if ur looking to put on weight, uve got to look at the calories u burn everyday, compared to how many u take in. Myself am very active and need to take in 2700 calories a day just to maintain my weight. I lift 5 times a week hard in the gym. Yes i do use a supplement, size on, its a creatine form, and to be honest ive been taking creatine on and off for about 2 years now, and if u use it correctly i.e. cycle drink plenty of fluids its perfectly fine for u. I also take a weight gainer and use it as a protein as well, 1020 calories per serving with about 70g of protein. Ive taken a test booster before, and i wouldnt recommend it, its a waste. I take that after each workout and sometimes if i miss a meal. I also eat like a fuckin horse but not shtty fast food, i eat loads of grilled chicken, rice, peanut butter, beans, high protein foods as well as lots of carbs to keep my weight up. I take in generally anywhere from 3500-5000 calories a day, and i am 5'10 166lbs, benching 250 4 times on my 4th set in bench, starting at 225 after my warmup. Alot of putting on muscle and staying lean is all about having the correct diet and eating right. U can eat like shit and gain fat if u want, but its just a waste of calories. Cut out any soda in ur diet, drink lots of water. A few member on here can vouch for me, ive made more than a few workouts for members on here, and they gave me some positive feedback on how it has worked out for them. As far as my workouts go, i usually do 2 muscle groups each day, but i change my workouts every 3 weeks to keep my muscles guessing and not plateauing. For instance, i usually do chest with biceps, back with triceps, shoulders with legs as well as traps. I will do atleast 4 different workouts for each muscle group, and if i want to gain size i will usually do 4 sets of 10-8-6-4 reps. Abs are done about 4 times a week, core strength is so important for every other workout as well as lots of daily activities. There is much more to be said, but if anyone has any questions feel free to ask in here or PM me for answer ill help anyway out who is looking to better themselves. Yeah i know my grammar and spelling are shitty but idc because its the interwebzzdcnasdjkvnlolz
