You're a beginner and beginner's gains are better than the best supplement regimen - it's free, so make good use of the adaptations. Supplements will not be the key to success insomuch training, diet, and sleep will.
As far as supplements go, I spend a significant amount of time every day reading pubmed and forum information in addition to conducting my own tests - primarily because this is fun to me, not necessarily because it is productive (they are, after all, just polish/gravy, not the path itself). I think its important to fully understand what it is and why you're taking it, so if you're going to play with supplements, read everything you can get your hands on.
That being said, there's a number of easy/beginner/ridiculously well-tested, safe products that don't break the bank:
Creatine Monohydrate - it works.
Caffeine: All day err'eday.
Fish oil (lending my own expertise here on joint pain: the best deal appears to be Walmart's Spring Valley Triple Strength, 3 caps/day)
Probiotics: I use Evomuse Gut Health - this is easily the most dramatically effective supplement I've ever used.
Digestive enzymes: NOW brand - this and the probiotics will be very useful on a caloric surplus for your bulking. Eliminates farts, gurgles, bloating, and mitigates a lot of the unsavory effects of eating far too much hot sauce.
I knew if I brought down the weight it wasnt gonna be good. I had this same injury about a year ago and never thought it would come back. Gonna take 2 weeks off chest so I can at least return to regular sets. Pretty sure I strained my chest again
