Compare Semaglutide vendors by PSR score
Every vendor we track that carries Semaglutide (51 in all), ordered by PSR score, the published vendor score. For laboratory research use only: this compares vendors and their certificates, and says nothing about dosing or effects.
Price per mg is matched at 10mg, the size most of these vendors sell, so vials compare like for like. Prices as checked October 22, 2026 to November 6, 2026. Certificate status is for this product only. Affiliate status never affects scores or order (how we keep it separate). 20 vendors marked “Fails testing gate” do not meet our testing gate.

Lowest first; vendors that do not sell 10mg follow, by their own lowest price per mg. Cheapest is not the same as best: check the certificate and the PSR score beside each price. Back to the PSR score order.

Who has the best Semaglutide?
In our 2026 audit, Amino Club is listed first for Semaglutide: its certificate for Semaglutide scores 9.5/10 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 Semaglutide per mg?
The lowest recorded price per milligram for Semaglutide 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 Semaglutide 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 Semaglutide; 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.
