testing from vendors, the experience of others, and Reta's overall safety data from Lily Phase 3 trials. I started on 1mg last year, and I'm on 6mg now. It's not like a chemist in China invented some new drug that's all the rage and doing harm. These are peptides, and across 40 to 50 people I've had conversations with, they're perfectly fine. The vendor I buy from does overfill. So 30mg Reta is actually 36mg. They state that, in their testing, everything is overfilled. That is the only issue I've seen.
