dont put your gw-501516 in the fridge

Putting them in the fridge after being mixed keeps them from deteriorating. In the dry state they are fine for several days. But once you add your bac water, or whatever solution you use, best to keep in the fridge. Usually if left out just for a day the potency is very weak if not nil.

Oops just realized we are talking research chems, thats my adhd kicking it and just throwing out an answer. I have never used research chems, in regards to PCT. But being liquid, I would throw it in the fridge after first use. Even if it doesn't break down the chemical to leave it out, you still have the chance that airborne bacteria might sneak in.

Research Chems?
