Sermorelin is the 1-29 fragment of growth hormone releasing hormone and was marketed as a medicine for years, primarily in paediatric growth hormone deficiency diagnosis. Its stimulation profile is well documented.
It is comparatively unstable in solution and is one of the products where a supplier's guidance on reconstitution and refrigeration correlates strongly with whether buyers report consistent results.
Three things move the Sermorelin price you see in the table above: how much active material a 5mg vial actually contains once excipients and salt content are accounted for, whether the supplier funds independent analysis on every batch rather than once a year, and how the vial is packed and shipped. Degradation after reconstitution is the usual complaint, and it reflects handling rather than the purity of the delivered powder. Compare price per milligram rather than price per vial, and discount any listing whose certificate is undated, unsigned, or tied to a different batch number than the one on the label.
Every supplier in this table is scored independently, and no vendor can pay to appear, move up, or have a poor result removed. We build a score out of ten from four weighted inputs: published third-party analytical documentation and how completely it covers the catalogue, identity verification of the company behind the website, the volume and consistency of moderated customer reviews collected through CheckALab, and operational signals such as dispatch reliability, stock accuracy and complaint handling.
For Sermorelin specifically we weight the documentation input according to how the compound fails: degradation after reconstitution is the usual complaint, and it reflects handling rather than the purity of the delivered powder. Suppliers publishing analysis that addresses that point score higher than suppliers publishing a headline purity figure alone. Reviews only count once they clear moderation, and no single review can move a score, so a burst of unusually positive or negative feedback cannot reposition a supplier. Scores are recalculated as new certificates, reviews and delivery data arrive.
The lowest headline price is rarely the best value. Compare price per mg rather than price per vial, check whether a batch-matched certificate of analysis is published, and factor in delivery. A cheap vial with no third-party testing behind it is not a saving.
Kensington Labs currently sits at the top of this table at £35 for a 5mg vial, and holds a CheckALab score of 9.43/10.
Tracked prices run from about £35 to £50 for a 5mg vial, depending on supplier, batch and purity documentation.
No. Prioritise suppliers with published third-party certificates and ID verification, then compare price per mg between those.
