Just wondering what people are generally using. I have slin and 27G pins. I could see using slin for bi's/tri's/pecs/lats but if I do 20mcg in both sides, I don't know how I feel about using a slin needle on my glutes and other areas. What's everyone else doing?? Also, how often can you come back to the same muscle using the new mix? Thanks!
