research market · not for human use
These vendors sell compounds as research chemicals. Most are not FDA-approved.
Prices are each vendor’s listed price before shipping, unless a verified code is marked as included. Some outbound links are affiliate links and PeptideTech keeps a fee from sellers on checkout orders; neither affects grades or scores, or order apart from the labelled featured partner. PeptideTech does not test products. Certificates of analysis are the seller’s or the lab’s documents, attributed to them, and PeptideTech does not verify them unless a specific record says so.

- Package. Every row is a single vial (1 vial · 5mg labelled); multi-vial packs, kits and bundles are left off this comparison.
- Price scope. Each vendor’s listed item price in US dollars for the US market, before shipping and sales tax, which its checkout sets. A code is deducted only when its discount was verified in a cart. These are research-use package prices, not clinic, prescription or monthly programme costs.
- Current or historical. A price is current when its source was read in the last seven days; historical rows are older listings, kept with their date and left out of the lowest price and the structured data.
How offers are selected
- Every row is one exact package: 5mg, one form, US market, US-dollar price as the vendor lists it.
- Vials, multi-vial packs, bundles, pens, sprays and blends stay in separate comparisons; kits and subscriptions are left out.
- Offers are ranked by displayed price; a code is included only when its discounted price was verified in a cart. A referral code is not a confirmed discount.
- A price is current when its source was read in the last 7 days; older listings stay visible as historical and are excluded from the lowest price. Read each offer’s source date, stock, currency and market.
- A catalogue name or alias (a vendor code name) is the seller’s claim: check it against the product specification and the lot report.
- Grades come from lab documents, business records and service terms, scored the same way for every vendor; no vendor can pay for a grade or rank.

is Semax legal?
This page compares research-labelled listings for Semax.

short answers
Semax questions
How much does Semax cost?
Semax 5mg costs from $39.99 across 1 vendor with a current price. The cheapest in-stock offer is Cenexa Labs at $39.99 ($8.00/mg), observed Nov 6, 2026. Other sizes (10mg, 30mg) are listed in the price-by-size table. Across every size, current in-stock listings run from $2.50/mg (30mg at Amino USA) to $8.00/mg (5mg at Cenexa Labs). These are US-dollar item prices for research-use packages, before shipping, sales tax and unverified codes; they are not the monthly cost of a clinic or prescription programme.
Where is the cheapest place to buy Semax?
Cenexa Labs is the only vendor with a current price for Semax 5mg, at $39.99, with code PEPTECH available through our link but not deducted from the listed price. “Cheapest” uses the displayed price, including a code only when its discounted price is explicitly verified, and excludes shipping.
Is the Semax 5mg price for one vial or several?
One. Every 5mg offer compared here is a single vial labelled 5mg, so its price per mg is the item price divided by 5mg. Multi-vial packs, kits and bundles are left off the comparison, because a pack is a different unit from one vial. Check the selected option on the vendor’s page before ordering. The listings compared here are research-use-only products sold for laboratory research, not medicines for human use.
How is the Semax 5mg price per mg calculated?
Item price divided by the labelled amount: $39.99 ÷ 5mg = $8.00/mg for the cheapest current offer (Cenexa Labs, observed Nov 6, 2026). The figure uses the label, not a measured assay: a certificate’s purity or net-content result is reported separately and can differ from the label. Shipping, tax and unverified codes are not included.
What sizes of Semax are available?
Semax is sold in 3 sizes: 5mg, 10mg, 30mg. This page compares the selected package; availability differs by form, size and vendor.
Are the Semax prices and discount codes current?
Each offer shows the date its price was last observed at the vendor (newest for 5mg: Nov 6, 2026); loading the page does not check vendors again. Automated sources run on a schedule and other sources are checked by hand, so dates differ by vendor. A listing not seen for 7 days is marked historical and excluded from current prices. A code is deducted from a price only when its discount was verified in a cart; for 5mg, 1 offer carries a code shown before its discount.
Which Semax coupon codes work?
Code TECH10 was accepted in a recorded cart check. Listed prices remain before this coupon; confirm eligibility for the selected items in your cart. Code PEPTECH was accepted in a recorded cart check. Listed prices remain before this coupon; confirm eligibility for the selected items in your cart.
Is Semax FDA approved?
A product-specific regulatory review has not been completed. This catalogue entry does not establish authorization, lawful sale or import eligibility in any country; check the exact product and destination with the relevant regulator. Every listing on this page is a research-use-only product, whatever the status of any approved medicine with the same active compound.
Has Semax been tested in clinical trials?
No ClinicalTrials.gov registration listing Semax as an intervention was matched (checked October 1, 2026). This is a gap in matched records, not proof that no study exists. PubMed indexes 4 selected human studies in which participants received Semax, most recently “[The efficacy of semax in the tretament of patients at different stages of ischemic stroke]” (Zhurnal nevrologii i psikhiatrii imeni S.S. Korsakova, 2018). The listings compared here are research-use-only products sold for laboratory research, not medicines for human use.
Is Semax legal to buy?
A research-labelled listing does not establish legal eligibility in every jurisdiction. Product status, purpose, import rules and destination matter. Review the jurisdiction-specific sources in the reference notes; PeptideTech does not provide a worldwide legality determination.
Can I buy Semax over the counter?
PeptideTech has not completed a product-specific regulatory review for Semax, so this page does not state its prescription status. The listings compared here are research-use-only products sold for laboratory research, not medicines for human use. Whether a product may be bought, imported or used depends on the jurisdiction, the exact product and its purpose; PeptideTech does not sell products or provide a legality determination.
