Semax: price, documentation and dispatch in Colombia
Semax appears in the catalog in a single presentation, a 10 mg vial, within Nootropic Peptides and Neuromodulators. Technically it is a heptapeptide derived from the 4-7 fragment of corticotropin, the same hormone whose complete 39-amino-acid sequence exists in this catalog under the name ACTH 1-39. This page develops that relationship, compares Semax's classification with Selank's — the category's other heptapeptide — explains what to state when quoting its presentation, and describes what Janoshik Analytical certifies for each batch. All material ships exclusively for research and institutional B2B quotation.

The 4-7 fragment of corticotropin as a starting point
Semax's technical sheet describes it as a heptapeptide derived from the 4-7 fragment of corticotropin. That detail has a direct reference within the same catalog: ACTH 1-39 is the complete 39-amino-acid sequence of that same hormone. Semax corresponds only to a specific portion of that sequence — amino acids 4 through 7 — not to the complete molecule.
This relationship is a structural classification, verifiable in both references' technical sheets. It does not imply that Semax shares function with the complete corticotropin molecule; it only describes which portion of which sequence it derives from, as stated in the catalog.
Semax and Selank: two heptapeptides, two distinct origins
Within Nootropic Peptides and Neuromodulators, Semax shares with Selank the trait of being a heptapeptide: seven amino acids long. The declared origin, however, is different: Selank is a tuftsin analog, while Semax derives from the 4-7 fragment of corticotropin. They are two different molecular families that happen to coincide in chain length.
The category also includes DSIP (a nonapeptide associated with delta sleep), Cerebrolysin (a peptide hydrolysate of porcine origin), Orexin A and B, P21, and PE-22-28. Nine references in total, grouped by the research system — neuronal signaling — each with its own structural classification.
Semax's 10 mg presentation: what to state in the quotation
Nootropic Peptides and Neuromodulators groups nine references: Selank, DSIP, Cerebrolysin, Orexin A and B, P21, PE-22-28, Pinealon, and Semax. The current figure for the 10 mg vial of Semax is read from the pricing block on this same page.
That figure is confirmed in writing in the quotation, without assuming it matches another reference in the same category or a prior inquiry. This page's text does not repeat the number so that it never falls out of date relative to the price the catalog shows in real time.
What Janoshik certifies, and what no COA certifies
Janoshik Analytical signs the certificate for each Semax batch: high-performance liquid chromatography (HPLC) for purity and mass spectrometry (MS) for identity. That pair of methods is the entire documentary backing that exists; no certificate in this catalog attests to a use or an indication, only what the material is and how pure it is.
That certificate is handled on request and subject to documentary availability. The CAS number, molecular formula, molecular weight, and exact purity percentage remain unfilled here: they appear as visibly pending in the technical block and are resolved against the document of the batch being dispatched.
10 mg lyophilized powder: documented handling and storage
Being declared by mass, the 10 mg vial corresponds to lyophilized powder, with declared origin in the United States. Shipping cost is confirmed at the time of quotation and stays separate from the price of the material; see the site's shipping information for current rates to Bogotá and the rest of the country. Outside Colombia, this reference ships to 5 countries (Costa Rica, Ecuador, United States, Mexico and Puerto Rico), from US$57; the rate for each country is listed on the site's international shipping page.
Storage follows the documentation applicable to the batch; when it specifies 2–8 °C and protection from light, that range should be available at the receiving institution before the package arrives, with the batch and presentation already logged internally.
Quotation, payment, and receipt: the sequence that leaves a trail
Selecting Semax does not trigger any charge: the request is registered first, then the quotation is confirmed with the payment method and total already defined, and the disbursement is coordinated at the end. It is best to file the proof of payment together with the order code so that later reconciliation does not depend on scattered messages.
Once the cycle is closed, the file can contain the quotation, the proof of payment, the dispatch confirmation, the receiving record, and the Janoshik COA if it was requested. This page goes no further than that documentary chain and Semax's classification as research material.
Frequently asked questions about Semax
What presentation is Semax available in?
A single 10 mg presentation. The list price appears in the pricing block on this page and is confirmed in the institutional quotation.
What relationship does Semax have with ACTH 1-39?
Semax derives from the 4-7 fragment of corticotropin; ACTH 1-39 is the complete 39-amino-acid sequence of that same hormone. They are two distinct catalog references.
What distinguishes Semax from Selank?
Both are heptapeptides, but of different origin: Semax derives from corticotropin and Selank is a tuftsin analog. The comparison is limited to their structural classification.
Who certifies Semax's identity and purity?
Janoshik Analytical, per batch, with HPLC for purity and MS for identity. The COA is handled on request and subject to documentary availability.
How is Semax stored?
As lyophilized powder, per the documentation applicable to the batch. If it specifies 2–8 °C and protection from light, that condition is built into the custody record.
How much does it cost to ship Semax to Bogotá or the rest of the country?
See the site's shipping information for current rates. The delivery time is confirmed at the time of quotation, based on the chosen destination. Outside Colombia, this reference ships to 5 countries (Costa Rica, Ecuador, United States, Mexico and Puerto Rico), from US$57; the rate for each country is listed on the site's international shipping page.
