This may be a stupid question, but, after having been on pellets for almost two full months as my first TRT treatment ever in my life, will hCG still have positive effects? In other words, can one be on TRT without hCG for so long that hCG would not have an effect?

I'm going to my doc in a week and a half, and I want to try to convince him to start my on hCG before my pellets wear out. I'm about 95% sure I'll switch over to injections after these wear out.

Second question - what is the difference between a subcutaneous injection and a intramuscular injection (I understand these are the two types on TRT injects)?

Thanks!
