- Thymosin Alpha-1
- Oxidation, heat-induced unfolding, aggregation
- Cloudiness, yellow discoloration, particles
- High. Potency loss occurs without visible change above 8°C
- 12–24 months
- 28 days
- BPC-157
- Oxidation of cysteine residues, pH-dependent aggregation
- Cloudiness, clumping, color shift to amber
- Moderate. Visual signs correlate with potency loss
- 18–24 months

- GHK-Cu
- Copper ion dissociation, oxidation
- Blue-green discoloration, precipitation
- Low. Color change is immediate and obvious
- 24 months
- Cerebrolysin
- Proteolytic degradation, thermal denaturation
- Cloudiness, particles
- High. Liquid formulation degrades faster than lyophilised
- N/A (liquid formulation)
- 60 days (unopened vial)
