Buy Adamax Peptide Online from SourceTides.
Adamax (N-Acetyl Semax Adamantane; Ac-MEHFPGP-Ad-NH₂) is a synthetic heptapeptide research compound built on the Semax backbone — itself a derivative of ACTH(4-10) — with two pharmacokinetic-enhancing terminal modifications: an N-terminal acetyl group and a C-terminal adamantane (Ad) moiety.
Semax (MEHFPGP) is the well-characterised Russian neuropeptide developed at the Institute of Molecular Genetics of the Russian Academy of Sciences, approved in Russia for cognitive and neuroprotective indications. Adamax extends this backbone by adding N-acetylation (reducing aminopeptidase degradation) and a C-terminal adamantane group — a lipophilic, cage-like bicyclic carbon structure — which increases the peptide’s lipophilicity, enhances blood-brain barrier (BBB) penetration, and extends plasma half-life relative to unmodified Semax.
The proposed research mechanism of Adamax mirrors the well-documented Semax pharmacology: BDNF upregulation, TrkB receptor sensitisation, NGF modulation, and melanocortin system interaction — all extended in duration and potentially amplified in CNS penetration by the adamantane modification.
Important transparency note: Adamax has no published human clinical trials of its own. Its research rationale derives entirely from the Semax parent compound literature. It has been identified by New Zealand Medsafe (June 2025) as a compound requiring prescription medicine classification. All research applications of Adamax should be understood in the context of this limited and highly preliminary evidence base.
Every SourceTides vial is lyophilised, tested at ≥99% HPLC purity, and ships with a full lot-specific Certificate of Analysis.
For in-vitro laboratory research use only. Not for human consumption.

What Is Adamax? Understanding the Semax Lineage

Adamax sits at the intersection of two well-characterised research domains: the Semax neuropeptide family and the pharmacology of adamantane-modified peptides. To understand what Adamax is and what its research rationale is, you need to understand both components.

The Semax Backbone: ACTH(4-10) Neuropeptide Pharmacology

Semax (MEHFPGP) is a synthetic heptapeptide developed at the Institute of Molecular Genetics of the Russian Academy of Sciences and approved in Russia for cognitive and neuroprotective indications. It derives from ACTH(4-10) — a fragment of adrenocorticotropic hormone — extended with a C-terminal Pro-Gly-Pro (PGP) glyproline sequence for metabolic stability. Semax is well-characterised in published research: it upregulates BDNF in the hippocampus (Inozemtsev et al. 2008), modulates serotonin and dopamine systems, activates melanocortin receptors (particularly MC4R), and produces nootropic and anxiolytic effects in multiple animal models. Russian approval data supports its use in cognitive disorders and stroke recovery.

Semax’s primary pharmacokinetic limitation is its short effective duration. Intranasal Semax (the standard clinical route) has BDNF effects measurable within 30 minutes to a few hours — but the peptide is degraded relatively quickly by plasma aminopeptidases and carboxypeptidases. This limits the duration of research experiments and the sustained biological signal available for measurement.

The Two Modifications That Define Adamax

Adamax addresses Semax’s stability limitation through two terminal modifications:

1. N-terminal acetyl group (Ac-): Acetylation of the free amino terminus blocks aminopeptidase attack — the primary route of N-terminal peptide degradation in plasma. This is the same modification used in N-Acetyl Semax Amidate and numerous other stabilised research peptides. N-terminal acetylation typically extends plasma half-life 2–4-fold relative to the unmodified peptide.

2. C-terminal adamantane moiety (-Ad): Adamantane (tricyclo[3.3.1.1³,⁷]decane) is a cage-shaped polycyclic carbon structure known for its exceptional lipophilicity and metabolic stability. Adding it to the C-terminus of a peptide: (a) blocks carboxypeptidase cleavage; (b) dramatically increases the peptide’s logP, improving membrane permeability; (c) enhances blood-brain barrier (BBB) penetration relative to the parent peptide; and (d) provides long-term steric stability. Adamantane is not a novel concept in medicinal chemistry — it appears in FDA-approved drugs including amantadine (antiviral), memantine (Alzheimer’s NMDA antagonist), vildagliptin (DPP-4 inhibitor), and saxagliptin (DPP-4 inhibitor). Its application to peptide C-termini as a BBB-penetration enhancer is an active research strategy supported by multiple published structure-activity studies in the medicinal chemistry literature.

