What Semax is
Semax is a synthetic analogue of ACTH 4-10 with the hormonal activity removed, registered as a medicine in Russia and studied there in ischaemic stroke and cognitive function, with a body of literature largely inaccessible in English.
Its close relative Selank shares the same research tradition, and the two are often stocked and confused together.
What the evidence base looks like
There is a real published record behind this compound, spread across animal work and a smaller amount of human data, but not enough controlled evidence to support confident claims.
Our library records roughly 88 relevant publications for Semax and grades the evidence as moderate. That grade describes the weight of research, not a judgement about safety or effect, and it is reviewed as new work is published.
Supplier quality: what to check on Semax
N-acetylated and plain variants are both sold as Semax, and they are not the same product.
The practical checklist is the same on every product but weighted differently here: a batch-matched certificate of analysis, an identity method appropriate to this molecule rather than purity alone, clear peptide content per 5mg vial, and a supplier that will answer a technical question before taking payment.
Typical UK pricing
The lowest price we currently track for a 5mg vial is £24.95, against a market median nearer £35. Compare on price per milligram rather than per vial, because vial sizes across suppliers are rarely identical.
A listing well below the tracked low is worth investigating rather than celebrating. On this compound the cost of doing it properly is largely analytical, and that is the first thing an unusually cheap supplier stops paying for.
