SNAP-8 (10 mg Vial) Dosage Protocol
SNAP-8 (acetyl octapeptide-3) is a topical cosmetic peptide modeled on part of SNAP-25, studied for expression-line reduction. This is a TOPICAL research peptide — used in creams, serums, or dissolving microneedle patches at 0.0015%–0.005% active concentration. Not intended for injection.

Active-peptide concentration math for a SNAP-8 10 mg vial
Whole 10 mg Vial Concentration Calculator
These rows show the mathematical concentration produced when the complete 10 mg vial is distributed through a measured final batch weight. Smaller batches produce higher concentrations; none establishes a validated use level.
| Final Batch | Active Peptide | Active % w/w | ppm | Research Context |
|---|---|---|---|---|
| 30 g | 10 mg | 0.0333% w/w | 333 ppm | Calculation example |
| 50 g | 10 mg | 0.0200% w/w | 200 ppm | Calculation example |
| 100 g | 10 mg | 0.0100% w/w | 100 ppm | Calculation example |
| 333.3 g | 10 mg | 0.0030% w/w | 30 ppm | Mid-range calculation |
Formula: Active percent w/w = peptide mg divided by final batch grams divided by 10. Parts per million = peptide mg divided by final batch grams multiplied by 1,000.
Small-Batch SNAP-8 Research Calculations
A typical 30 g or 50 g topical batch requires a measured portion of the vial to match the 0.0015% to 0.005% active reference range.
| Final Batch | 0.0015% Active | 0.0030% Active | 0.0050% Active |
|---|---|---|---|
| 30 g | 0.45 mg | 0.90 mg | 1.50 mg |
| 50 g | 0.75 mg | 1.50 mg | 2.50 mg |
| 100 g | 1.50 mg | 3.00 mg | 5.00 mg |
Formula: Peptide mg needed = target percent multiplied by final batch grams multiplied by 10.
Worked 1 mg/mL Stock Measurement Example
If a validated formulation plan uses the complete 10 mg vial in a measured 10.0 mL final stock volume, the nominal stock concentration is 1 mg/mL. Each 1.0 mL contains 1.0 mg SNAP-8. The stock must use a compatible vehicle, and the transferred amount becomes part of the final batch.
| Final Batch | Stock for 0.0015% | Stock for 0.0030% | Stock for 0.0050% |
|---|---|---|---|
| 30 g | 0.45 mL | 0.90 mL | 1.50 mL |
| 50 g | 0.75 mL | 1.50 mL | 2.50 mL |
| 100 g | 1.50 mL | 3.00 mL | 5.00 mL |
Important: This is measurement math, not a shelf-life claim. A base must accept the added aqueous phase without losing homogeneity or preservation. The analytical-standard result does not validate the stability of a finished topical stock or cream.
Concentration math does not validate homogeneity, preservation, pH, compatibility, skin delivery, or shelf life. Those controls belong to the finished formulation.
Supplies Needed
Use a complete, measured formulation set for each SNAP-8 topical research batch.
| Item | Quantity |
|---|---|
| SNAP-8 10 mg research vial | Record lot number, identity, assay, purity, and certificate of analysis. |
| Validated cosmetic research base | A compatible cream, gel, or serum base with a documented formula and preservation system. |
| Compatible stock vehicle | Use only when a validated formulation plan requires a measured stock. |
| Calibrated analytical balance | Needed for final batch weight and direct mass measurements within its validated range. |
| Calibrated pipettes or positive-displacement tools | Needed when an accurately quantified liquid stock is used. |
| Clean mixing and transfer tools | A suitable vessel, spatula, transfer tools, and validated homogenization method. |
| pH measurement | A calibrated meter or validated narrow-range strips. |
| Clean handling supplies | Clean gloves, alcohol preparation materials, and a disinfected work surface. |
| Final container | A compatible opaque or airless container with a secure closure and measurable dispenser. |
| Label and batch log | Record active mass, final weight, concentration, vehicle, pH, container, date, storage, and observations. |
| Stability observation log | Track appearance, odor, separation, pH drift, container compatibility, and validated testing. |
Storage Instructions
| State | Temperature | Duration |
|---|---|---|
| Lyophilized | −20°C (−4°F) | Up to 24 months, dry & dark |
| Reconstituted | 2–8°C (35–46°F) | Up to 0 days, protect from light |
Important Notes
How This Works
SNAP-8 is acetyl octapeptide-3, an eight-amino-acid peptide modeled on part of SNAP-25 (sequence Ac-EEMQRRAD-NH2). The proposed cosmetic mechanism is interference with SNARE-complex assembly and calcium-dependent exocytosis, which may reduce muscle contraction responsible for expression lines. Direct mechanism data are primarily developer-generated. Distinct from Argireline (acetyl hexapeptide-8).
Potential Benefits & Side Effects
Potential Benefits
- ~35% mean and 63% max wrinkle-depth reduction (manufacturer 28-day panel, 0.005% cream twice daily).
- Improvements in fine lines and hydration when combined with other actives in microneedle patches or serums.
Side Effect Profile
- Generally well-tolerated topically.
- Independent SNAP-8 effect isolated only in the manufacturer panel — most published studies combine with other peptides.
Lifestyle Factors
- Consistent daily application for 28+ days for measurable effect.
- Photograph target area with consistent lighting for research documentation.
Injection Technique
- ⚠ TOPICAL ONLY. Do not inject.
- Formulate into a preserved cream, gel, or serum base at 0.0015%–0.005% active concentration.
- Apply twice daily around target area.
