You need to be talking to the Trainers at the Gym or people at some place like General Nutritional Company (GNC) about this, or even some of the other body builders there at the Gym about all this. My brother used to work out and compete against Lou Ferrigno, Arnold S., and others way back but much has changed since then so check. But please stay away from the steroid crap that will build you fast but will destroy your body while at it too. Good luck
I'm a teenager, I find it hard to put on weight. What are some good substances to get (I'm lactose intollerant) I also need something for big muscle gain as I have been going to the gym for about 5 months and can't really see much progression?
I would speak to a registered dietitian about what kinds of food you should be eating to help you gain muscle mass without consuming lactose.
Having a trip to a personal trainer might help you know what kinds of exercises and how often you should be doing them. Like a training plan for you to be doing at the gym.
