i use a 22 gauge 3cc syringe to extract than pull the plunger from the slin pin and use the 3cc syringe you have to pre fill it to w.e amount you need most don't exceed 1cc in slin pin than turn it upwards push the air out and boom pin easy and the needle hasn't been used once so nice and painless.
Right now I'm just testing out some new tren-e. I'll start my actual 8 week cycle next month. Even then the quantities will be fairly mild. I'm thinking I'll inject 100mg test-c and 100mg tren-e (total 1ml) Mon, Wed, Fri. A 27 gauge 1/2 inch 1cc should work well for this. So the cycle will be 300 test and 300 tren for eight weeks. Maybe a week or two of low dose dbol to start.
I've done a lot of oral cycles while I was on transdermal test. Doc just switched me over to test cyp. This will be my first cycle with oils so I'm just easing into it.
IMO 1/2 inch just doesn't go deep enough..especially if your pinning glutes. 1/2 slins are intended for sub-Q injections not IM. A good portion of the gear may not make to your blood stream. And you certainly dont need to pin cyp and tren e 3x week.
Get some real pins..say 25g at least 1 inch..and some 18 or 20g drawing pins...and pin 1.5 ml 2x week.
