I think for SQ (belly fat) you'd be fine. For anything else I'd use at a minimum a 27 ga 1/2" pin. For low volume TRT doses it'll work fine anywhere. Doesn't matter if it part SQ and part IM. It all absorbs.
Ok sounds good. Thanks bro..
Now do u think sust will work just fine for trt or would a solid ester work better such as e or c.
