This guide covers exactly how long different peptides last, proper storage temperatures for maximum shelf life, signs your peptides have degraded (visual inspection, smell, effectiveness), differences between lyophilized vs liquid peptides, bacteriostatic vs sterile water impact on shelf life, and specific storage guidelines for common peptides (BPC-157, semaglutide, GHK-Cu, CJC-1295)
However, more research isa needed on the efficacy of vitamin B12 shots for this condition
There is no need to be re-tested
