- Before starting any protocol, researchers must understand the functional differences between Semax formulations. Choosing the wrong form wastes both peptide and study time.
- Semax Acetate
- 70 minutes
- 200–400 mcg
- 2–3× daily
- Acute cognitive demands, short-duration studies
- Rapid onset but requires frequent redosing. Best for time-limited protocols
- Semax Amidate
- 110–130 minutes
- 300–600 mcg
- 1–2× daily
- Sustained neuroprotection, multi-week studies
- Extended stability reduces dosing frequency. Optimal for long-term research
- N-Acetyl Semax Amidate
- 180+ minutes
- 600–900 mcg
- 1× daily
- Maximum duration studies, convenience-focused protocols
- Longest half-life but higher dose required. Use when once-daily dosing is essential
- For researchers new to Semax, the standard amidate form offers the best balance between stability, dosing convenience, and cost-efficiency. The acetate form's 70-minute half-life makes consistent plasma levels difficult to maintain without three-times-daily administration. Practical only in laboratory settings with controlled observation windows.
