So I was injecting only 1 ml of 100 mg of prop into my shoulder today, following good injection procedures. Wipe the area with alcohol, inject deep into the muscle (25g 1.5 inch), pull back on the plunger, then slowly insert the oil (took at least a minute). When I pulled out the pin no blood came, but the juice started to leak out. I bet I lost a good .3 ml. I have heard this happening to people who inject too fast, but I have done at least 10 cycles and this has never happened to me before. Any ideas why? When it started to leak, it wasn't like it was dripping. It rushed out.
