Appreciate the detail here. Your protocol (250mcg subQ near target tissue) aligns with a lot of what the research literature uses. The 5-on/2-off pattern is a common cycling approach.

The gradual onset you described, minimal effect early, accumulating over weeks – is consistent with tissue remodeling timelines. Collagen and connective tissue turnover is slow by nature. 8-12 weeks is often the window where meaningful changes become noticeable.
