I am going to purhase the clen/t3 combo and but my calories back even more for my cycle duration. I wanted to know if the rapid weight loss has caused anyone loose skin or stretch marks while on either clen or t3. I mean, I already have stretch marks and flab in some spots, I've lost 100 lbs in the past 2 years and I dont think it will make a big difference using this to lose the last 15, just wanted to know. I didnt see anything posted about this. Thanks to everyone for their time.
