Just figured I'd post my experiences with this product. I've done one run with clen before and they were pharma grade pills. Started off with 60 mcgs a day then worked my way up to 120 mcg a day for 2 weeks. I'm 4 days into my clen, and let me tell you its the real deal. I decided not to taper up and just start off with the highest dose I was comfortable with which was 120 mcg split into 2 60 mcg doses a day. I wake up and take the first 60 mcg and it literally has my hands shaking like I have Parkinsons. Stuff feels stronger than the pharm grade clen I used.
