Testing is the only way to know. Levels above 100M appear to offer no additional benefit and may carry risk
Instead of worrying whether your peptides are still effective or wasting money discarding good peptides too early, you get personalized protocols with clear timelines, storage guidance, and expert AI support whenever questions arise
But what about everyone else
The practical solution: use a smaller reconstitution volume (1.0 mL) during the early titration phase so the total solution volume is smaller and you draw more per dose (relatively), or accept that you will waste some peptide during the titration stages
USP bacteriostatic water requires 0.9% (9 mg/mL) benzyl alcohol as preservative
Consequently, Heart-failure research reported improved ejection fraction, fibrosis, mitochondrial function, and survival in a pressure-overload mouse model using SLU-PP-332 and SLU-PP-915
