Gonadorelin: what it is, what the evidence says, and its real status

The fertility-preservation companion to testosterone therapy, it keeps the body's own signaling switched on.

Can you actually get it?

Plain-English verdict: Join waitlist.

Regulatory status: 503A interim Category 1 (enforcement discretion, not the 503A Bulks List).

How does Gonadorelin work?

A synthetic gonadotropin-releasing hormone that stimulates LH/FSH, maintaining testicular function and fertility during testosterone therapy.

What it does — and what it does not do

What it does: Used to preserve fertility and natural testicular signaling alongside TRT.

What it does not do: Compounded forms are not FDA-approved, and it is not a standalone testosterone therapy.

How honest is the evidence?

Evidence grade B — Good human evidence.

established GnRH mechanism; modern TRT-adjunct data moderate

A grade measures how much human evidence exists, not whether a molecule is good, safe, or worth your interest. Read our grading methodology for what each grade means.

What we still don't know: Optimal protocols alongside modern TRT are still being refined.

WADA status: Banned (S2).

How it is taken

What the literature reports: subcutaneous, 2–3× weekly. Educational only, no dose figures.

Who should not take it

WADA S2 banned; clinician oversight required as part of a hormonal protocol.

Compounded medications are not FDA-approved. We keep two signals separate and never collapse them: whether you can get something, and what the rule currently says. See the live FDA Peptide Tracker for status.
