SNAP-8: dosing, reconstitution and evidence

An eight-amino-acid topical peptide that interferes with SNARE complex formation to soften expression lines — sometimes marketed as a topical alternative to botulinum toxin.

Also known as Acetyl Octapeptide-3

What to expect

Most people tolerate SNAP-8 well. Here is what is worth knowing going in, so nothing catches you by surprise.

Well tolerated, with a clean safety record. It is topical — it belongs on skin, not in a syringe. Expect something subtle: the botulinum comparison oversells it, and getting through intact skin is the real limitation, so delivery vehicle matters as much as the peptide.

Reconstitution guide

SNAP-8 ships as a lyophilised powder and gets mixed with bacteriostatic water before use. How much water you add sets the concentration, which sets how many syringe units make up each dose. One unit on a U-100 syringe is 0.01 mL — the tables below do the arithmetic for the vial sizes you are most likely to be holding.

SNAP-8 is a blend, so the ratio differs between suppliers. The concentrations below are for total peptide — check your vial label for the split, then dose off that.

5mg vial most common

Water addedConcentration
1mL (common) 5 mg/mL
2mL 2.5 mg/mL

Standard steps

  1. Inspect the vialConfirm the label and that the powder cake is intact. Do not use a cracked or compromised vial.
  2. Let it reach room temperatureSitting out for a few minutes reduces condensation inside the vial when the seal is broken.
  3. Disinfect both stoppersWipe the compound vial and the bacteriostatic water vial with a fresh alcohol swab and let them air-dry.
  4. Draw the bacteriostatic waterUse a sterile syringe to draw the volume you have chosen from the reconstitution table.
  5. Add the water down the vial wallInject slowly so it runs down the inside wall rather than spraying directly onto the powder. This limits foaming.
  6. Dissolve gentlySwirl or roll the vial between your hands until the cake dissolves. Never shake — agitation damages peptide bonds. The solution should end up clear.
  7. Label and refrigerateWrite the reconstitution date and concentration on the vial. Store at 2–8°C. Do not freeze.
