I know this post is waaaaaay late compared to others, but I want to throw my $0.02 in for those researching doing Clen. 1st off I received my Clen from a very trusted and reliable source, not an issue, he's a med-student and works in the lab. He takes this too.
I am on my 2nd day of this stuff, I never needed this kind of thing till lately due to some surgeries and family emergencies, over the past year I have laid around a lot compared to what I usually would do. Needless to say, I am out of shape and untrained. I get to the gym whenever I can, but it usually ends up being pushups/etc and yoga. Active, but not what I want.
Clen makes me tired as hell, and irritable as hell, it makes my vision kinda fuzzy like sleepy. I took EC stack till the other day and felt fine, no appetite. Today and yesterday I ate so much more! GOD! (so much more). So EC stack reduces your appitite and burns some fat, but it seems that the Clen boosts your metabolism up so much that you gotta eat and be very active or you will feel sleepy. This could be a plus really since you need sleep to regenerate cells,etc. So maybe I could take the Clen closer to mid-day and not in the morning.
Now, I walk the same mountain every day. Since i've been on Clen, it is difficult, my body is exhausted, not just my muscles. My question is this: Is it really worth it?! I lost 40lbs a few years ago by bustin my nutts in the gym lifting weights and cardio CLEAN, no drugs. Now this Clen seems like a good idea, doin my cardio, getting my weight down. I lost 7lbs in 2 weeks on EC stack, I am giving Clen 2 weeks and will report back. But, honestly, I may skip out and go 'au-natural'.
So, the moral of the story is this, it isn't for some people. I depends on your goals, your age, your health, your $$ situation, your ethics, and your family. I have a supportive wife who was cool with Clen and not Sustanon. Its all in the eye of the beholder.
