First time inject with 3cc...yes you will hurt for sometime...you stretched the muscle facia and fibers out...it will take a bit for 3ccs to be absorbed through the muscle...especially the first time. you need cannonball delts for 3cc
should have done 2 in hte ass or thigh and 1 in hte shoulder...well there are many different ways you could have done that...that is just one
If you are going for 3 cc in each delt. Make sure it is even use 1.5 on the top part of your delt . Then 1.5 on the side of your delt. A good trick is to mark the area in the mirror first . Or you can make one biger then the other. then go to 2 cc on each part. Yes it will hert but its wrth it. I have put up to 10 cc in my calfs at once useing 2 cc in each spot. 5 locations. Know that herts but it works.
Im currently injecting 3ml ED (primo, tren, winny) and rotate my shots between delts/bis/quads. 3ml in the tricep seemed a little uncomfortable but i jab 3ml in my delts/bis no problems using a 23g 1"
