Reconstitution chart: 5 mg vial
| BAC water added | Concentration | Draw for 250 mcg dose | Draw for 600 mcg dose |
|---|---|---|---|
| 1 mL | 5,000 mcg/mL | 5 units | 12 units |
| 1.5 mL | 3,333 mcg/mL | 7.5 units | 18 units |
| 2 mL | 2,500 mcg/mL | 10 units | 24 units |
| 2.5 mL | 2,000 mcg/mL | 12.5 units | 30 units |
Draws are U-100 insulin syringe units (100 units = 1 mL). Formula: dose in mcg ÷ (vial mcg ÷ water mL) × 100. The calculator above handles any other combination.
About Semax
Semax is a synthetic peptide developed in Russia from a fragment of adrenocorticotropic hormone, studied there for cognition, focus, and recovery from stroke and other neurological events. Like its sibling Selank, it was used clinically in Russia but carries no FDA or Western approval, and most of the supporting literature is Russian. The Western supply is research-chemical material, and that is how this page treats it.
Semax comes in both a nasal spray and an injectable powder, and you need to know which you have before calculating. The nasal form is common and well represented in the older literature; this page handles the injectable powder only, reconstituted with bacteriostatic water. Spray dosing does not map to syringe units, so confirm your product first. Community protocols for the injectable form typically discuss 250 to 600 mcg per day, sometimes split into two doses because the effect is short-lived.
These are microgram-scale doses, so water is about readability rather than fit. From a 5 mg vial with 1 mL of BAC water, a 250 mcg dose is a 5 unit draw, too small to measure with confidence. At 2.5 mL the same dose becomes 12.5 units, easy to read on an insulin syringe. A 5 mg vial holds 5,000 mcg, covering twenty days at 250 mcg per day. As with every mcg-dosed peptide here, setting the unit toggle to mg produces a 1,000x error, so this page defaults to mcg. Refrigerate the reconstituted vial.
Quick facts
- Status: no Western regulatory approval; most research is Russian
- Two forms circulate: nasal spray and injectable. This page covers the injectable only
- Communities discuss 250 to 600 mcg per day for injection, sometimes split
- Common vial sizes: 5 and 10 mg
Stop gambling on where you buy your peptides.
The calculator tells you how much to draw. The Verified Buyer's Manual tells you how to source the peptide itself without getting scammed or shipped underdosed product. Trace any compound back to the lab that made it, read a Certificate of Analysis and catch a fake, grade any seller before you pay, and price it right. A repeatable system, not a list of names that goes stale.
- How to read a lab report (COA) and spot a faked or misattributed one
- Source tracing: find verified sellers yourself from public test data
- The vetting grid: a yes-or-no scorecard for any seller
- Real cost-per-mg math so you never overpay
- Reconstitution, storage, and the first 72 hours after a package lands
