I only use Clen stacked with T3. That combo has worked great for me in the past during the final 2 weeks of a cut to shed the last bit of fat that I couldn't shed with an ECA stack (although the "E" in my ECA is from Bronkaid, so it isn't as great as "real" Ephedrine, which is almost impossible to get in the U.S. anymore). I haven't used albuterol, but from what I've read, the half life is so short that you need to take it multiple times a day for any effect. This makes it more expensive and time consuming. I like to just take Clen first thing in the AM before cardio and another dose at 12pm and be done with it (and still be able to sleep at 10 or 11 pm).
