# Adamax

Vendor-invented adamantyl Semax variant; stronger, longer focus per users.

- Page: https://peprank.xyz/peptides/adamax
- Category: Focus & memory (Research peptide)
- Also known as: Adamantane-modified Semax; 'Semax-1032'/'984' (vendor labels)
- Routes: Nasal / Injection
- Sequence: MEHFPGP (Semax analogue: N-terminal adamantane-derived acyl group, C-amide (exact chemistry vendor-described, not peer-reviewed))
- Safety tier: Strict: Caution · Balanced: Caution · Evidence only: Clean
- Risk axes (0 none to 3 severe): Seen harm 0, Mechanism 1, Data gap 3, Silent harm 1, Product 3
- Positive: 48% of 29 graded reports glowing or positive, shrunk toward the 49% all-report average by 8 reports' weight
- Rank: #16 of 61 research peptides
- Graded reports: 29 (Glowing 2, Positive 12, Mixed 4, Nothing 7, Negative 3, Bad reaction 1)
- Evidence: No studies of its own — Vendor claims only
- Access: Grey market
- Onset: Subq within an hour or two, nasal faster; a few users only noticed it after 4-5 days of daily dosing.
- Lasts: Most of the working day (users report 4-8 hours, longer than Semax); doses after noon disturb sleep, and some describe a crash or a 2-3 day comedown.
- Cost per month: ≈ €23–92 (at 150–600 mcg/day, Semax Polska at €5.12/mg)
- Updated: 2026-10-30

**Why Avoid under the strict bar:** A novel molecule with no published animal or human safety data, sold only by grey-market vendors.

## What users report

Users often find it stronger and longer than Semax: all-day non-jittery focus, sharper vision, emotional 'thaw' after blunting. Others get fatigue, late-day headache, or nothing; vendor labels (984 vs 1032) are confused. Roughly 30-40% feel little.

**Effects:** long non-jittery focus; emotional reactivity returns (anti-blunting); visual sharpness; task initiation

**Downsides:** fatigue/lethargy (some); headache; insomnia if dosed after noon

**Risks:** no published preclinical or clinical data of any kind; structure, purity and pharmacology unverified; novel chemical modification (adamantane) whose effects are unknown

**Typical use:** 150-600 mcg/day nasal or subq, mornings (community).

**Getting it:** Grey-market only, created by the defunct vendor Ceretropic; often out of stock. Vendors sell two different molecules under the name (about 984 Da and 1032 Da) and none of it is independently characterised.

**Stacked with:** Selank or Adalank (Adamax in the morning for focus, Selank or Adalank in the evening to wind down; several users run this pairing.); Stimulants (Vyvanse, Adderall, modafinil) (Users say it synergises with them; coffee a few hours after a dose made one user jittery, and some take it only on stimulant-free days.); Bromantane and Dihexa (Stacked by one NooTopics user on days off Vyvanse.)

## Risk profile

- **Seen harm 0/3:** No study exists; about thirty first-hand reports describe fatigue, headache and one severe migraine, none serious. The zero reflects community use only.
- **Mechanism 1/3:** Said to be Semax with an adamantane group added, but no structure, pharmacology or animal paper exists; any harm path is speculative.
- **Data gap 3/3:** Verified null: no published preclinical or clinical data at all, and vendors sell two different molecules (about 984 and 1032 Da) under the name.
- **Silent harm 1/3:** Reported effects (fatigue, headache, insomnia) are felt within hours.
- **Product 3/3:** Grey-market only, more often injected than sprayed, of uncharacterised identity.
- **Never if:** Pregnancy or breastfeeding (no human reproductive data)

## Top reports

- Glowing, focus, 300-400 mcg/day, 5 days a week, not after 2 PM: “I love Adamax subQ. Amazing for hours of non jittery focus and clarity. Works way better for me than Semax and Selank/Semax subQ. Never tried any of them in nasal form.” — [r/NTNPerformance](https://www.reddit.com/r/NTNPerformance/comments/1wr389m/adamax_experience/pchf2k2/)
- Glowing, focus: “Adamax keep it to morning and noon, don’t use past noon as it does prevent rest I’ve noticed if used 6-8 hrs before. The focus is immense, tasks are completed throughly and with more thought.” — [r/NTNPerformance](https://www.reddit.com/r/NTNPerformance/comments/1wr389m/adamax_experience/pcd5gl8/)
- Positive, focus, 3 or 4 sprays each side: “This spray gives me a smaller version of that. I stay in the chair. Spreadsheets get done. The proposal deck gets built.” — [@lakemandude on X](https://x.com/lakemandude/status/2113383369346293777)
- Positive, focus, 500 mcg/day: “Around a week in I started noticing pretty big improvements in memory, the stuff I was studying was sticking alot better. However I also noticed a few minor side effects, headaches were happening a lot more frequently and I found It was harder to fall asleep.” — [r/Biohackers](https://www.reddit.com/r/Biohackers/comments/1tabio8/my_adamax_and_selank_experience/)
- Positive, mood, 500 mcg/day: “I feel like I’m actually appreciating things again. Music hits harder, small things make me happier, and I feel more present in general.” — [r/NooTopics](https://www.reddit.com/r/NooTopics/comments/1w9msoz/adamax_i_think_im_finally_starting_to_feel_things/)

## Studies

- [Parent molecule Semax (no Adamax study exists): Dolotov et al. 2006, Semax regulates BDNF and trkB expression in the rat hippocampus](https://pubmed.ncbi.nlm.nih.gov/16996037/) (animal, 2006): The BDNF mechanism vendors claim for Adamax comes from Semax work like this, where one intranasal dose raised hippocampal BDNF 1.4-fold in rats; it has never been tested for Adamax.
- [Parent molecule Semax (no Adamax study exists): Gusev et al. 2018, efficacy of Semax at different stages of ischaemic stroke](https://pubmed.ncbi.nlm.nih.gov/29798983/) (controlled, n=110, 2018): Semax added to rehabilitation raised plasma BDNF and improved motor recovery after stroke; no comparable data exist for the adamantane-modified version.
