- 15–25%
- High stability. 18-month shelf life at −20°C
- Synthesis date verification sufficient
- Ideal for February promotions. Long stability window allows bulk purchasing with minimal degradation risk
- Cognitive Enhancement Peptides (Dihexa, Cerebrolysin, P21)
- 20–30%
- Moderate. Oxidation-prone sequences require strict cold chain
