It's been years since I've used it. MA had it then, I'm guessing they still do. Liquid was nice for adjusting dose. I split it 2x per day and started really low like 10 mcg x2. After a few days I'd up it, and again, and again. I maxed out around 40 mcg 2x per day for a total of 30-40 days or so.
It made me pretty shaky and jittery. I didn't like it and can't say it was much more effective than a good natural stack. I wouldn't use it again unless I had to get my bodyfat well into single digits.
