I recently started test susp and had never used it before. I had the same problem with it clogging the needle both times I used it. Unless this has happened to you, you don't realize how much it sucks. I had to re-pin my quad and then my leg felt like hell for about 4 days. So much so that I'm prob not going to pin in my quad again. I thought the new needles I just bought might be the prob but know I know. This is really good advice. I will try this next time. Thanks.
One more quick question about test susp, does site injection work? If you pin in let's say your left bicep will your left bicep get bigger? Just curious. I've never pinned my bicep b4 and wouldn't even know the proper method.
My right quad does seem to be bigger from the injection but it could just be swollen.
