I only inject once a week, probably into two different sites, I load up as much as poss, 2.5ml and do it that way. I inject with 1 1/4 blues, this was advised to me by a well known english pro, but I still get lumps. when this happens, i tend to miss a week and therefore my cycle gets screwed.
When I last competed, i got a ***king huge swelling, I spoke to my massage therapist, who suggested docs/draining. I decided to drain myself and took out over 60ml over three days, swelling dissappeared and the tissue appears fine now... I blame winny for that , as I was injecting a couple of vials every day, trying to rotate but clearly something went wrong
I have heard that massage can reduce the swelling, and so will ultra sound (i dont have access to ultra sound though)
