Taking the advise of many members on this forum I started using the 27 gauge 1/2" .5ml insulin syringe/needle combo. I think this is the perfect size with no pain no blood and the syringe quickly fills with Cypionate. It also injects very fast and I could not feel the needle in my thigh. I inject every five days and recommend this syringe/needle combination for those who inject into the thigh.
