Hey bros im coming off pct and feeling a little slow, im big on the eca stack but im not liking the otc b/s which is just mau huang or whatever, how can i tell if im getting the real deal ephedrine? Ive used clen and t3 but its just not for me, eca is the only thing i feel comfortable using. i know im not supposed to ask for any sources but if anyones got any "good advice" let me know on the side!
