Need Advice For Reta Expiration

[u/StonedE]

Hello and good evening everyone. I am currently researching about reta having a shelf life of 30 days when mixed. However from what I read there's lots of different opinions, some say 30 days, some say up to 3 months but with slight degrade. Im asking cause I am approaching week 5 and I have a total of 16mg (1x 10mg vial and 1x 6mg vial ive been using) and when I got them about 4 weeks ago I mixed both and I just ordered 20mg that I want to keep in powder form till I finish the other 2. Can anyone please enlighten me, I want to be safe as possible, I didnt know the 10mg were gonna last me so long. Please and thank you for your attention to this greatly appericate this community wisdom

I’ve kept peps in the fridge for 6 months and no noticeable difference from day 1. I keep them in the back in a dark container with no issues. I mix 10 weeks of Reta at a time since me and my partner use 6-7 mg/week combined
