Best way to keep Reta good?

The T-20 convention gives clean 1mg-per-10-unit math which makes dose tracking straightforward. At higher doses the dilution math starts to require more volume per injection, which is the practical point where reconcentrating becomes worth considering.

Keeping unmixed reta refrigerated extends the window reliably - 60-90 days at 2-4C is what most people find workable, and introducing cagri once the reta dose is stable makes the stack easier to dial in.

Powder in the freezer, then 24hr room temp acclimation before reconstituting, then refrigerated for active use is the standard protocol. The cycling between states doesn't degrade the peptide the way rapid temperature swings do. The 24 hour step before reconstituting is the part most people skip and it matters for consistent dissolution.

11 weeks on a reconstituted 40mg pen without noticing degradation is a useful data point for how forgiving the storage is at fridge temps. the degradation question is hard to answer definitively without testing but the subjective experience of consistent effect over that window is about as good as most people get. any changes in reconstitution approach or just same process throughout?

Answers will vary a lot depending who you ask. Personally cap it at eight weeks and never run into issues. Probably could push further, just never needed to. Current buying quantity lasts about four weeks anyway, so keeps things simple.
