I've been doing stuff when I'm ready to use it, but I've so considered the kinda-sorta- @indolent method. Since a 75-day course of KLOW (two GYC vials) takes 24 ml for me (cause I recon it weak to keep from bruising), I've thought about using the last 6ml to recon tirz. At 22 mg/ml, that would get me 132 mg of tirz (about four vials of 30) and last me 16 weeks at an 8 mg dose. I could freeze the vials not in use, and one bottle of bac gets used less than 30 days after it's opened (assume I recon the first vial of KLOW and the tirz on the first recon, then the second vial of KLOW to use the remainder 38 days later, since KLOW may degrade faster)
(indolent does a kit of tirz at a time and freezes, but that's too much committment for me; what if I switch off tirz and go to reta for years?)
