I just ordered a big bottle of P83 (10mcg/spray). I’ll start a new thread when I get it and I’ll test it for a week by itself before mixing it with other products. I may even go back and do a similar week-long isolated test run on P103. I don’t think I ever posted any solo results for it, so I’ll go back and do it. I would do one on P74, but I don’t think I have enough of it left for a week-long run.
