I posted in Supp forum, no response..someone has to know.
I normally run an ephedra free fat burner when not taking albuterol, clen or ECA. Thermogen II are cheap and effective, however, it contains Yohimbe. Does prolonged(longer than 2 weeks) use of Yohimbe downgrade the same receptors as eca or clen, or another receptor? Or no receptor at all and safe for prolonged use?
