I would like to start and say that your diet is going to be the #1 factor to your goals.
I would suggest that you post your current diet so we can help you along more.
Are you keeping one?? This will be very helpfull. It is a valuable tool that you will need to Gain weight. Many so called “hard gainers” are amazed at how little they are actually eating when they take the time to keep track.
Training= Train hard, keep it fresh, dont over do it, and get plenty of rest. If you have been lift in the high rep range for a long time then change it up, go for a low rep strength program or vise versa. Limit your cardio.
As far as supplements. Grow could help you a lot. Liquid calories like this can add up real fast and pack on weight.
Surge. This is a must. Not only in helping you preserve/gain weight, but also optimizing recovery and growth. Slam a serving or two of this down after/during/before training.
You may consider Alpha Male, Tribex, Red Kat, and M. This will optimize T and limit E. I would say hold off on these a bit, and get that diet nailed first. Go with the Grow, Surge, and food as your supplements until then.
As I stated before, post up that diet and training you are currently doing and we will all be able to chime in with much more usefull info… Making sure you are getting all your different macros and such (P,C,F). More often than not many hard gainers short themselves on Fats mainly, then protein, and sometimes carbs.
Get the info. up and lets get it on.
Hope this Helps,
