On this pair the paperwork matters more than the chemistry, and it is worth reading before ordering either. Semax is a defined heptapeptide, the ACTH 4-7 core carrying a Pro-Gly-Pro tail, C37H51N9O10S at 813.9, CAS 80714-61-0. Every line of its certificate can be checked against something: a measured mass against a calculated one, a purity as an area percentage, and the sulfur in that formula is the methionine whose sulfoxide is the first impurity to grow in an ageing vial. Adamax has no CAS number, no published formula and no calculated mass, because its structure is not authoritatively established. Its own sheet says so, and identity on its certificate is therefore stated against the batch rather than against a reference figure. That is not a defect in the batch and it is not being hidden here: it is a limit on what any certificate for this line can tell you, and it belongs in the price you are willing to pay. Both are offered in 5 and 10 mg vials.

Are Adamax and Semax tested to the same specification?
Yes: purity not less than 98.0 percent by RP-HPLC, identity by mass, water content, net content within 5 percent of label, and a retest date, with a certificate of analysis per batch. What differs is what each certificate has to look for, which is set by the molecule and described on each compound’s own page.
