i have 200cc of synthol without the collagen. using for biceps and triceps what type of gains can i expect. i have 17" arms now. one year after last synthol shot how much size can i expect to keep?
I agree why would you do synthol. It doesn't make you anystronger and the size you gain is basically like filling a ballon with helium eventually it's going to deflate. The only use I see in sythol is for brobodybuilders who want to look a liitle bigger at meets.
