Every statement below reports what a cited source says, with its link. Not medical advice. Adamax: Semax-derived nootropic peptide sold in two variants. The sources cited here most often discuss it for: Focus and clarity, marketing claim; BDNF claim, supplier only; Longer-acting by design, unproven. Evidence label: Unstudied. ## At a glance - **Type:** Peptide - **Family:** Mind & Mood - **Evidence label:** Unstudied (1 of 5) - **Regulatory status:** Not approved by the US FDA or any other regulator, with no registered clinical trials, and it does not appear on FDA's 503A compounding nomination lists. - **Goals discussed:** Focus & Cognition - **Also called:** ADAMAX 1032, Adamax 984, Ac-MEHFPGPAG, Admax - **Last reviewed:** 2026-10-11 ## What is Adamax? - Semax-derived nootropic peptide sold in two variants (source: Wikipedia, Aminos Info, vendor listings). Main ~1032 Da adamantane-conjugated version: C50H69N11O11S, MW ~1032.23, N-acetylated Semax (Ac-MEHFPGPAG) with a C-terminal adamantyl-glycine cap. Alternative ~984 Da unconjugated backbone: C44H61N11O13S, MW ~984.10, Ac-MEHFPGPAG-OH free acid without the adamantyl cap. Not FDA-approved; no published human trials. Sources: Sources: , , , , New Zealand's regulator Medsafe names Adamax as an ACTH analogue related to Semax marketed as a cognitive enhancer, and Wikipedia describes it as Semax carrying the end modifications of the adamantane peptide P021. No peer-reviewed paper, INN or CAS number defines it and products sold under the name conflict (984 Da versus 1032 Da versions, and one education site using the name for a growth hormone secretagogue blend), so its chemical identity is described only by sellers and has not been independently confirmed. **Regulatory status:** Not approved by the US FDA or any other regulator, with no registered clinical trials, and it does not appear on FDA's 503A compounding nomination lists. Source: ## What is Adamax researched for? ### 1. Focus and clarity, marketing claim - Marketed for non-stimulant focus and mental clarity lasting several hours via intranasal use (anecdotal Reddit reports only; claims extrapolated from Semax) Sources: , , - Goals: [Focus & Cognition](https://humanpeptides.fyi/objectives/mind) ### 2. BDNF claim, supplier only - Supplier claims it raises BDNF and hippocampal TrkB sensitivity and improves endurance; no study supports these claims (unsupported vendor claim, per Wikipep review) Sources: , - Goals: [Focus & Cognition](https://humanpeptides.fyi/objectives/mind) ### 3. Longer-acting by design, unproven - Adamantane rationale (more lipophilic, longer-acting, better brain entry) is borrowed from other adamantylated peptides such as P021, not tested for Adamax (theoretical) Sources: - Goals: [Focus & Cognition](https://humanpeptides.fyi/objectives/mind) ## What do researchers and users say about Adamax? > "This class would encompass any analogues of ACTH, such as Adamax and Semax (two peptide products currently marketed as cognitive enhancers)." > > Medsafe (New Zealand Medicines and Medical Devices Safety Authority), Classification of Unscheduled Peptides. Submission to the Medicines Classification Committee (June 2025). Context: Regulator proposal to schedule ACTH analogues intercepted at the New Zealand border as prescription medicines. > "There seems to be limited clinical research on the benefits of ACTH analogues, and little is known about their side effects or long-term effects." > > Medsafe (New Zealand Medicines and Medical Devices Safety Authority), Classification of Unscheduled Peptides. Submission to the Medicines Classification Committee (June 2025). Context: Regulator assessment of the ACTH analogue class that includes Adamax and Semax. > "I felt like I was taking information in a lot more smoothly and effortlessly." > > Anonymous user, r/Biohackers, My Adamax and Selank Experience. Context: Single self-report from a forum user describing the first week of nasal use; the same user reported more headaches and trouble falling asleep. ## What side effects of Adamax are reported? - Headaches, fatigue, nasal irritation and sleep disruption