There’s effectively no difference between test E & C. Going to MWF injection frequency will keep your levels more stable than twice a week. Hct, I think, is typically lower on an increased injection frequency but you’ll just have to check and keep an eye on it.
I don’t think there’s any real benefit to going to eod vs MWF once you get rolling for a couple of weeks.
I, personally, consider you dose to be on the very low end of trt, assuming I read you right at 75mg/w. I think, if you’re still symptomatic that bumping the dose is what you need to do rather than just playing with inj frequency. I think injection frequency is a fine tuning option, dose is the main factor.
