test prop 100mg ed

Hey guys After an injection a week or two back my right quad has been a touch sore- not sure if due to the injection or a heavy leg day tweaking it.... Anyway, anytime since when I have gone to inject, I literally can't pierce the skin without a very sharp pain, never mind push the pin into...

Started my first cycle- test prop only @100mg ed, rotating r/l glute and quad. Seem to be more tired than usual, but weight gain wise has been shocking- kept my bf at a steady 12% yet have gained 6lb in as many days. Pulled a new PB on the old DL. How much of this is water weight is debatable...
