# Adamax > Adamax is a research peptide described as an adamantane-modified analog of Semax, the synthetic heptapeptide Met-Glu-His-Phe-Pro-Gly-Pro derived from ACTH(4-7). Its exact structure is not documented in PubChem, and no peer-reviewed studies of Adamax were found in PubMed as of October 2026. It is not approved by the FDA for any use. Canonical: https://peptideproperties.com/compounds/adamax/ ## Identity - **Class:** Neuropeptides & Nootropic Research Compounds - **Also known as:** Adamantane-modified Semax analog - **Sequence notes:** Described as Semax (Met-Glu-His-Phe-Pro-Gly-Pro) bearing an adamantane-derived group; attachment site and full structure not documented in PubChem or peer-reviewed literature ## Key facts - Class: described as an adamantane-modified analog of the heptapeptide Semax - Parent peptide: Semax, Met-Glu-His-Phe-Pro-Gly-Pro - Adamantane attachment site and full structure not publicly documented - No PubChem record; no verified formula or molecular weight - No peer-reviewed studies found in PubMed as of October 2026 - Not approved by the US FDA for any use ## What Is Adamax? Adamax is a research peptide described as an adamantane-modified analog of Semax, the synthetic heptapeptide Met-Glu-His-Phe-Pro-Gly-Pro. Semax itself combines the ACTH(4-7) fragment of adrenocorticotropic hormone with a C-terminal Pro-Gly-Pro tripeptide; Adamax adds an adamantane-derived group to that peptide.No peer-reviewed studies of Adamax were found in PubMed as of October 2026. The compound also has no PubChem record, so its exact structure, including where the adamantane group is attached and whether the termini are otherwise modified, is not documented in an authoritative public database.Because adding a bulky group can change how a peptide binds, is degraded and distributes in biological systems, published findings on Semax should not be assumed to apply to Adamax. This page therefore limits itself to what can be stated about the compound's identity. ## Chemical Structure and Molecular Identity Adamax is described as Semax carrying an adamantane-derived modification, but no verified structure, formula or molecular weight is available. Without a PubChem entry or a peer-reviewed characterization, this page does not state a formula, molecular weight, CAS number or InChIKey.Adamantane is a rigid, cage-shaped hydrocarbon with the formula C10H16. Attached to a peptide, an adamantyl or adamantoyl group adds a compact, strongly hydrophobic unit to an otherwise polar molecule. For comparison, PubChem lists the unmodified parent, Semax, with the formula C37H51N9O10S and a computed XLogP of -2.8. ### Identity at a glance - Parent peptide: Semax (Met-Glu-His-Phe-Pro-Gly-Pro), PubChem CID 9811102 - Reported modification: adamantane-derived group; attachment site not documented - PubChem record: none found - Sequence of the modified molecule: not verifiedBecause the name alone does not specify the attachment chemistry, two materials labeled with the same name could in principle differ in structure. Mass spectrometry and, ideally, structural data are needed to establish what a given sample contains. ## What the Published Literature Covers No published study in PubMed has examined Adamax. A search for the name returned only unrelated computer-science work in which "Adamax" refers to an optimization algorithm used to train machine-learning models, not to a peptide.There are therefore no peer-reviewed data on the compound's structure confirmation, stability, receptor interactions, behavior in cell or animal models, or effects in humans. The parent peptide Semax has its own body of cell and rodent research, summarized on the Semax reference page, but none of it was performed with Adamax.Because Adamax has no public structure record, mass spectrometry and HPLC data on a certificate of analysis are essential for confirming what a sample contains. ## Regulatory and Research Status Adamax is not approved by the US Food and Drug Administration for any use, and no clinical trials of it were found. It is handled only as a research compound, and peer-reviewed data on it are absent from PubMed as of October 2026.With no public structure record, Adamax is less well defined than most research peptides. Laboratories working with it depend on independent analytical data, such as mass spectrometry and HPLC, to confirm molecular mass, purity and the presence of the adamantane modification. ## FAQ **Is Adamax the same as Semax?** No. Adamax is described as an analog of Semax that carries an adamantane-derived group, whereas Semax is the unmodified heptapeptide Met-Glu-His-Phe-Pro-Gly-Pro. The exact structure of Adamax is not documented in PubChem or peer-reviewed literature, and research on Semax has not been shown to apply to it. **Is Adamax FDA approved?** No. Adamax is not approved by the US Food and Drug Administration for any use, and no clinical trials were found. It is handled only as a research compound, and no peer-reviewed studies of it appeared in PubMed as of October 2026. **What does the research on Adamax show?** There is no peer-reviewed research on Adamax in PubMed as of October 2026. Searches for the name return papers about an unrelated machine-learning optimization algorithm also called Adamax. Studies of the parent peptide Semax exist, but they were not performed with the adamantane-modified analog and cannot be assumed to apply. **What is the molecular weight of Adamax?** No verified molecular weight is available. Adamax has no PubChem record, and its exact structure, including where the adamantane group is attached, is not documented in peer-reviewed literature. For comparison, PubChem lists the parent peptide Semax at 813.9 g/mol; the mass of a specific sample must be confirmed by mass spectrometry.
