Currently trying to workout 5/6 times a week and want to have the proper supplements for gains the fastest. Currently weigh 172 lbs with 13 % body fat and been lifting on and off. Currently im using Animal Pak multivitamin optimum nutrition creatine powder and pro gainer optimum nutrition. I was thinking of investing in BCCA or BETA-ALANINE or Glutamine . Would that be recommended. Trying to put on mass without spending too much money on supplements. Lean mass if possible. Also looking for a new multivitamin as well; the animal pak has too much pills and I don't feel that much energy throughout the day. I normally work out at night if that information is needed.
