Synthetic ACTH-fragment neuropeptide
Synthetic ACTH-fragment neuropeptide, commonly studied alongside Selank.
Semax is a synthetic peptide derived from a fragment of adrenocorticotropic hormone (ACTH), modified to remove hormonal activity. Developed as a neuropeptide research tool, it is frequently studied alongside Selank. Supplied as lyophilized powder for laboratory research use.
ACTH(4-10) analog
Synthetic analog of an adrenocorticotropic hormone fragment.
Extensively studied nootropic
Among the most-referenced peptides in cognitive-research literature.
Lot-verified ≥99% purity
Independent HPLC verification per batch.
Batch-matched COA
Tied to your specific lot number.
Every batch passes four independent tests.
Lot-specific COAs. Failed batches are rejected — never shipped. You know exactly what's in the vial.
Identity
Peptide sequence verified.
Purity
≥99% confirmed via HPLC.
Sterility
Microbial contamination screened.
Endotoxin
LPS within research limits.
What researchers are saying.
Packaging is genuinely professional
Sealed, cold-packed, and clearly labeled. Everything about the presentation says they take handling seriously.
Same quality every single time
Multiple orders in and the consistency hasn't slipped once. Same professional packaging, same condition on arrival.
Support that actually knows their stuff
Had a storage question before ordering and got a detailed, knowledgeable reply within the hour. Not a script — real expertise.
Four orders deep, never disappointed
Reliability is everything to me and they deliver every time. Packaging and turnaround have been flawless across every order.
Issue resolved the same day
A carrier delay held up my order — reached out and they sorted it same day, no hassle. That kind of customer-first approach earns loyalty.
My go-to, order after order
I keep coming back because nothing about the experience changes — clean packaging, fast handling, responsive team. Consistency you can count on.
Everything you'd want to know.
Yes — each shipment includes a batch-matched Certificate of Analysis tied to your lot number.
Store lyophilized vials at -20°C, protected from light. Reconstituted vials at 2–8°C.
Everything researchers ask before ordering.
How fast does this ship?
Orders leave our United States facility within 24–48 business hours, with standard delivery in 2–5 business days. Tracking is emailed the moment your order ships, and shipping is free on orders over $200.
What’s included with each vial?
Every order ships with the lyophilized vial and its batch-specific certificate of analysis. Vials travel in plain, unbranded packaging with protective materials, labelled for research use only.
How is purity verified?
Every batch is tested by an independent third-party lab for identity, purity, sterility and endotoxins. Release requires ≥99% chromatographic purity, and any lot that fails is rejected rather than shipped.
How should this be stored?
Keep unopened vials cool, dry and out of direct light. For longer storage most compounds are best refrigerated or frozen — check the product page for compound-specific guidance and follow your lab’s own handling procedures.
What payment methods do you accept?
All major credit and debit cards, plus Apple Pay and PayPal. Payments run through encrypted gateways and card details are never stored on our servers.
What’s your return policy?
Every order is covered by our 365-day satisfaction guarantee. If something isn’t right, contact us within 365 days of your order and we’ll arrange a refund or a replacement.
Do you ship internationally?
Not currently. We ship to all 50 U.S. states from our United States fulfillment facility, with tracked delivery included on every order.
Are these products for human use?
No. Everything sold here is supplied strictly for in-vitro laboratory research by qualified professionals. These are not drugs, supplements, foods or medical devices, and are not for human or veterinary consumption.
