Adamax vs Semax
Strength for strength, Semax costs less per mg at the two strengths both sell by the single box: at 5mg $0.908 per mg against $1.305 (XA5, ADA5), at 10mg $0.740 per mg against $1.156 (XA10, ADA10). Adamax is offered in 2 strengths (5mg to 10mg), Semax in 2 (5mg to 10mg); Semax has 1 on the shelf today, Adamax none (made to order, about four weeks).

What differs between Adamax and Semax
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. Its sheet gives a calculated mass for the measured one to be matched to, and the sulfur in that formula is the methionine, which can oxidise to the sulfoxide. 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 gives identity by ESI-MS with no calculated mass to match it to. That is not a defect in the batch, and it is not hidden here. Both are offered in 5 and 10 mg vials.

Questions
What is the difference between Adamax and Semax?
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.
Which is cheaper per mg, Adamax or Semax?
Strength for strength, Semax costs less per mg at the two strengths both sell by the single box: at 5mg $0.908 per mg against $1.305 (XA5, ADA5), at 10mg $0.740 per mg against $1.156 (XA10, ADA10).
Which comes in more strengths, Adamax or Semax?
Both are offered in 2 strengths. Every strength is a separate line with its own code, price and stock state.
Are Adamax and Semax made to the same specification?
In purity and net content, yes: both are supplied to purity not less than 98.0 percent by RP-HPLC and net content within 5 percent of label, and each certificate reports those with a measured mass: Adamax has no calculated mass, its structure not being established, so its measured mass has no calculated figure to be matched to; Semax’s is matched to its calculated 813.9. The retest date is on the batch record. What differs is each molecule’s own chemistry, described on its compound page.
