I agree with Yong, and also add that bouncing the dose around a ton usually results in pre-shots that are bouncing around too. ECID, but holding a dose for a few cycles has yielded better results for Sam than when I get anxious and start messing with it, trying to chase the pre-shot around. (Doesn't mean I don't still do it, but I know it doesn't work as well as just being patient does). I think 1.4 seems like a good dose for a few cycles. 1.8 was too much. 1.0 and 1.2 weren't quite enough. Which leaves 1.4 and 1.6. If it was me, and I was being patient (hahaha), I would maybe try 1.4 for a few days, and then if his numbers aren't where you want, then try to the 1.6.
