Gonadorelin: what it is, what the evidence says, and its real status
A synthetic GnRH used as a TRT adjunct to preserve fertility and natural testicular function, historically approved, now compounded.
Short version: the fertility-preservation companion to testosterone therapy, it keeps the body's own signaling switched on. Historically approved, now compounded; by request and clinician-gated.
Can you actually get it?
Plain-English verdict: Waitlist / education.
Regulatory status: Historically approved · now compounded · By request / education.
By request, clinician-evaluated. Gonadorelin is a synthetic GnRH used alongside TRT to preserve fertility; it was historically FDA-approved and is now used compounded. Compounded forms are not FDA-approved; eligibility is a clinical decision.
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 — established GnRH mechanism; modern TRT-adjunct data moderate. 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 or the knowledge base.
