protien bars are a crappy source of protein. at least 60% of your daily protein should be coming from whole foods: egg whites, cottage cheese, chicken breast, lean red met.
for the remaining 40%, try to get it from whole food, but any extra you need should come from a quality shake/powder, not a bar. Only a few bars out there are worth a damn, and they are 4x the price of a protein powder. All you need is a shaker cup and access to water to make a shake.
Never heard of HUMAGRO...just googled it, and it appears to be one of those rip-off, fake Human Growth Hormone supplements. Don't waste money on that kind of crap. There are relatively few supplements that actually work like the claims say. You can only get HGH from a doctor or black/grey market, at least in the U.S.
The only supps you need to bother with are: multi-vitamin, protein powder if you can't eat it all in whole foods, fish oil capsules (for Omega 3, 6 and 9), and creatine monohydrate.
Definitely don't bother with fancy creatines, L-glutamine, or anything that is a "Nitrogen/Nitrous Oxide/NO2/Hemo-dilator" because they don't give you any real gains, and shrink the pocket book. Also, no tribulus, and skip any 'pro-hormones' and 'pro-steroids' ...because the ones that actually worked have been banned.
If you have trouble sleeping soundly at night, you can take ZMA at bedtime, but avoid anything containing calcium the hour before & after you take ZMA as calcium blocks zinc absorption.
