I've never done T3 but I'm curious if anyone here feels it helped them grow. Either when dieting or bulking.
T3 is one of my favorite drugs. I would stay on year round if possible, but I limit it to just six months a year. Never had an issue with permanant thyroid damage. My thyroid levels have always bounced back within days.
When I add it into my cycle at 25 - 50 mcg, I always notice a significant difference in gains - both while dieting and bulking (I really don't bulk - I stay lean while I grow) and holding anabolics constant. When dieting, the fat comes off easily with carb cycling and T3 at 125 mcg. IMO, it does not work well with a Keto diet.
I also use T3 at 25 mcg with Clen and Humalog during PCT to maintain gains and keep the fat off. Then, if I want to come off and let my body rebound, I stop the T3 as I hit my next steroid growth cycle. That way it's less likely that I will put fat on as my body readjusts its natural thyroid level. Then, after about six weeks I jump back on the T3 and really see a difference in growth.
