174-134lbs. ) I'm hoping to pick up some knowledge here about testing—specifically which US labs are the best to use. Excited to be joining the community. 
I realize your question was directed at the OP, but I've been on Reta since July as well and have lost 28lbs.
A lot of people stick with the dosing used in clinical trials. That said, others choose to start from very small amounts — 250mcg or 500mcg — and work their way up to 10mgs or more, depending on how they respond and what side effects they get. One thing Reta is known for is raising heart rate, which is part of why it's technically more effective at fat burning than other GLPs; still, that comes with risks, particularly when buying from grey market suppliers.
My titration was a little out of the ordinary, I'd say. I began at .5mg, went to 2 after a week, then 3mg the following week, and after that raised it by .5 mg weekly until I topped out at 6. At 6 my appetite was wiped out. I hit a bit of a stall once I reached 5mg, losing only about 1 lb over 14 days, and 6 appeared to get things moving again. Unless something changes, I don't intend to go above 6mg. At 6mg I had some anhedonia, which was rather unpleasant. I'm fairly near my goal.
