Semax pricing FAQ
What is the cheapest Semax right now?
Peptide Pros currently lists Semax at $1.94 per mg (Semax 30mg, $58.25), the lowest of the 42 vendors we compare. The median is $4.50 per mg, so shopping around can save a lot.
How much does Semax cost per mg?
Across 42 vendors, injectable Semax ranges from $1.94 to $14.00 per mg, with a median of $4.50. Larger vials generally cost less per mg, which is why we normalize every listing to a price per milligram.
How much does a 10 mg vial of Semax cost?
A 10 mg vial of Semax costs between $22.00 and $85.00 across 29 vendors, with a median of $49.99. The cheapest is Bio Pepz at $22.00.
Which Semax vendors publish a COA?
44 of the 52 vendors listing Semax say they publish certificates of analysis (COAs). A COA is the vendor’s own claim and can be copied or re-dated, so we also show independent test ratings (Finnrick) on each vendor page where they exist, and let you filter to “COA claimed” vendors.
Does Semax come in forms other than injectable vials?
We also track sprays listings for Semax. They are priced per mg of active ingredient too, but usually cost more per mg than lyophilized vials. Use the form filter above to compare them.
Is there human research on Semax?
PubMed lists 209 papers on Semax: 1 randomized controlled trial, 5 human clinical studies and 145 animal or lab-only studies, plus 0 registered clinical trials. We grade the evidence base as “Moderate”: At least one randomized trial or a meaningful body of human studies, but not a deep trial base. This describes how much research exists, not whether it works.
Is Semax legal and safe to use?
Semax is sold for laboratory research use only. PeptideComps compares prices and does not give medical advice, and we can’t vouch for any product’s quality or legality — check the rules where you live.