The result of combining both modifications with the Semax backbone is Adamax: a compound designed to deliver the Semax neuropeptide pharmacology to the CNS more efficiently and for longer than the parent compound. When you buy Adamax Peptide 10 mg from SourceTides, you receive the ≥99% purity Ac-MEHFPGP-Ad-NH₂ compound with adamantyl modification confirmed by MS.

The Evidence Hierarchy: What Is Actually Known About Adamax

Critical Research Context: Adamax has no published human clinical trials and no published peer-reviewed animal studies specific to the Adamax compound. Its pharmacological rationale is entirely derived from the Semax parent compound literature. Researchers must understand this evidence gap before designing studies using Adamax. The sections below distinguish clearly between what is known about Semax (well-established) and what is extrapolated to Adamax (hypothesis-based).

Claim	Evidence Level	Source	Applies to Adamax?
Semax increases BDNF in rat hippocampus	In vivo (rat; intranasal; published)	Inozemtsev et al. 2008 — PubMed PMID: 18803097	Extrapolated — the MEHFPGP core sequence is shared; adamantane modification not studied for BDNF specifically
Semax modulates BDNF and TrkB in rat hippocampus	In vivo (rat; published)	Dolotov et al. 2006 — J Neurochem — PubMed PMID: 18474433	Extrapolated — TrkB sensitisation is proposed for Adamax on basis of Semax data
Semax produces nootropic effects (attention, memory, learning)	Russian clinical data; animal behavioural studies	Ashmarin et al. 1997 — foundational Semax review	Extrapolated — Semax nootropic data forms the basis of Adamax efficacy claims; no independent Adamax behavioural data published
Adamantane modification improves peptide BBB penetration	Published medicinal chemistry studies (general; not Adamax-specific)	Medicinal Chemistry Letters — adamantane peptide modification	Directly applicable to Adamax — general adamantane lipophilicity and BBB data applies; Adamax-specific BBB studies not published
N-terminal acetylation extends peptide half-life	Well-established peptide chemistry principle	Multiple peptide chemistry references; standard knowledge	Directly applicable — aminopeptidase resistance from acetylation is compound-independent
Adamax-specific BDNF upregulation	No published peer-reviewed data specific to Adamax	Proposed by analogy with Semax data	Hypothesis only — the adamantane modification could enhance or alter Semax’s BDNF effect in ways not yet studied
Adamax human safety and tolerability	No human studies specific to Adamax	None	Unknown — human safety profile has not been characterised; Semax has excellent safety data but the adamantane modification adds an unstudied element

How Adamax Is Proposed to Work — Mechanisms Inherited from Semax

The proposed mechanisms of Adamax are inherited from its parent compound Semax. The distinction between what is known about Semax and what is extrapolated to Adamax is maintained throughout this section.

BDNF Upregulation and TrkB Sensitisation

Semax upregulates BDNF (Brain-Derived Neurotrophic Factor) in the hippocampus following intranasal administration — confirmed by Inozemtsev et al. (2008; PMID: 18803097) in rats. Dolotov et al. (2006; J Neurochem) confirmed Semax modulates both BDNF mRNA and TrkB receptor expression in the hippocampus. BDNF is the most critical neurotrophic factor for synaptic plasticity, memory consolidation, and stress resilience. Its upregulation by Semax is the best-supported molecular basis for the parent compound’s nootropic and neuroprotective effects.

For Adamax, the same BDNF/TrkB mechanism is proposed by structural analogy — the MEHFPGP sequence is intact, and the adamantane modification is expected to enhance CNS delivery of the active sequence rather than alter its receptor pharmacology. This is a reasonable working hypothesis, but it has not been directly tested with Adamax-specific BDNF assays in published literature. Researchers should include BDNF ELISA alongside behavioural endpoints in any Adamax in-vivo study to generate the Adamax-specific BDNF data that currently does not exist. See the Semax page for context: Semax at SourceTides.

Melanocortin Receptor Interaction (ACTH(4-10) Pharmacophore)

Semax and its ACTH(4-10) origin share the His-Phe-Arg-Trp (HFRW) motif — the same melanocortin receptor-binding core present in α-MSH and ACTH. This motif interacts with melanocortin receptors, particularly MC4R in the brain, driving the cAMP-PKA-CREB cascade that mediates memory consolidation, attention, and stress-axis regulation. The ACTH(4-10)-MC4R axis is well-established in published literature (Catania et al. 2010; Brain Behavior Immunity) as a mechanism for cognitive and neuroprotective effects.

