How long to leave reconstituted Ipa in fridge before efficacy drops

Bac water with benzyl alcohol is what extends the window. Sterile water (non-bacteriostatic) drops useful life to ~10 days. Make sure your solvent is actually BAC.

30 days is conservative-safe. I've used Ipa out to 60 days in fridge with no obvious efficacy change. Past 60 I toss.

Labs on day-1 vs day-45 reconstituted Ipa showed no meaningful IGF delta in my cycle. Anecdata but reassuring.

Confirmed my bac water is benzyl. Planning to use through day 60 max. Thanks.

One more — don't open/close the vial unnecessarily. Every needle puncture is a contamination risk. Draw the day's dose clean, cap, back in fridge.

Real talk, 30 days is the safe play if you actually care about what's going in your body. The 60-90 day guys are mostly gambling and getting lucky with storage conditions. Bac water helps but it's not magic, peptides still degrade. Cyclecraft nailed it on the punctures though, that's actually the bigger risk factor than time sitting there.

Yeah dr_doubt's right, the puncture thing is way underrated. I've gone to 60 days plenty of times with zero issues but honestly I think half of that is just luck with my fridge temp staying consistent. 30 days and you're not sweating it, past that you're rolling the dice. The peptide itself degrades slower than people think but bacteria loves a punctured rubber stopper so that's the real wildcard.
