    Adalank

    Nootropic PeptidePreclinical

    Also known as: Adamax-Selank, Adamax + Selank Hybrid, Ada-Lank

    Adalank is a hybrid research peptide combining structural elements of Adamax (the adamantane-modified Semax analog) and Selank (the anxiolytic Pro-Gly-Pro tuftsin analog). Like other Semax/Selank-family hybrids, it's positioned as a single-molecule replacement for users who want both cognitive enhancement and anxiolysis without running two separate peptide protocols. Peer-reviewed literature on Adalank specifically is essentially nonexistent.

    Mechanism of Action

    Mechanism (inferred):

    • Adamax side: BDNF upregulation, D2 receptor modulation, BBB-enhanced delivery via the adamantane group
    • Selank side: GABAergic anxiolysis without sedation, immune modulation, anti-stress profile
    • Combined: "alert calm" similar to NA-Semax + P-21 stacks but with the metabolic stability boost the adamantane modification provides

    Overview

    Adalank is a hybrid research peptide combining structural elements of Adamax (the adamantane-modified Semax analog) and Selank (the anxiolytic Pro-Gly-Pro tuftsin analog). Like other Semax/Selank-family hybrids, it's positioned as a single-molecule replacement for users who want both cognitive enhancement and anxiolysis without running two separate peptide protocols.

    Peer-reviewed literature on Adalank specifically is essentially nonexistent. Pharmacology is inferred entirely from the constituent compounds. Treat it as research-grade and assume Adamax-tier cognitive effects with Selank-tier anxiolytic effects.

    Adamax

    Nootropic PeptidePreclinical / Research compound

    Adamax is a synthetic nonapeptide (Ac-MEHFPGPAG-NH2) classified as a designer analog of Semax.

    t½ ~72 hours receptor binding (community-reported); serum half-life unknown 500-2000 mcg subcutaneous (community research dosing)

    NA-Semax

    Nootropic PeptidePreclinical

    NA-Semax is the N-acetyl-l-aspartyl variant of Semax — the original ACTH(4-7) Pro-Gly-Pro analog developed at the Russian Academy of Sciences in the 1990s.

    NA-Semax Amidate

    Nootropic PeptidePreclinical

    NA-Semax Amidate is the C-terminally amidated NA-Semax — the carboxylic acid at the peptide's C-terminus is replaced with an amide group (-NH2), which is reported to further extend metabolic half-life by resisting carboxypeptidase cleavage in addition to the aminopeptidase resistance the N-acetyl group already provides. The practical effect is a peptide with dosing-frequency leverage: where standard Semax often requires 3-4 daily doses to maintain effect, NA-Semax Amidate is reported (in vendor monographs and community usage) to maintain subjective effects on a 1-2x daily schedule.
