SNAP-8 Calculator
SNAP-8 (also known as Acetyl Octapeptide-3) reconstitution and dosage reference — calculate vial concentration, BAC water volume, and exact syringe units below.
At the reference preset of a 5mg SNAP-8 vial reconstituted with 2 mL of bacteriostatic water, a 0.5mg dose measures 20 units on a U-100 insulin syringe.
SNAP-8 is an acetylated octapeptide that extends the Argireline mechanism.

How to use this calculator›
- 1. Vial — the peptide amount printed on the vial, in milligrams.
- 2. BAC water — the bacteriostatic water added to the vial. More water means a lower concentration and a larger, easier-to-read draw.
- 3. Dose — the single dose being measured, in milligrams.
- 4. Syringe — the barrel being drawn into. The diagram rescales to that syringe, so the same dose sits at a different mark on a 0.3 mL barrel than on a U-100.

What is SNAP-8?
SNAP-8 is an acetylated octapeptide that extends the Argireline mechanism. It is a topical cosmetic peptide, not an injectable.

Frequently asked questions
- SNAP-8 vs. Argireline?
- Both target SNARE complex assembly topically. SNAP-8 is two amino acids longer and is marketed as more potent in some formulations.
