the purpose of pct is to give you a soft landing, not to 'restart hpta'.. there is no such thing so throwing triptorelin or hcg at your body during this time is going to have negative consequences because you will only delay your recover. remember ONLY your own body can recover itself, you cannot force it to by throwing more and more drugs
you may FEEL better using those things, but you are only setting yourself back. it would be like injecting test during pct lol.. makes no sense. of course these meatheads on the internet who never pct'd in their life are all recommending it so it confuses the shit out of people
