Understand this compound
A GHRH-fragment peptide studied in growth-hormone and age-related research.
Good to know: No FDA-approved version is currently marketed; current supply is compounded or research-grade material not subject to the same manufacturing oversight.
A synthetic 29-amino-acid analog of GHRH (GHRH 1-29); binds the GHRH receptor on pituitary somatotrophs to stimulate the body's own pulsatile GH release.
Mechanism of action from published research — how the molecule behaves, not a claim about any product or any human-use effect.
Studied historically for diagnosing and treating growth hormone deficiency; used in ongoing research and compounding for GH-axis support and body composition.
FDA-approved historically (for growth hormone deficiency); marketed as Geref from 1997 until discontinued from the market in 2008 for commercial (not safety) reasons.
Where the science stands — an approved drug is not the same as the research-grade material a vendor sells, which is unregulated regardless.
Research context only — VialGrade never gives dosing, medical, or human-use guidance.
This is a prescription drug in the US
This is a formerly FDA-approved 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.

Compare by real cost
Vials come in different sizes, so the sticker price lies. This ranks every listing by what a milligram actually costs — with independent test purity where we have it.

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.

Commonly researched together
Compounds the research community frequently discusses alongside Sermorelin. Not a protocol or a recommendation — a starting point for what to read about next.
Independent testing
Real, publicly verifiable third-party tests. Purity is read from the certificate itself. A test reflects one lab’s result for one submitted batch — not a guarantee that every vial matches.
Every record below is a real certificate of analysis, gathered two ways: from the public verification feeds that independent labs (like Janoshik) publish, and from the certificates vendors post on their own product pages. We open each certificate document and read the measured purity, content, batch, and date directly off it — a scraper can’t read a number printed inside an image, so this is done by machine vision, then recorded here with a link back to the original.
Nothing here is typed in by a vendor or invented by us. Where a certificate is missing, we say so rather than filling the gap.
We re-check the lab feed, too. A “still listed” tag means the certificate is currently public in Janoshik’s database — we re-verify against the live feed and stamp the date. If a cert is later pulled, the tag flips. It’s a freshness check on the same source, not a second independent opinion.
Three different questions. Purity (“how clean?”), identity (“is it the right molecule?”, a mass-spec test), and content (“did I get the labeled mg?”) are separate. A vial can be 99% pure and still be the wrong peptide, or the right peptide underdosed. We flag the measured dose against the label above; underdosing is the most common real fraud.
Who submitted the sample matters. Most of these are vendor-submitted — the seller chose which vial to send, so one good certificate doesn’t prove every batch is the same. The gold standard is a blind test, where a buyer sends a vial they bought as a normal customer. Same label doesn’t prove same product; same batch number doesn’t prove same batch.
