When I used
test suspension (RWR) once, it did the same thing. I was able to draw it into a 22, but it would jam up every single time when injecting. So what I did was.. and alot of people know about this.. was just draw it, then run the syringe under hot water for a couple of minutes, then shake the syringe hard, then immediately inject. Worked well every time, never jammed up again. I did this with Winstrol (also RWR) too, and it worked well.
Whether this will work with a 23 or 25 though, I don't know. I have also wondered if heating it destroys some of the drug.. not sure.
You know, you can also just drink Winstrol (and liquid Dbol). It is just as effective orally, because it is alkylated just like orals. I have heard that you need to use a slightly higher dose though if it's taken orally. I'm not sure I can believe that, but many have said it.
Hey another thing that seemed to help was drawing in a tiny bit of an oil injectable, to lubricate the inside of the needle.
