This question is difficult to reply to. So much controversy, so many differing opinions. I have my own stack of stuff but I've done a lot of research and gear it specifically to my old man needs.
I looked at the Vita-pack label. Looks like there are a lot of vitamins but you probably could get those from almost any good multi-vitamin supplement at a lower price.
Beyond that there is a small amount (by my standards) of BCAAs; Creatine; Green Tea extract + L-Glutamine, L-Taurine, beta-ALanine, L-Carnitine; MSM, Collagen, HA; ALA, etc.
I think the general view on RJ is that it is best to get as much of one's needs met by diet as possible. That usually translates to eating clean, mostly organic, meats, fruits and veggies; supplementing with protein and vitamins as necessary. I think this is a good general rule for healthy, young men as diet is 80% of the goal (lean mass).
Personally I believe that Creatine monohydrate + BCAAs (both in sufficient quantities) is probably a good idea for anyone working out hard. Beyond that you may get a lot of opinions but not much science.
I would suggest looking at some of the supplement recommendations for various routines on bodybuilding.com. For example, take a look at Jim Stoppani's 12 Week Shortcut to Size, Supplement Guide
. There is quite a bit of information there.
Also, once you find sups you prefer and work for you, I recommend looking into bulk purchasing. It is usually much cheaper than any of the pre-packaged stuff. I use purebulk.com but I'm sure there are others.
