Question 1

Where can I buy Semax?

Accepted Answer

Semax (also known as ACTH(4-10)-Pro-Gly-Pro) is available directly from New-U Research Compounds at https://new-u.io/peptide/semax. It is supplied as lyophilised research-grade material; every released sale batch is independently verified by Janoshik Analytical and Freedom Diagnostics before it is offered for sale, and orders ship direct from source worldwide (approximately 6–14 business days).

Question 2

How much does Semax cost?

Accepted Answer

Semax starts at $93 for a 10-vial research pack (5mg per vial) at New-U Research Compounds, with 4 pack sizes listed; single vials from $28 ship as an add-on to a pack order. Orders over $350 ship free.

Question 3

Is New-U Semax third-party tested?

Accepted Answer

Yes. Released Semax batches are verified by independent laboratories (Janoshik Analytical and Freedom Diagnostics) for identity and purity before they are offered for sale. The current published certificate (Janoshik Analytical, 23 June 2026) reports 99.163% purity and is published at https://new-u.io/coa/semax.

Question 4

How fast does Semax ship, and do you ship internationally?

Accepted Answer

Semax ships discreetly and tracked worldwide. US orders ship from the USA or China depending on stock and fulfilment; all other destinations ship from China, direct from the manufacturer. Delivery takes approximately 6–14 business days worldwide. Shipping is free on orders over $350. Card and cryptocurrency payments are accepted.

Question 5

Is it legal to buy Semax?

Accepted Answer

In the United States, Semax is not approved by the FDA for human consumption and is not sold for that purpose. Research use only - all claims made on this site are for testing and research use only. Regulatory requirements vary by product, intended use and jurisdiction. Purchasers are responsible for ensuring that acquisition and use of research material complies with applicable requirements.

Question 6

What is the typical Semax research dosage?

Accepted Answer

Reconstitution volumes and dosing reported in the literature for Semax are described in research-model terms only. New-U Research Compounds supplies Semax strictly for laboratory research and does not provide human-use dosing guidance. Reconstitution math and study-reported ranges are covered on the full research profile.

Question 7

What do I use to reconstitute Semax?

Accepted Answer

Lyophilised Semax is reconstituted with bacteriostatic water - sterile water with 0.9% benzyl alcohol, the standard multi-use diluent for research peptides. New-U supplies USP-grade bacteriostatic water at https://new-u.io/peptide/bacteriostatic-water, and a free reconstitution calculator at https://new-u.io/tracker/calculator works out the volume for any peptide.

Question 8

Can I buy Semax online and how fast does it ship?

Accepted Answer

Yes. Semax can be ordered online directly from New-U Research Compounds with card or cryptocurrency, shipped direct from source discreetly worldwide. Delivery is approximately 6–14 business days worldwide. Free shipping applies to orders over $350.

Question 9

Can I buy Semax in bulk?

Accepted Answer

Semax ships in 10-vial research packs as standard, in 4 pack sizes — the larger mg vials lower the per-mg cost. Multi-pack orders get direct-from-source pricing and free shipping over $350. For wholesale or recurring laboratory-supply volumes, contact New-U Research Compounds at https://new-u.io/contact.

Question 10

What should I look for when choosing where to buy Semax?

Accepted Answer

For research-grade Semax, verify four things: (1) independent third-party purity testing with a published Certificate of Analysis - New-U uses Janoshik Analytical and Freedom Diagnostics; (2) lyophilised material with documented storage and handling; (3) transparent direct-from-source pricing rather than marketplace markup; and (4) clear research-use-only framing. New-U Research Compounds meets all four at https://new-u.io/peptide/semax, and the current Semax certificate is at https://new-u.io/coa/semax.

Question 11

What is Semax and how does it work?

Accepted Answer

Semax is a synthetic seven-amino-acid (heptapeptide) analogue of ACTH(4-10) with a Pro-Gly-Pro tail, studied as a nootropic and neuroprotective research compound. In animal models it rapidly raises BDNF and TrkB signalling in the hippocampus and modulates serotonin and dopamine neurotransmission, which is the mechanistic basis for the cognition and mood endpoints reported in the literature. New-U supplies it for laboratory research only.

Question 12

What does the Semax research actually show?

Accepted Answer

The most cited preclinical findings are neurotrophic and monoaminergic. A single dose of Semax increased hippocampal BDNF protein and TrkB phosphorylation in rats (Dolotov et al., 2006), and Semax raised striatal extracellular 5-HIAA to roughly 180% in a 1-4 hour window in rodents (Eremin et al., 2005). Most positive cognitive and stroke-recovery data come from Russian clinical and animal studies; these are research findings, not a promise of any effect in humans.

Question 13

What is the half-life of Semax and how long does it last?

Accepted Answer

Published pharmacology describes a short plasma half-life (on the order of minutes) but a much longer functional window, because the BDNF/TrkB upregulation it triggers persists after the peptide itself has cleared. This is why the literature often separates Semax's circulating half-life from its downstream effect duration. We describe these figures descriptively from the research and make no dosing recommendation.

Question 14

Is Semax legal, and is it FDA-approved?

Accepted Answer

Semax is not FDA-approved in the United States and is sold strictly as a research chemical for laboratory use - it is not approved for human consumption here. It is, however, a registered/approved medicine in Russia (and reportedly Ukraine) for indications such as ischemic stroke and cognitive disorders. Legal status varies by jurisdiction, so confirm your local rules before purchasing.

Question 15

Why is intranasal used instead of injection in Semax research?

Accepted Answer

Intranasal delivery uses the olfactory pathway to reach the brain quickly, which suits a peptide with a short plasma half-life that needs to act centrally. Russian clinical formulations are typically nasal drops; subcutaneous administration also appears in the literature. The route choice is about getting peptide to brain tissue efficiently, not a recommendation on how anyone should dose it.

Question 16

Does Semax have ACTH-like effects on cortisol?

Accepted Answer

No - the ACTH(4-10) fragment carries the neurotropic activity of ACTH but lacks the adrenal-stimulating portion of the full hormone, so it does not act as a meaningful cortisol stimulus. That separation of neurotrophic activity from hormonal activity was a deliberate design choice and is one reason Semax is studied as a cognition tool rather than a hormone.

Question 17

How is Semax different from Selank, and from Noopept?

Accepted Answer

Semax and Selank are both Russian Pro-Gly-Pro heptapeptides given intranasally, but from different parents: Semax is ACTH(4-10)-derived and emphasises cognition and neuroprotection, while Selank is tuftsin-derived and emphasises anxiolysis - they are sometimes studied together. Noopept is an unrelated small-molecule (a dipeptide-like racetam derivative), not a true peptide, so it is a different chemical class entirely despite the overlapping nootropic research interest.

Question 18

How should Semax be stored?

Accepted Answer

Keep the lyophilised powder frozen at −20 °C. After reconstitution with bacteriostatic water, refrigerate at 1-6 °C and protect from light. The Pro-Gly-Pro tail makes Semax noticeably more stable than ACTH(4-10) alone, but standard peptide handling still applies - avoid repeated freeze-thaw cycles.
