I prefer albuterol because I get all the benefit's of Clem without getting any side effects. Doesn't give me the shakes or a stimmed out feeling.
Phentermine is tricky cuz it's in the amphetamine family so you gotta start low with dosing. I take one 37.5mg pill per day and I'm good to go. It suppresses my appetite just enough and gives me great energy for the whole day. No jitters there either, puts me in a good mood actually
I usually do 4 weeks on albuterol then switch to 4 weeks phen and then repeat that one time. Shit works wonders for me if diet and cardio are on point.
