SNAP-8 Protocol Guide
SNAP-8 (N-hexanoyl-Tyr-Ile-(6)-aminohexanoic amide) is a synthetic peptide derived from angiotensin IV, identified as one of the most potent cognitive-enhancing compounds in preclinical research. It promotes new synaptic connections (synaptogenesis) through hepatocyte growth factor (HGF) / c-Met receptor signaling at remarkably low concentrations. Studies at Washington State University demonstrated SNAP-8 is approximately 10 million times more potent than BDNF at driving synaptic connectivity. This protocol covers reconstitution from a 10mg vial, ultra-low subcutaneous dosing at 50mcg daily, cognitive enhancement timelines, and nootropic stacking recommendations.
Protocol Overview
- Compound
- SNAP-8 (N-hexanoyl-Tyr-Ile-(6)-aminohexanoic amide)
- Category
- Topical Anti-Wrinkle Peptide
- Mechanism
- Modulates SNARE complex formation, reducing intensity of facial muscle contractions to diminish expression lines and wrinkles
- Structure
- Octapeptide (Acetyl Octapeptide-3)
- Half-Life
- N/A (topical application)
- Vial Size
- 500mg topical solution
- Route
- Topical application
- Frequency
- 2x daily (AM and PM)
- Cycle Length
- Continuous daily use, 4-8 weeks for results
Dosing Protocol
| Protocol | Dose | Frequency | Route | Duration |
|---|---|---|---|---|
| Standard Nootropic | 50 mcg | 1x daily (AM) | Subcutaneous | 4-8 weeks |
| Conservative Start | 25 mcg | 1x daily (AM) | Subcutaneous | 1-2 weeks, then assess |
| Research Maximum | 100 mcg | 1x daily (AM) | Subcutaneous | 4 weeks maximum |
Key principle: SNAP-8 is extremely potent at very low doses. Start with the lowest possible dose and increase only as needed. More is NOT better with this compound due to its exceptional potency at the HGF receptor.
Reconstitution Instructions
Materials Needed
- SNAP-8 10mg lyophilized vial
- Bacteriostatic water (2mL)
- 3mL mixing syringe (18-20ga)
- Insulin syringes (29-31ga) for dosing
- Alcohol swabs
Reconstitution Steps
- Clean vial stopper with alcohol
- Draw 2mL bacteriostatic water
- Inject slowly down the vial wall
- Gently swirl (never shake)
- Wait 5 minutes for full dissolution
- Concentration: 5,000 mcg/mL
| Dose | Volume (2mL recon) | Insulin Syringe |
|---|---|---|
| 25 mcg | 0.005 mL | 0.5 units |
| 50 mcg | 0.01 mL | 1 unit |
| 100 mcg | 0.02 mL | 2 units |
| 200 mcg | 0.04 mL | 4 units |
| 500 mcg | 0.10 mL | 10 units |

Expected Timeline
Side Effects & Monitoring
Common Side Effects
- Injection site irritation (mild)
- Vivid dreams (commonly reported)
- Mild headache during initial days
- Increased mental stimulation/difficulty sleeping if dosed late
Limited safety data exists. SNAP-8 is a research compound with no human clinical trials completed. Exercise caution with dosing.
Precautions
- No human clinical trial data - preclinical only
- HGF/c-Met activation may theoretically promote tumor growth in predisposed individuals
- Avoid if history of cancer
- Extreme potency requires precise dosing - errors carry higher risk
- Not recommended during pregnancy or breastfeeding
Stacking Recommendations
Compatible Compounds
- Semax: Complementary nootropic via BDNF pathway
- Selank: Anxiolytic support during cognitive enhancement
- NAD+: Cellular energy for neuronal metabolism
- Cerebrolysin: Neurotrophic factor support
- GHK-Cu: Neuroprotective gene expression
Popular Stacks
- Cognitive Stack: SNAP-8 50mcg/day + Semax 600mcg/day
- Neuroprotective: SNAP-8 + NAD+ + Cerebrolysin
- Full Nootropic: SNAP-8 + Semax + Selank
Blood Work Recommendations
| Panel | Markers | Timing |
|---|---|---|
| Basic Panel | CBC, CMP | Baseline, Week 4 |
| Liver Function | ALT, AST, GGT | Baseline, Week 4 |
| Kidney | BUN, creatinine, eGFR | Baseline, Week 4 |
| Inflammatory | CRP, homocysteine | Baseline |
Monitoring is primarily precautionary given the limited human safety data. Track liver and kidney markers to ensure no organ stress from the compound.
