Topical Antiandrogens

Two ways to take DHT out of the equation: stop your body making it, or block the seat it needs to sit in. Everything here does the second — it occupies the androgen receptor at the follicle and leaves your hormones where they are.

SPECIMENS: 03
THE THREE, COMPARED

Same target. Different evidence.

  • RU58841

    The longest user history of the three — roughly two decades — and by a wide margin the lowest cost per month. It also has no completed late-stage human trials. That trade is the whole conversation.

    ~20 years of use · no phase 3

  • Pyrilutamide (KX-826)

    The newer of the Chinese-developed antiandrogens. Human trial data behind it, and a shorter, thinner record of long-term use. Sits between the other two on price.

  • Clascoterone (CB-03-01)

    The one that finished phase 3 — 1,465 men across SCALP-1 and SCALP-2 — designed to break down into an inactive compound in the skin after it works.

BEFORE YOU PICK ONE

Run one properly, not three badly.

Most people should run one antiandrogen, properly, for at least six months before judging it. Stacking three does not triple anything — it mostly triples what you spend and makes it impossible to know what worked.

On price: everyone in this category buys raw material at roughly the same price. So when one seller is far cheaper than another, that gap came from somewhere — a lower concentration than the label claims, a batch nobody tested, or older powder. Cheapest is a reasonable thing to want. It is just not the same thing as best, and it is worth asking any seller, including us, what they saved to get there.

All of it is mixed and bottled inside the EU, batch-tested before dispatch, and shipped in two to five working days without customs. Sold for research use.

What else the lab makes.

RU58841 Topical Solution

4.9 (88)·5/8% · 30/50/100 ml

2.5/5% · 50 ml

Blocks the androgen receptor at the follicle, then breaks down in the skin into an inactive form.
