since having problems with the lower backs applying cyp to the glutes has become a hassle. If i am now going to have to apply to shoulders most of the time what is the best size pin to use.? i have a ton of 23 1inch or should i go with a 5/8s or even longers ... As i do have 1 1/2 inches as well. And does the oil hurt more in shoulders then the glutes... Any info appreicate as the only things i have ever put in the shoulders was Winny which hurt like hell and test suspension which was a breeze but this was 10 yrs ago. Thanks guys
