If you ever fear shoulders or quads hit the buttocks and think of none other than FORREST GUMP he got it really bad if you remember in the movie ....isn't that right SGT DAN? Little humor there but yeah cannot go wrong if you fear the sticks in various muscle groups so at least it will leak into the blood stream eventually and you will not waste your money ? PS make sure you use brand new needle as well trust me I was cheap skate in the old days of 1990's and I seriously fealt allot of injections by by reusing.

ffs, no one asking for stats or anything anymore.

Also I always stretch the skin. Then inject on somewhat of an angle in the quads. The sites posted will show where. Always aspirate and switch it up for best results. I like to go quad quad glute glute repeat ...if it's multiple ccs sometimes delts for 1Cc
