Welcome to the boards.
Cannot really comment on the supps. As to your injuries, you state that you have been working out, on and off, for about 5 years. You may be getting injured because each time you return to the gym you try to lift where you left off. You need to give your body at least some time to acclamate itself.
I was in a similar situation. Trained for several years, then school, etc. made me train sporadically. Career (desk job) with long hours and a healthy appetite

helped in putting on weight on my midsection. Started going back to the gym religiously, but made sure to take it easy the first two weeks before moving to moderate weight. By my forth to fifth week I was lifting as heavy as I use to in most exercises.
Also remember to listen to your body. I woke up one morning with a strain on the lower part of y biceps. So what do I do? I go to the gym and hit arms

thinking I would work through it. Thankfully, I did not injure myself but did make the pain worst. So laid off for about a week and it sees fine.
So remember to take it slow in begining and always listen to what your body is telling you (except of course when it comes to eating which may get you into trouble

)
Good Luck
