Hi, just finishing up 8 weeks of cjc/ipa...would like to start a round of tesamorelin. Do I need to take an 8 week break or can I just jump in? Thanks.

Ladies, what are we taking to help with symptoms? I am about ready to have a mental breakdown because I seriously can’t function. I thought maybe it was the peptides I was taking so I quit all but one. I need some help.
