About Semax

A 7-amino-acid synthetic peptide derived from the ACTH(4-10) sequence, studied for cognitive enhancement, neuroprotection, and focus.

Research dose ranges

  • Dose: 200600 mcg per administration
  • Frequency: 2× per day
  • Route: nasal
  • Half-life: ~0.1 hours
  • Cycle: 4 weeks on / 2 off

Semax is most commonly administered intranasally (1–2 drops per nostril of a 0.1% or 1% solution). Research protocols typically use 200–600 mcg per dose, one to two times daily. Injectable formulations also exist but are less common in research settings outside clinical trials.

Storage

Semax solution should be refrigerated at 2–8°C and protected from light. Lyophilized powder is stable at room temperature short-term; reconstituted solution should be used within 30 days when refrigerated.

Semax calculator FAQ

How do I use the Semax calculator?+

Confirm your vial size in mg (default 0.5), set the diluent volume in mL (default 1), enter your target dose, and the calculator returns the concentration, the exact insulin-syringe units to draw, and how many doses your vial yields.

What's the standard Semax reconstitution?+

Most Semax research protocols reconstitute a 0.5 mg vial with 1 mL of bacteriostatic water, yielding 500 mcg/mL.

What syringe should I use for Semax?+

U-100 insulin syringes are standard for Semax nasal administration. 0.5 mL barrels have clearer unit markings for typical research doses.

Does the Semax calculator support mg and IU?+

Yes. Enter your dose in mcg, mg, or IU. For IU, set the mcg-per-IU ratio (333 for HGH is a common default).
