Does Opened Test Lose Potency?

[Oldguyjiujitsu]

I know unopened pharma test is good well past its expiry date, BUT once you flip off the tab and take a few pins, does it lose it potency after a period?

Reason: I found a 1/2 used vial of test in my cupboard that had fallen behind a box of pins. I suspect its been open 3-4 months. Still as potent??

I think you're g2g!

as mister @ClearWater says your g2g

now if its much older and your worried about it being safe ie clean to use then ask me for my handy dandy method to make sure its sterile

You are most certainly OK to use it.

Definitely g2g. I had a half a vial of Test sitting around for over 6 months and when I started cruising thats the vial I started with and it was perfect.

Had a vial of british dragon andropen 275 from 2008 I used last year and it was good to go!!

No problems with that, it’ll degrade in time but not in months. I’m currently using some delarestryl that expired 4 years ago and it’s fine.
