How many units of Semax should I draw?

It depends on your vial size, BAC water, and dose. For a 5mg vial with 2mL BAC water, a beginner dose of 200mcg is typically 8 units on a U-100 syringe. Use the calculator above for your exact numbers.

How much BAC water should I add to Semax?

The standard amount is 2mL of bacteriostatic water for a 5mg vial. More water gives a more dilute solution — easier to measure small doses. Less water means fewer injections per vial. Adjust the BAC water slider in the calculator to see how it changes your syringe units.

How long does a Semax vial last?

At a beginner dose of 200mcg daily, a 5mg vial lasts about 25 doses. The calculator shows exact doses per vial for your selected tier.

What syringe should I use for Semax?

Most people use a U-100 insulin syringe (1mL / 100 units). For very small doses, a U-50 or U-30 syringe gives better precision. The calculator adjusts units automatically for whichever syringe you pick.

Disclaimer: This curve is a simplified first-order exponential decay model. Actual pharmacokinetics vary based on injection site, individual metabolism, body composition, and other factors. Half-life values are approximate and based on available preclinical and clinical literature. Many research peptides lack formal human pharmacokinetic studies.

About Semax

Semax is a synthetic peptide analog of ACTH (adrenocorticotropic hormone) developed in Russia for stroke treatment and cognitive enhancement. It powerfully increases BDNF (brain-derived neurotrophic factor) — the key protein for learning, memory, and neuroplasticity. Unlike ACTH, Semax does not affect cortisol or the adrenal glands. It's approved in Russia for stroke, cognitive disorders, and peptic ulcers.
