White-label and private-label options
Generic, white-label, or private-label fulfillment. See the white-label vs. private-label guide.
Packaging, shipping, and storage
Semax ships as lyophilized powder in sealed amber vials with tamper-evident closure. Shock-protection packaging is standard. Cold-chain shipping is available. The lyophilized form is stable at room temperature for short-duration transit.
Compliance and labeling
Semax is supplied to verified B2B partners exclusively for research use under strict research-use-only labeling. Resellers are responsible for maintaining research-use-only labeling, the FDA disclaimer, and compliance with state, local, and international regulations governing research-peptide distribution.
FAQ
What is the relationship between Semax and ACTH?
Semax is a synthetic heptapeptide whose sequence (Met-Glu-His-Phe-Pro-Gly-Pro) is derived from a fragment of the natural adrenocorticotropic hormone (ACTH 4-10) with additional structural modifications. The synthetic version was developed in Russian academic research and has an established research literature.
What pack sizes are available?
Standard pack sizes are 5 mg and 10 mg lyophilized vials. Custom pack sizes available through private-label fulfillment.
What’s the standard purity?
99%+ verified by HPLC and confirmed by mass spectrometry. The COA ships with every batch.
Are sample COAs available?
Yes. Verified partners can request COAs from recent batches before placing an order.
How is Semax stored?
Lyophilized at −20°C for long-term stability. After reconstitution, store at 2–8°C and use within the documented stability window appropriate to the research application.
