Mexi gear is trash!! Wait, let me rephrase that ... Vet gear from TJ is trash (which is basically all they have available). I wouldn't even give it to my animals, and I'm not even being sarcastic. To each his own though ...
Sadly, its all the rave here in town with the younger crowds. What do they care anyway, huh? They're just looking for some summer muscle. & they only reason it still sells, IMO, is because people don't understand they have choices. I'd say it is safe to say that 95% of all Mexi (TJ) Vet gear is bunk. I see it almost daily. Unfortunately, I've also purchased some of this grossly under dosed peanut oil myself (back when I didn't have choices). I'm sure you might be able to find a good bottle every now and again, but with the counterfeiters out there the likely hood of obtaining a legitimate bottle with adequate hormone concentrations is slim to none.
On top of all this you have the feds to deal with. I'll admit, smuggling juice over the boarder is fairly risk free if your only bringing personal. I used to carry that shit over in my pockets. Even still, last time I checked its a minimum 10K fine. Is it really worth it?
Find yourself a domestic supplier &/or homebrew,
