alright guys i got all my gear coming for my cycle, whats the deal with the needle exchange, i searched the threads and needle exchange site but i thought id ask here 1st so i dont look like a mug when i go in there. do you just write a list and walk in and they give it to all to you?haha .... also what size pins do i need, im going to inject each glute once a week with 250 mg test e on sundays and wednesdays, i dont have loads of meat on me so do i go with 1 inch or 1.5? all the threads say something different and i cant decide ... also it will be my first time injecting shall i use the same needle only once?
