Peptide Serum reference: Member unit price (USD), available with verified paid PRO membership; excludes shipping and applicable taxes. Read from catalog: Oct 23, 2026 04:30 UTC. 1 x 10 mg = 10 mg total.
Source: PeptideSerum-exact-size-market-comparison.xlsx. One selected single-container price per supplier domain, for the same labeled vial size and formulation. Blends match recorded component amounts. The arithmetic mean uses the first ten selected supplier prices in recorded Google discovery order, or the true smaller sample when ten could not be found. No size scaling, mg-to-IU conversion, pack discount or minimum price range is substituted.
The green percentage, when shown, compares the member price for every visitor: (recorded exact-size market average minus Peptide Serum member price) divided by the recorded market average. Unrounded values are used and the percentage is rounded down to one decimal. It is omitted when the member price is equal to or above the reference or the refreshed snapshot cannot be confirmed. Member pricing requires verified paid PRO membership.
These are dated price observations, not live available supplier offers. Shipping is excluded. Supplier tax treatment is retained as recorded and can differ. Memberships, clinical qualifications, ancillary supplies and availability can affect comparability; source notes retain these limitations. Some observations were sold out. Seller domains may be correlated through one manufacturer. This is not a revenue-ranked or complete-market survey.

Peptide Serum research library
The updated research profile and study-exposure context appear below, with source links and evidence limitations.
Selank is a tuftsin-derived peptide with small human anxiety studies and preclinical mechanistic research. Those findings do not establish broad cognitive enhancement or comprehensive long-term safety.
The research molecule extends the tuftsin sequence with Pro-Gly-Pro. Modified derivatives or differently formulated products need their own evidence.
Selank and Semax are different molecules, despite similar names and overlapping marketing categories.
The literature should not be described as entirely preclinical: small patient comparisons exist. However, their limited reporting, active comparators and combination designs constrain the conclusions. Rodent neurotransmission studies address mechanism rather than demonstrating treatment benefit in people.
| Study and design | Finding | What it does not establish |
|---|---|---|
| Selank compared with medazepam in anxiety and neurasthenia
Small comparative clinical study indexed as randomized Reading scope: PubMed abstract excerpt |
The abstract describes similar anxiolytic effects and additional reported symptom differences. | The retrieved abstract provides limited detail on masking and effect size; active-comparator similarity does not establish broad equivalence or long-term safety. |
| Selank added to phenazepam in anxiety disorders
Comparison of 30 monotherapy patients with 40 combination-treatment patients Reading scope: PubMed abstract |
The authors reported earlier changes on a symptom scale and fewer selected undesirable effects with the combination. | It does not isolate standalone Selank effects, and the abstract does not describe a blinded randomized allocation. |
| Selank and neurotransmission-related gene expression
Rat frontal-cortex gene-expression experiment Reading scope: Full-text methods and results sections |
Selank and GABA produced overlapping and differing changes in measured transcripts. | Transcript changes do not demonstrate receptor binding, patient benefit or freedom from dependence. |
For the differences between a mechanism, a biomarker and a clinical outcome, see the evidence-reading guide.
Claims such as non-addictive or free of withdrawal require appropriate follow-up, not simply comparison with a benzodiazepine in a small study.
Changes in neurotransmission-related gene expression can suggest mechanisms. They do not establish that a molecule behaves identically to GABA or treats every anxiety disorder.
These studies do not characterize uncommon harms, long-term effects or all interactions. Findings from supervised combination treatment cannot validate unsupervised combinations or a different delivery route.
Keep the exact preparation and administration route attached to each study. Rodent intranasal exposure and clinical combinations cannot supply a generalized human injection or cognitive-enhancement regimen.
Match any reported amount or concentration to the exact material, route, population and duration in the original experiment. Read the guide to mass, volume and concentration for the meaning of common units. A calculation cannot establish an appropriate treatment or validate an untested formulation.
Confirm ordinary Selank sequence and any terminal modification. A report for tuftsin, Semax or a named modified Selank derivative does not establish ordinary Selank identity.
Keep the clinical evidence and the supplier evidence separate. Use the report-verification steps to check the issuer and the batch questions to connect a tested sample with the product offered. Compare prices using the delivered-cost method rather than an isolated discount or purity percentage.
Peptide Serum operates a store as well as this research library. The supplier directory contains imported seller information; a listing is not laboratory certification. Read how this library is prepared and evaluate the documentation for the exact lot offered. A seller rating does not establish clinical safety or effectiveness.
Yes. The small comparisons summarized here are relevant, but are not a large, replicated, placebo-controlled evidence base for every promoted use.
No. Both groups received phenazepam; the study examines adding Selank under its particular conditions.
No. Shared downstream observations are not chemical identity or proof of an identical mechanism.
This companion to the Selank research profile explains how to interpret experimental quantities. It provides no personal-use regimen.
Keep the exact preparation and administration route attached to each study. Rodent intranasal exposure and clinical combinations cannot supply a generalized human injection or cognitive-enhancement regimen.
Find the tested material, formulation, route, study population, comparison group and observation period in the original paper. Exposure in a cell system or animal model does not supply a human starting amount, schedule or route.
Mass describes an amount of material; concentration describes that amount per final solution volume. One milligram equals 1,000 micrograms. Neither a vial label nor arithmetic establishes identity, stability, sterility or an appropriate use.
Read the units reference and the study summaries and their limitations. Use the original methods for the precise experimental conditions; do not transfer a reported amount between different materials or study models.
The main profile links the selected primary sources, distinguishes the study designs and explains what the findings cannot show. A trial registration is a research plan, not a published result.
