Important dilution note: Cloudiness after dilution is most commonly associated with non-pharmaceutical-grade dilution solution. Cloudy product concerns are not eligible for refund unless Pfizer pharmaceutical-grade dilution solution was used.

Vial Size: 3ml

Grade: 1032 (refers to the ~1032 g/mol molecular-weight form; see Molecular Weight below)

Form: Lyophilized white to off-white powder

CAS Number: None consistently assigned — Adamax has no widely recognized CAS registry number in authoritative chemical databases; it is a proprietary/vendor-designated research peptide rather than a pharmacopeial compound. Some third-party listings display placeholder or unverified CAS values; treat these with caution.

Chemical Name: Adamax — described in vendor literature as an acetylated, C-terminally modified analogue of Semax, applying the N-terminal and C-terminal modifications associated with Peptide 021 (P021). Note: although the "Adam-" name and some listings invoke an adamantane modification, the structure commonly circulated for Adamax (below) is an N-acetylated, C-terminally amidated/extended Semax analogue; whether a literal adamantane group is present is not consistently documented across sources.

Synonyms: N-Acetyl-Semax-Adamantane; Ac-Semax analogue; Adamax peptide

Sequence: Ac-Met-Glu-His-Phe-Pro-Gly-Pro-Ala-Gly-NH₂ (amide) or -OH (free acid), depending on supplier — commonly written Ac-MEHFPGPAG. A 9-residue N-acetylated analogue built on the ACTH(4-7) core (Met-Glu-His-Phe) shared with Semax, extended by Pro-Gly-Pro.

Molecular Formula: C50H69N11O11S (the ~1032 g/mol form most commonly listed for Adamax). The N-acetyl free-acid form (Ac-MEHFPGPAG-OH) is instead reported as C44H61N11O13S (~984 g/mol). Values differ across vendors depending on the C-terminus (amide vs. free acid) and reported modifications — treat as approximate pending your own analytical confirmation.

Molecular Weight: ~1032.2 g/mol (C50H69N11O11S). Free-acid listings report ~984.1 g/mol. No independently established, pharmacopeial value exists.

Purity: ≥98% (HPLC) — see batch COA

Storage Conditions: Store at 2–8°C for short-term (days–weeks) or −20°C for long-term storage, desiccated and protected from light

Solubility: Soluble in DMSO; some vendor documentation reports aqueous solubility for reconstitution (bacteriostatic water), consistent with Semax-class peptides

Receptor Activity: Described in preclinical/research-vendor literature as a Semax analogue investigated for BDNF upregulation and hippocampal TrkB receptor sensitivity; the terminal modifications are proposed to increase resistance to enzymatic degradation and enhance blood-brain-barrier penetration relative to unmodified Semax. Note: unlike Semax (a well-characterized ACTH fragment with published pharmacology), Adamax's mechanism of action is not established in peer-reviewed literature — claims originate from vendor and nootropics-community sources rather than controlled clinical studies.

Regulatory Note: Adamax has been identified as a designer peptide in New Zealand and suggested for prescription-medicine classification there — worth knowing if you're evaluating sourcing or regulatory status.

Certificate of Analysis: Available for all batches (verify with individual supplier).
