Just to weed out the "eat a healthy diet" response, I'm a 23 yeard old 6'0 225 around 10% body fat ex-football player. I've been eating healthy for years, but because of a high metabolism, I have had considerable difficulty gaining weight off of diet alone. I have read that an athelete should take 1.5-2.0 x your weight in kilograms of protein a day in order to bulk up. My kg weight rounded up is roughly 103kg so about 200g protein a day.

I'm about to start a bulk stack to try and reach that level a day. I am looking for a between meal, or throughout-the-day supplement to help me gain muscle mass. I will be doing HST training. What's a good through-out-the-day supplement to help gain size, not necessarily as focused on strength. Also, inputs for those who have taken these supplements are welcome, or if you have a reccomendation for one that may be better than the ones I have posted.

Pre-workout: Pump Fuel (wanting to use a non-caffein pre-workout)
Post-workout/recovery: AfterGlow
Mass Gainer: suggestions?

PLEASE do not answer with "eating a good diet" type answers because through experience I have seen that it is simply not enough for my metabolism

sidenote - I want to stay away from any roids
