Not sure on how much var helps recovery of your torn muscle but my thoughts would be that of course it would because all roids aid in muscle recovery, hence the reason we use them.
Using at the end of cycle to harden up will work.
Using it to bridge to another cycle will also work, but it sounds like your trying to end your cycle and do pct? In that case you wouldn't want the var because it'll keep you suppressed. And tbomb from gnc is not going to be enough to bring you back. I hope that you have more planned and in hand then that.
If not look at getting some hcgenerate, unleashed, post cycle, formastanzol, and possibly nolva or clomid in case you should feel that the others are not doing the job. Although I seriously doubt that you should need them based on all the guys here running the 1st 4.
After a 4 week pct of those 4 products you should be back to norm.
I'm currently running hcgenerate, trs, krill oil, mult vit. And honestly It could be mental but I felt an immediate difference the 1st day on them.
Trust me you need to do a proper pct, going though it with gnc type t boosters arnt going to cut it and you will end up feeling like shit.
Good luck
