I know the standard needle size recommended for injections is usually no larger than 25. Would 22 be feasible if one were to put pressure on the area afterwards to prevent leakage?

In the cacl2 thread is allthe info, 25G is the recommended. I´ve done with 22 at the start, and no lekage. But the next injections would be more risky doing with 22. Probably this post would be removed and placed in cacl2 thread?

22 Gauge needles risk leakage. Use 25 and up I used 27. You do not want CaCL leakage it will cause necrosis of your scrotum