reported, especially at higher/repeated doses (anecdotal Reddit) Sources: - No toxicology or safety data exist Sources: - Unknown interactions with other medicines and unknown product quality; New Zealand's regulator flags this as a health risk for unscheduled imported peptides. (regulator statement) Sources: ## What do peptide guides say about Adamax? - **Medsafe:** Medsafe groups Adamax with ACTH analogues that make nootropic claims such as raising BDNF, notes their mechanism is often unknown, and says unscheduled imported peptides carry unknown quality, efficacy and drug interactions. - **Wikipep:** Searches of Europe PMC and ClinicalTrials.gov found no paper on how Adamax was designed, made, or tested, and no registered trial; no pharmacology, pharmacokinetic or toxicology data exist for it. - **Wikipep:** The only registry record for Adamax, a supplier deposit in PubChem, lists a Semax-based sequence containing no adamantane, which contradicts the same supplier's description of an adamantane-modified compound. - **Seek Peptides:** Seek Peptides describes Adamax as a pre-mixed blend of growth hormone secretagogues whose makeup varies by seller, a description that conflicts with the regulator and encyclopedia accounts of a Semax analogue. - **Aminos Info:** An identity review concludes that products sold as 984 Da and 1032 Da Adamax are different chemical entities, not two grades of one molecule, so the name alone does not define a vial's contents. ## What does the research say, system by system? ### Brain, mood & sleep - Users report 'background' focus, clearer thinking for 3-4 h to all day; some report no effect; some report sleep issues (anecdotal Reddit) Sources: , - Parent compound Semax raised BDNF/TrkB in rat hippocampus (animal, not Adamax) Sources: ### Also notable - Identity/quality concern: products sold as 'Adamax' vs 'ADAMAX 1032' appear to be different compounds by mass spec; only a lot-specific certificate can confirm what a vial contains Sources: ## How strong is the evidence for Adamax? **Unstudied** (1 of 5). Anecdotal only; no animal or human studies; chemical identity unverified (very thin data) _No direct studies of this product or blend. Anecdote and component data only._ ## Questions about Adamax ### What is Adamax? Semax-derived nootropic peptide sold in two variants. New Zealand's regulator Medsafe names Adamax as an ACTH analogue related to Semax marketed as a cognitive enhancer, and Wikipedia describes it as Semax carrying the end modifications of the adamantane peptide P021. No peer-reviewed paper, INN or CAS number defines it and products sold under the name conflict (984 Da versus 1032 Da versions, and one education site using the name for a growth hormone secretagogue blend), so its chemical identity is described only by sellers and has not been independently confirmed. ### Is Adamax FDA-approved? Not approved by the US FDA or any other regulator, with no registered clinical trials, and it does not appear on FDA's 503A compounding nomination lists. ### What is Adamax researched for? The sources cited on this page most often discuss three outcomes: Focus and clarity, marketing claim; BDNF claim, supplier only; Longer-acting by design, unproven. Each line above shows what the source reports and how strong that evidence is. ### What side effects of Adamax are reported? Reported in the cited sources: Headaches, fatigue, nasal irritation and sleep disruption reported, especially at higher/repeated doses; No toxicology or safety data exist; Unknown interactions with other medicines and unknown product quality; New Zealand's regulator flags this as a health risk for unscheduled imported peptides. The list is not complete, and few listed risks does not mean a compound is safe. ### How strong is the evidence for Adamax? Evidence label: Unstudied. Anecdotal only; no animal or human studies; chemical identity unverified (very thin data). ### What else is Adamax called? Names used for it include ADAMAX 1032, Adamax 984, Ac-MEHFPGPAG, Admax. ### Does humanpeptides.fyi recommend Adamax? No. humanpeptides.fyi makes no claims and no recommendations of its own.
