Before you order Sermorelin
- Look at the shop's grade for Sermorelin, not its average. Shanghai Sigma Audley SSA has the most Sermorelin tests (8); a shop with one or two tests has not shown it is consistent.
- 96% of these vials were bought and sent in by customers; the rest were sent by Finnrick or by the shop itself. Results from vials a shop chose to send are the weakest evidence.
- 6 labs tested them, mostly Krause Analytical and BTLabs. Ask for the certificate for your batch and check it on the lab's own site.
- Run the vendor checklist before paying, and read how the grades work.
