this confuses me now, since i am not to familiar with all these acronyms just yet, can you put this is simpler terms for me. Question is, is HCG going to de-sensitize me in the long run?? are there any medical studies or prove to deny this idea? What is E2, ND OP?? i just want to know what would be the BEST thing for me to do for an HCG cycle and when to start it with dosages. WHat has worked for you pharmdoc, cgb, and anyone else?? help or suggestions would be great. Like i said i am going to be doing a 12 week cycle of test-e 250mg 2X week, do you even suggest HCG for such a short cylce? could i recover just on the clomid and nolva during PCT??