Adamax retains the His-Phe (HF) portion of this pharmacophore within the MEHFPGP backbone. Whether the full melanocortin receptor binding activity of ACTH(4-10) is preserved in Adamax — particularly with the bulky adamantane group at the C-terminus — is not confirmed in published assays for this specific compound. Researchers studying Adamax alongside other melanocortin-active peptides should note the mechanistic overlap with Semax and the mechanistic distinction from Selank Amidate (which is tuftsin-derived and acts on a different system entirely).

NGF and Neurotrophic Support

Semax has been shown to increase NGF (Nerve Growth Factor) levels in preclinical models, particularly in the context of stroke and ischaemic injury. NGF promotes the survival of cholinergic neurons in the basal forebrain — the neurons most important for attention and memory that are selectively lost in Alzheimer’s disease. Adamax is proposed to share this NGF-modulatory property through the conserved Semax core, potentially with improved delivery to target brain regions via the adamantane-enhanced BBB penetration. Again, this is extrapolated from Semax data and has not been directly confirmed for Adamax in published work.

The Adamantane Group’s Pharmacological Contributions

Beyond its role as a pharmacokinetic modifier, the adamantane group itself has documented pharmacological properties in approved drug contexts. Memantine — an adamantane derivative — is an FDA-approved NMDA receptor antagonist used for Alzheimer’s disease. Amantadine — another adamantane compound — has antiviral and dopaminergic properties. These findings raise the question of whether Adamax’s C-terminal adamantane contributes direct pharmacological activity beyond its stability-enhancing role. Specifically, whether the adamantane moiety on Adamax interacts with NMDA receptors, dopamine pathways, or membrane structures directly is an open research question that published literature has not yet addressed for this compound.

Adamax Quality Control at SourceTides

Every batch of Adamax Peptide 10 mg undergoes these tests. The adamantyl modification confirmation is the critical identity checkpoint — distinguishing Adamax from unmodified Semax or N-Acetyl Semax (without the adamantane group).

Test	Method	Specification	Why It Matters
Purity	RP-HPLC (C18; UV 220 nm)	≥99% peak area purity	HPLC separates Adamax from Semax (different MW and elution due to adamantane), N-Acetyl Semax (lacks adamantane; different elution), and synthetic by-products; ≥99% confirms the intended compound dominates
Identity and Adamantyl Confirmation	ESI-MS (expected [M+H]⁺ ~1033 Da; confirms adamantyl mass contribution)	Confirmed MW ~1,032 g/mol; adamantyl group confirmed by mass — absence of adamantane would reduce MW by ~134 Da to Semax range	The adamantane group is the defining structural feature of Adamax vs Semax; MS confirms its presence by the mass increment it contributes; any preparation without this mass is Semax (or N-Acetyl Semax), not Adamax
Endotoxin	LAL chromogenic assay	<1 EU/mg	CNS research is particularly sensitive to endotoxin — LPS activates neuroinflammatory pathways (NF-κB; IL-1β; TNF-α) that directly overlap with the neuroprotective effects being studied; endotoxin confounds all BDNF, neuroplasticity, and cognitive assays
Appearance	Visual inspection	White to off-white powder; no discolouration, no clumping	Clumping indicates moisture absorption (hygroscopic compound); discolouration may indicate Met oxidation in the MEHFPGP sequence
Moisture	Karl Fischer titration	<5% w/w	Low moisture prevents Met sulfoxide formation and preserves mass accuracy for dosing
Certificate of Analysis	Lot-specific PDF	HPLC + MS (adamantyl modification confirmed) + endotoxin + dates	MS confirmation of adamantyl group is the unique identifier for Adamax CoA

Frequently Asked Questions

You can buy Adamax Peptide (N-Acetyl Semax Adamantane; Ac-MEHFPGP-Ad-NH₂) directly from SourceTides. Every order includes a lot-specific Certificate of Analysis with the RP-HPLC chromatogram (≥99% purity), ESI-MS identity confirmation (MW ~1032 Da; adamantyl modification confirmed by mass), and the LAL endotoxin result (<1 EU/mg). All vials are lyophilised and dispatched on dry-ice cold chain. See the SourceTides shipping policy for dispatch details.

Both Adamax and Semax share the same seven-amino acid MEHFPGP backbone derived from ACTH(4-10). The difference is two terminal modifications on Adamax: an N-terminal acetyl group (Ac-) and a C-terminal adamantane moiety (-Ad).

