Sermorelin: Frequently Asked Questions

Who has the best Sermorelin?

In our 2026 audit, Amino Club is listed first for Sermorelin: its certificate for Sermorelin scores 9.0/10 on our lab rule, and its published vendor score is 8.02/10. The full ordered table is on this page.

What is the cheapest Sermorelin per mg?

The lowest recorded price per milligram for Sermorelin in our audit is the "Best $/mg" figure at the top of this page, and every carrier's price per mg is in the table. Cheapest is not the same as best: the table is ordered by certificate and vendor score, not by price.

How do you rate Sermorelin vendors?

Ordered by the lab-rule score of each vendor's certificate for this product (out of 10), then by the vendor's published score, then alphabetically. The certificate score is the same lab rule that builds each vendor's lab sub-score, applied to that vendor's certificate for Sermorelin; the vendor score is the published overall score. Price per mg is shown but does not change the order. See our methodology for the lab rule.
