guys i have a problem. basically ,my tris are way behind my bis and my delts so im going to run some syntherol in them. poblem is that over the years tris were my favorite to hit, and now even if i hit them only once or twice a month it takes like 10 mins to inject 3mls even more sometimes. and this is pushing extremly hard on the plunger. i use 25g 5/8 and also 23g 1 inch and same prob. is there any way to make these triceps muccles virgen like to the needle where it goes in like butter? or anything that may help. thanks
