Blend Composition
Product Overview
Aventris Labs supplies the NASA Semax + NASA Selank Blend as a pre-mixed, two-component research formulation combining N-Acetyl Semax Amidate and N-Acetyl Selank Amidate in a single lyophilized vial. Each component is sourced from verified manufacturers and independently verified through the Aventris Batch Verification Report (BVR) system.
N-Acetyl Semax Amidate is a synthetic heptapeptide analogue of the ACTH(4-7) fragment with N-terminal acetylation and C-terminal amidation, enhancing metabolic stability (C₃₉H₅₄O₁₀N₁₀S₁, 854.97 Da; sequence: Ac-Met-Glu-His-Phe-Pro-Gly-Pro-NH₂). N-Acetyl Selank Amidate is a synthetic heptapeptide analogue of the immunomodulatory peptide tuftsin, similarly stabilised via acetylation and amidation (C₃₅H₆₀N₁₂O₉, 792.89 Da; sequence: Ac-Thr-Lys-Pro-Arg-Pro-Gly-Pro-NH₂). Both are research-grade peptide reference materials.
By supplying both components pre-mixed in a single vial, Aventris eliminates the need for researchers to source, verify, and combine individual components — streamlining multi-peptide analytical workflows.

Frequently Asked Questions
About the Blend
Is the blend pre-mixed or a multi-vial kit?
Pre-mixed. Both components are combined into a single lyophilized vial — no need to weigh, measure, or combine anything. One vial contains 10mg N-Acetyl Semax Amidate and 10mg N-Acetyl Selank Amidate.
What is the difference between Semax and Selank?
Both are synthetic heptapeptide analogues in N-acetyl amidate form for improved metabolic stability. Semax (Ac-Met-Glu-His-Phe-Pro-Gly-Pro-NH₂) is derived from the ACTH(4-7) fragment. Selank (Ac-Thr-Lys-Pro-Arg-Pro-Gly-Pro-NH₂) is derived from the immunomodulatory peptide tuftsin. They are structurally distinct compounds, independently verified and pre-combined in this blend for multi-component analytical research workflows.
Why does my vial look empty or nearly empty?
This is completely normal. The NASA Semax + NASA Selank Blend contains 20mg of pure peptide with no bulking fillers. A single drop of water weighs approximately 50mg — so 20mg of peptide is less than half a drop. The powder may appear as a thin film on the vial base or a tiny amount of visible material. This is exactly what filler-free, high-purity peptide looks like. Learn more about filler-free peptides →
Quality & Verification
How are the components verified if it’s a blend?
Each component is independently sourced and verified before blending. You receive two individual Batch Verification Reports (BVRs) — one for Semax and one for Selank — each containing the full manufacturer analytical data for that component. Both BVRs are accessible through a single QR code on the vial label.
What is the acetate content note on the Selank BVR?
The Selank batch (Lot P251112-B035) returned an acetate content result of 15.82% against a manufacturer specification of <12.0%. Acetate is a counter-ion, not an active compound — it does not affect peptide purity, identity, or molecular weight, all of which conform to specification. Aventris discloses this result in full and has accepted the batch for distribution following internal QA review. The HPLC purity (99.39%) and peptide content (85.50%) both pass specification.
How do I verify my batch?
Three methods: (1) Scan QR code on product label, (2) Click verification link in order confirmation email, (3) Visit aventrislabs.com/verify/semax-selank-01-2026. All provide instant access to both component Batch Verification Reports.
What analytical data is provided?
Two full BVRs covering — Semax: HPLC purity (99.79%), peptide content (95.64%), ESI-MS (854.97 Da), water content (2.44%), acetate content (5.49%), mass balance (103.57%). Selank: HPLC purity (99.39%), peptide content (85.50%), ESI-MS (792.89 Da), water content (2.34%), acetate content (15.82%, disclosed with QA note), mass balance (103.66%).
