what to combine with igf1lr3/sln injections

i'm using BW with my MR lr3, and injecting sln alone (and being damn careful about the combination - i'm bulking anyway). is there anything i can add to either injection without ruining the contents? i'm poking myself a lot, and i would like to combine some of the injections if possible. the likely candidates are HGH, HCG, adequan, test suspension, or combining them together. i think test suspension would be great way to spike your test levels during the crucial PWO period.
