Ok, the question that first comes to my mind is what gauge and length of needle are you using? For quads I personally use no greater than 25 gauge (smallest necessary for oils) and 1 inch. Now let me tell you that I have been injecting every week for the past 8 years. Let me also tell you that my injections are always painless. My recommendation is that you rotate in the glutes for your injections. For those Deca and Sust I go ass cheek to ass cheek every 5 days and thrive on it without any pain whatsoever. For some reson, for me, very clean injections of body temp oils with a fresh needle of 25 gauge and 1 inch using a band-aid with antibiotic ointment afterwards is the perfect stick, Never a problem my friend. Now for all of yous that are now going to spout off telling me that it's too much trouble or whatever bla bla bla that you may come up with, I am right, you are inexperienced. I am an old guy, in awesome shape and very educated in this. Listen up my friends.
