First off, what are your stats (age,height,weight, bf%)???
Second, doesn't matter where you inject, it all goes in you the same. Delts, quads, lats, etc... all the same one inch pin for all, except 1 1/2" for glutes, 5/8" for biceps and shit if ya wanna get silly, theres no need for that shit!
I do delts and quads with 23g x 1"... some say thats too big, except im fine with it id rather have a thicker needle than have a 25g break off inside me, guys on here will argue this, but i like 23g, just feel more comfortable with it...
But you have to give us stats before you go any further, and you do not need anadrol, that will bloat you, fuck your liver up and drops out of your system fast... fuck anadrol.... just give stats and we will help
