The preservation of peptide stability has been observed for at least 28 days after reconstitution.[15] Peptides stored in Reconstitution Solution maintained 98% activity in assays up to 14 days post-reconstitution.[16] 2.3 Microbial Control & Aseptic Handling Benzyl alcohols bacteriostatic action has been well documented in pharmaceutical formulations, especially in multi-use vials, which ensures that peptides do not become contaminated during the study period.[17][18] Multiple use vials of Reconstitution Solution for research have shown reduced microbial load, even after repeated sampling.[19] 2.4 Storage & Stability Considerations While Reconstitution Solution extends the shelf life of reconstituted peptides, its effectiveness relies on proper storage conditions

Moreover, the same authors performed a similar study introducing DR in late-life which confirmed that fasting even in late-life increased protein persulfidation in the liver, kidney, skeletal muscle and brain, although not always to the same extent as mid-life DR intervention

Whether that translates to your specific goal is a question that honest research cannot yet fully answer, and this guide is not going to pretend otherwise
