want to think the members who gave me some ideas on how to inject testosterone propinate with out crippling myself for a week, not sure which idea worked maybe it was all of them they were all good. I warmed up the test ( that was one suggestion another was get it deep in the muscle so I used a 22 gauge 11/2 needle ( all of it) worked it in for 3 or 4 minutes and another suggestion was to mix it with some other gear have had 2 injection very little pain thanks again
