Semax / Selank price per month: $225, or $183/mo on 6 months
The short answer
Semax / Selank costs $225 a month at Peptides.build, $199/mo on the 3-month plan, or $183/mo on the 6-month plan ($1,099 billed once), prescribed by a licensed US provider and compounded by a licensed 503A pharmacy as one injectable blend, shipped already mixed. Semax alone is not offered here. The HHS peptide policy covers Semax only on its own as a nasal spray, so this blend is outside it.

Semax / Selank, prescribed and pre-mixed
Why the form matters for Semax
- Semax alone, by nasal spray, is one of the six peptides in the HHS policy of October 28, 2026. Peptides.build does not offer Semax alone.
- Selank is not listed in the HHS policy at all.
- The Semax / Selank blend is outside the policy, because the policy covers single-ingredient products and Semax only intranasally. It is still prescribed here by a licensed provider after an intake.
- Research sprays and vials are labeled not for human use, whatever the form. Is Semax legal?

What regulators say about peptides like Semax and Selank sold "for research use only"
These are their words, not ours. Each quote links to the official source.
“Injectable drug products can pose risks of serious harm to users. Injectable products are delivered directly into the body, sometimes directly into the bloodstream, and therefore, bypass some of the body's key defenses against toxins and microorganisms.”
“Despite statements on your product labeling marketing your products for "Research Use Only," … your products are intended to be drugs for human use.”
“[They can] contain contaminants, such as solvents, heavy metals, particles (fibers, glass, plastic), or microbials (bacteria, fungi, endotoxins).”
“This type of labelling does not make these products legal or exempt from regulatory requirements.”
HHS gave the same reason for its October 28, 2026 peptide policy: to pull patients away from research-use-only peptides supplied by foreign manufacturers. Read our HHS policy explainer.

FAQ
How much does Semax peptide cost?
Peptides.build does not offer Semax alone; the Semax / Selank blend is $225 a month or $183/mo on 6 months. Elsewhere, Pepti lists injectable Semax alone at $229 per month, and Rx Peps Direct lists a Semax nasal spray at $125 spray + $39 review + $15 shipping, every order.
How much is Semax / Selank per month?
$225 month to month at Peptides.build, $199/mo on 3 months or $183/mo on 6 months, with the provider review, compounding and shipping included. Pepti publishes $259 per month for its injectable blend.
How much is Selank nasal spray?
Rx Peps Direct prints $150 spray + $39 review + $15 shipping, every order for a prescribed Semax/Selank spray, and lists Selank alone as a spray too. Peptides.build prescribes the pair as an injectable blend, not a spray.
Is Semax available in the US?
Not as an FDA-approved drug. Under the HHS policy of October 28, 2026, licensed 503A pharmacies may compound Semax free base for a prescription, on its own and only as a nasal spray. Peptides.build does not offer Semax alone; it offers the Semax / Selank blend, which is outside the policy.
Can I buy Semax over the counter?
No. Semax sold without a prescription is labeled for research use only. A prescribed version needs a licensed provider and a licensed pharmacy.
Why is research Semax / Selank cheaper?
American Peptides lists $70 per vial for a powder vial and $90 ($63 in a sale ending November 1) for a spray, both labeled not for human use: no prescriber, no pharmacy label, and for the vial, you mix it yourself.
Can I pay over time?
Yes. Klarna, Afterpay and Affirm are offered at checkout, so a 3- or 6-month plan can be split into smaller payments.
Is Semax / Selank FDA-approved?
No. Neither Semax nor Selank is an FDA-approved drug in the US, and compounded medications are not FDA-approved.
Tired of reconstituting?
A licensed US provider reviews a short online intake. If a prescription is appropriate, a licensed US 503A pharmacy fills it and ships it cold-chain, already reconstituted and labeled with the concentration.
