worth Price? – Immortal Medicals

Arnold called it his favourite compound. Primobolan built some of the most aesthetic physiques in bodybuilding history. But at £80+ per 10ml vial, it costs five times more than testosterone cypionate for a fraction of the anabolic power.

So what makes methenolone enanthate worth the premium? The answer lies in what Primobolan doesn’t do as much as what it does.

No aromatisation. No water retention. No hair loss for most users. No liver toxicity. Just steady, quality muscle tissue that you actually keep post-cycle.

Methenolone enanthate is a DHT derivative with a unique molecular structure. The addition of a 1-methyl group prevents aromatisation entirely — your estrogen levels won’t budge running Primobolan solo.

Unlike most DHT derivatives, Primobolan doesn’t bind strongly to scalp androgen receptors. Where Masteron or Winstrol can accelerate male pattern baldness, Primo remains relatively hair-safe for most users.

The enanthate ester provides a 5-7 day half-life, allowing twice-weekly injections. Each millilitre delivers roughly 70mg of active methenolone after ester weight — significantly less than testosterone’s ~180mg per 250mg dose.

Users often compare Primobolan to Anavar for its mild nature and quality gains. Both compounds shine in cutting phases, but they work differently:

Primobolan requires higher doses than most steroids to produce meaningful results. The compound’s mild nature means conservative dosing often disappoints users expecting dramatic changes.
