so i am 23 have been working out for around 5 years. I eat a lot of protein. i am 6' 200 pounds. I have tried stuff like no explode and it didn't seem worth the money. Now i just use energy pills before a work out and protein powder. But i want something to help build muscle. I don't want to get into anything illegal. I am looking for a simple supplument that helps build muscle. I was thinking osta. But is that only for PTC? can i just take some and get good results? Is there anything that is not a RC that works?
