How Adamax Works

Adamax is the most potent modification of Semax, featuring both N-acetylation and C-terminal amidation for enhanced stability, bioavailability, and blood-brain barrier penetration. Like Semax, it is derived from ACTH(4-10) but with modifications that enhance neurotrophic activity. It increases BDNF (brain-derived neurotrophic factor) and NGF (nerve growth factor) expression, modulates serotonergic and dopaminergic systems, enhances cerebral blood flow, and provides neuroprotection through anti-oxidant and anti-inflammatory mechanisms. The added modifications extend duration and increase potency over standard Semax.

Research Applications

Reconstitution Calculator

Add this much bacteriostatic water:
5.0 mL
5 mg Adamax + 5.0 mL BAC water = 1 mg/mL

Inject bacteriostatic water slowly along the vial wall. Gently swirl until dissolved — never shake. Store reconstituted solution at 2-8°C and use within 30 days.

Frequently Asked Questions

Adamax (CAS: 2920938-90-3) is a research compound, with a molecular weight of 855.97 Da in the Cognitive / Neuropeptides category. Adamax is the most potent modification of Semax, featuring both N-acetylation and C-terminal amidation for enhanced stability, bioavailability, and blood-brain barrier penetration. Like Semax, it is derived from ACTH(4-10) but with modifications that enhance neurotrophic activity. Researchers commonly investigate Adamax for Enhanced cognitive performance and memory, Neurotrophin upregulation (BDNF, NGF), Neuroprotection from oxidative damage. Every vial from MiPeptidos includes batch-specific analytical documentation.
Adamax is available in 2 sizes (5mg, 10mg), so reconstitution volume depends on which vial you have. For the 5mg size, add 1-2mL of bacteriostatic water; for the 10mg size, use 2-3mL. Always let the vial warm to room temperature first, inject the water slowly along the vial wall, and swirl gently — never shake. Store reconstituted Adamax at 2-8°C and use within 30 days. MiPeptidos carries bacteriostatic water in 3mL and 10mL vials.
Adamax (Adamantane-modified ACTH fragment, 856 Da) and Semax (813 Da) are both nootropic peptides derived from the ACTH/MSH axis, but Adamax has an adamantane group that enhances lipophilicity and blood-brain barrier penetration. Both target melanocortin receptors and BDNF/NGF expression, but Adamax bulkier hydrophobic modification may improve CNS residence time. Semax has more published clinical data from Russian neurology research. MiPeptidos stocks both for cognitive enhancement studies.
Store lyophilized Adamax at -20°C for maximum long-term stability — properly stored, it remains potent for 24+ months. Once reconstituted with bacteriostatic water, keep it refrigerated at 2-8°C and use within 30 days. In research applications, Adamax has a reported half-life of Extended over Semax (~several hours) due to modifications, which informs dosing frequency and protocol design. Avoid repeated freeze-thaw cycles and protect from direct light. MiPeptidos ships every order with cold-chain packaging to maintain integrity during transit.
Every Adamax order from MiPeptidos includes a batch-specific Certificate of Analysis. Our current batch (HR-DMX-2600115, tested March 23, 2026) shows 99.3% purity by HPLC, mass spectrometry confirmation at 855.97 Da, endotoxin levels below 0.1 EU/mg, and passing sterility per USP <71>. This level of documentation ensures you can verify compound identity and purity before beginning your research. MiPeptidos also offers bulk pricing on orders of 50+ vials — contact info@mipeptidos.com.
