With 21g and Jurox 100mg/ml Suspension, More ofter than not it jams in the needle when in my ass, then only to go flying in the air after I remove and try to expunge. Do you need a bigger needle, like 19 or 18g?
Putting a 18 gauge needle in your glute or anywhere ED is not going to be pretty. I've heard of people putting an oil base AAS in the test suspension and shaking it a little. I heard Jurox hurts like a mother, too.
