"Time on plus PCT = time off" is a rule of thumb thats often promoted online. Its a decent outline to go by, but you will only know for sure, by going to the Dr and getting lab work done. You can probably recover a decent amount with 3 months on, especially if you use HCG though the cycle, but everyone is different and will take a unique amount of time to recover. Remember that while using HCG, your body doesn't have a chance to produce it's own test, so you need to be off of it by the time you start PCT. If you want to run it now, for the last month, before you start PCT, I would blast 500mcg about every 3 days up to a few days out from PCT. Remember that it is going to increase your test and is more likely to cause estrogen related side effects, so you MAY need a little more adex to keep the same level os estrogen, while using HCG. You may not, but I just want you to be aware that with HCG, things can change a little. I would suggest using HCG in any cycle. We invest so much money and effort into growing. Why not make the best investment we can into keeping our gains?
