Are you choosing between 2 mg every five days and 4 mg every seven days? After six weeks at 2 mg you can safely move to 3 mg or 4 mg. I would simply raise the dose and keep the weekly schedule rather than stay at the same amount more often, especially if you want to increase the overall effect.
I started Reta six weeks ago at 2 mg as my first dose. This week it feels like the effects are dropping off and my body is adapting, so I’m considering moving up to 4 mg. I’m also beginning an aggressive cut tomorrow because of an important meeting in a month; I’m at 15 % body fat and want to reach 12 %. I’ve been injecting every Tuesday night and am now thinking about switching to 2 mg every five days. What do you think?
