Common questions
Does PT-141 come with a certificate of analysis?
Yes. 1 third party certificate for PT-141 are published on this site, covering endotoxin, purity and sterility. Each one is the report as the testing laboratory issued it, not a retyped summary, and the most recent lot is 10mg · Feb 2026. Match the batch on your vial to the batch on the report.
What is the CAS number for PT-141?
1607799-13-2. It is printed in the specification table on this page so it can be checked against your own records before ordering.
How should PT-141 be stored?
Refrigerate (2-8 deg C) Lyophilized powder is the stable form; once reconstituted, a solution is far more fragile and should be aliquoted rather than repeatedly frozen and thawed.
What purity is PT-141?
>=99% by HPLC. The released figure for any given lot is on that lot's certificate rather than taken from this page, because purity is a property of a batch and not of a product line.
Is PT-141 intended for human use?
No. This is sold for laboratory research use only. It is not a drug, not a supplement, and not approved by the FDA for human or veterinary use. We do not provide dosing, administration, or protocol guidance, by phone, by email, or through the assistant on this site.