What the modifications do: N-terminal acetylation blocks aminopeptidases from degrading the peptide from the N-terminus — this is the same modification applied in N-Acetyl Semax Amidate and many other stabilised peptides. The C-terminal adamantane group is a cage-shaped lipophilic carbon structure that blocks carboxypeptidase attack, dramatically increases the peptide’s lipophilicity and membrane permeability, and is proposed to enhance blood-brain barrier penetration.

What this means for research: Adamax is designed to deliver the Semax pharmacology (BDNF upregulation, TrkB sensitisation, nootropic effects) with greater CNS penetration and longer duration. The practical trade-off is that Semax has a well-established published evidence base (Russian regulatory approval; multiple published studies), while Adamax has no published peer-reviewed studies specific to the compound. Semax should always be included as the comparator when studying Adamax, to attribute any observed differences to the adamantane modification specifically.

The honest answer: the evidence base for Adamax specifically is very limited. No peer-reviewed human clinical trials or published animal studies exist for the Adamax compound as such. Its research rationale derives entirely from:

1. The well-established Semax parent compound literature (strong evidence — Russian approval; multiple PMC publications on BDNF, TrkB, cognitive effects, neuroprotection).

2. General principles of N-terminal acetylation (well-established peptide chemistry — aminopeptidase resistance).

3. Published medicinal chemistry studies on adamantane-modified compounds (general; not Semax-specific).

This evidence hierarchy means Adamax is a reasonable research hypothesis based on established parent compound pharmacology and sound modification chemistry — but it has not been independently validated as a compound. Researchers should design Adamax studies with this in mind: include Semax as the positive control, include vehicle control, and generate BDNF/TrkB molecular readouts alongside any behavioural endpoints. The first published Adamax studies will be the ones your protocol generates. For more established neuropeptide evidence, Semax and Selank Amidate have published PMC data supporting their mechanisms.

New Zealand’s Medicines Classification Committee (Medsafe) reviewed a category of unscheduled ACTH-analog peptides in June 2025, including Adamax and Semax, and determined they should be classified as prescription medicines. The designation “designer drug” in Wikipedia refers to the fact that Adamax was identified in border seizures in New Zealand as a compound being sold as a cognitive enhancer without pharmaceutical oversight. The “designer drug” classification in this context means an engineered compound distributed outside conventional pharmaceutical channels — not that it is a scheduled controlled substance in the sense of illicit drugs.

The NZ Medsafe action was a proactive regulatory measure in response to increasing availability of ACTH-analog peptides marketed for cognitive enhancement online. The prescription classification means that in New Zealand, Adamax is now regulated as requiring a prescription for clinical use. This does not affect laboratory research use within institutional settings with appropriate ethical oversight. Researchers outside New Zealand should verify the regulatory status in their own jurisdiction. SourceTides supplies Adamax for in-vitro laboratory research use only.

In the USA, Adamax is not a DEA controlled substance and is available as a research compound for laboratory use. In the UK, it is not controlled under the Misuse of Drugs Act 1971. In Canada, it is not a CDSA controlled substance. In Australia, verify current TGA scheduling — the NZ Medsafe action may trigger parallel TGA review. In New Zealand specifically, Adamax was classified as a prescription medicine by Medsafe in June 2025. Researchers in New Zealand should obtain appropriate authorisation before ordering. WADA status: Semax (parent) is not prohibited; Adamax’s WADA status has not been explicitly reviewed but is likely similar — verify at wada-ama.org. SourceTides supplies for in-vitro laboratory research only. See the SourceTides shipping policy for jurisdiction details.

Adamax is less water-soluble than Semax due to the lipophilic adamantane group. Recommended reconstitution approach: (1) Dissolve in DMSO to a concentrated stock (5–10 mg/mL); (2) Dilute into sterile PBS or cell culture media to your working concentration, ensuring final DMSO does not exceed 0.1% in the assay (higher DMSO concentrations affect cell viability). Alternatively, for aqueous protocols: try 30% ethanol in PBS (v/v) as a vehicle, then dilute to ≤5% ethanol working concentration. Swirl gently — do not vortex. Filter through 0.22 µm syringe filter before cell culture use. For BDNF ELISA assays in primary hippocampal neurons or SH-SY5Y cells: working concentration range 0.1–10 µM based on Semax literature; run full dose-response for Adamax-specific characterisation.
