Drostanolone (Masteron)

Drostanolone propionate, sold as Masteron, is a 19-nor androgen with almost no anabolic activity and a very high androgen receptor affinity. That is the whole point of it: it is not a mass drug, it is a finishing drug, used to harden the look, dry out the face, and sharpen the presentation in the last weeks of a cut. At 100mg a day - and it is usually dosed daily - it is a mild androgen in absolute terms, but the receptor affinity means it does more than the maths suggests.

Why it keeps its following

Because it dries you out without wrecking your joints or your appetite, and because at sane doses it is well tolerated by men who react badly to other androgens. It is not a beginner's first compound, and it is definitely not something to run for mass.

Verification

• Label names drostanolone propionate and mg per ml.
• Clear solution, no particulates.
• Batch, expiry and seal intact.
• Store cool; a short ester degrades faster in a warm room than a long one does.
