Is there a way to test whether Tren Ace is legit? I got several bottles from a source that’s always been great but this time one of the bottles doesn’t seem quite right. I used half the bottle and then just switched to a new bottle. The new bottle seems to be great. Everything I’ve used from this source has always given good results until this one bottle. Thing is I have a lot of this stuff from the same source and I’d like to know if it’s just me or if something is wrong with it and I’d like to test the rest of what I have. This source has been good to work with and they’d probably comp me some gear if I complained but I don’t want to complain unless I know what I’m talking about.
