I got some from TP peptide for $110 for 10mg not that long ago, seems to be adamax, compared to what I originally bought from SSA. No COA, but I never found anyone with test results for adamax despite looking quite hard. Communication left a lot to be desired, but it did arrive. Found them on p e p ch at ( cannot write name as site changes it to data mining site )
I found many of the descriptions of adamax and semax to be confusing . My understanding is adamax has the NA modification at one end and an amidate at the other of the base peptide semax, to reduce degradation and improve BBB penetration, but several sites advertise na semax or na semax amidate much cheaper than adamax, and as far as I know from the chemistry na semax amidate is adamax.
