I inject .25ml for a total of 50mg of test cyp Monday, Wednesday, and Friday. I did Sub Q for the first 8 weeks but every time I would get a lump the following day that would last for 2-3 days. I rotated sites all over the place and every time I would get a the lump. Decided to start IM last week and have no issues. I'm wondering how long an interval I should use in between injections at the same site?
