Compounded Semax

Semax was removed from the FDA's Category 2 bulk-substances list on April 15, 2026. The Pharmacy Compounding Advisory Committee (PCAC) reviewed compounding eligibility on 2026-07-23. Until that ruling is published and applied, 503A pharmacies cannot lawfully compound Semax from bulk substances.

Why this directory exists

Pepticker primarily tracks research-use peptide pricing across registered research-chemical vendors. The 503A compounding-pharmacy channel is a different regulatory universe — it requires an individualized prescription, a licensed pharmacist, and a substance that is either FDA-approved or on the 503A bulk-substances list. The April 15, 2026 Category 2 removal disrupted that pipeline for the seven peptides on this directory, and PCAC is the body that decides whether it gets restored.

This page exists so that within 72 hours of a favorable PCAC ruling, a verified directory of US 503A pharmacies that actually compound Semax can be published here. We do not pre-list pharmacies; the directory only goes live with verified, currently-active entries.

Current research-only access

Semax is a seven-residue ACTH(4-7) analog with a Pro-Gly-Pro stabilizing tail, developed in Russia and used clinically there for stroke and cognitive indications. The Russian clinical literature is substantial; Western trial-grade evidence is sparse, and the peptide is unapproved by FDA, MHRA, Health Canada, and TGA.

Live research-use vendor pricing for Semax is tracked on the standard Pepticker PDP: Semax price comparison.

Current 503A status

Semax was removed from FDA Category 2 on April 15, 2026, pending PCAC review on July 23-24, 2026. 503A bulk compounding is not authorized in the interim. Research-only vendor purchase is presently the only legal route in the US.

What changes if PCAC votes favorable

Favorable ruling pathway

A favorable PCAC vote returns Semax to the 503A bulk-substances pipeline. State-licensed 503A compounding pharmacies that hold the appropriate non-sterile (or sterile-injectable, depending on dosage form) facility licensing would once again be able to dispense patient-specific prescriptions written by a licensed prescriber. In that scenario, this page will publish a verified directory of pharmacies that actually carry compounded Semax, including state of license and any telehealth-clinic relationships. Listings will be sourced from state board of pharmacy records and direct verification — not vendor self-reporting.

What changes if PCAC votes unfavorable

Unfavorable ruling pathway

An unfavorable PCAC vote keeps Semax off the 503A bulk-substances list. In that scenario the only legal channels in the United States remain (a) research-only purchase from registered research-chemical vendors and (b) any FDA-approved finished drug that happens to contain Semax as an active ingredient (none currently exist for the peptides in this directory). This page would shift to a regulatory-history explainer rather than a pharmacy directory, and the research-use price comparison at /peptides/semax would remain the canonical Pepticker resource.
