Every Gonadorelin listing, cheapest per mg first
Sticker prices hide the size, so listings are ranked by what a milligram actually costs — with independently tested purity where it exists. All 13 are here: the last 2 are listings whose vendor never published a strength we can read, so they have no per-mg figure to sort on.

Real $/active mg divides the price-per-mg by the measured purity — the honest cost of the actual peptide, so a 90%-pure vial isn’t compared as if it were 99%. Too cheap? flags a listing far below the market rate — often underdosing or a fake, not a deal. The crown marks the cheapest non-outlier; best value marks the lowest real cost per active mg. A vendor shown as Unavailable or Low stock is priced here but not currently buyable.
Understand this compound
What is Gonadorelin?
FDA-approved moleculea.k.a. Factrel, LutrepulseA lab-made copy of the brain signal that starts the reproductive-hormone chain. Once an approved diagnostic drug, now mostly seen in research on testosterone and fertility signaling.
Good to know: No currently FDA-approved product exists in the US, so any present-day use relies on compounded material outside the original approved, quality-controlled formulation.
How does Gonadorelin work?
The science
A synthetic decapeptide identical to natural GnRH; pulsatile dosing stimulates pituitary LH/FSH release, while continuous dosing paradoxically downregulates the GnRH receptor and suppresses gonadotropin output.
Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.
What is Gonadorelin researched for?
Studied historically for diagnosing pituitary gonadotrope function and for treating hypothalamic amenorrhea or hypogonadotropic hypogonadism.
- Reproductive & hormonalStudied in reproductive-hormone and endocrine-axis research.
How far has the research gone?
FDA-approved (historically, now discontinued) — approved in 1982 as Factrel for pituitary function testing, but no FDA-approved gonadorelin product is currently marketed in the US.
Where the science stands — an approved drug is not the same as the research-grade material a vendor sells, which is unregulated regardless.
What should I check before buying?
- Independent purity. Look for a third-party COA (Janoshik or MZ) showing a measured purity — not just a number the vendor typed.
- Batch match. The strongest evidence is a certificate for the exact batch you’ll receive, attributed to this vendor — check the cross-verification on the listing.
- Vendor reputation. See how the vendor is talked about in the community before trusting a new name.
Research context only — VialGrade never gives dosing, medical, or human-use guidance.
The lab evidence
What we could verify
Each row is a separate question with its own answer — one green row never vouches for the rest.
Identity
PartialThe vendor advertises third-party testing; no independent record confirms it yet.
Measured purity
UnknownNo independent purity measurement on record.
Batch traceability
UnknownNo batch on this listing matches an independent record.
Sterility
Not testedA purity certificate doesn't measure this — no such test on record.
Dose accuracy
UnknownNot something VialGrade measures — no test on record.
testing advertised, but not independently confirmed
This listing advertises testing, yet no independent record in our index references Core Peptides for Gonadorelin. That doesn't prove the certificate is fake — but until it resolves at the lab, treat the testing claim as unbacked, not verified.
- Vendor claim. Advertises testing.
- Independent confirmation. No record found for Core Peptides. Verify the certificate at the lab before trusting it.
Cross-checks the vendor’s testing claim against independent lab records. Read from the certificate, not re-measured by VialGrade. Purity is not a grade. Never a statement that a product is safe, sterile, or correctly dosed. What “grade” actually means

This is a prescription drug in the US
This is an approved GnRH drug — an FDA-approved prescription medication. Buying a “research” version sidesteps the prescription requirement and the approved, quality-controlled supply chain. The FDA has warned about and acted against unapproved and compounded copies. Higher legal and safety exposure than an unapproved research peptide.
General information, not legal or medical advice. VialGrade sells nothing and encourages no human use.
