I've seen the question asked a few times. Not sure I've seen a answer. I simply stopped IM and went right to subq without even thinking about this. I got crushed, more or less felt like I quit trt cold turkey. I think I fell into the not a good subq candidate with poor absorption and slight allergy to cotton seed oil when injected that close to the surface.

Subq is a definitely a cake walk compared to the IM and I now know I might have been injecting into too fatty of a area. Perhaps I can retry in the future.

So is there a correct way to do it? Start at 3/4 IM and 1/4 subq and slowly advance each week? Maybe a blood test in the middle to make sure your not crashing?
