Thread: Back filling SLIN PINS

I really need your feed back on this subject:
I want to know if I can back fill a 1 inch needle - 25,27, or 28gauge, 1cc insulin syringe with a cottonseed or sesame oil based testosterone cypionate and inject it into a muscle group easily. The reason I’m asking is because it takes forever to even draw out and slow to inject with a 23 gauge syringe. Any experience with oil based injections appreciated.

Backloading. Yes? Why not? I do it all the time.

I ask because in the past I have only traditionally used a 22 or 23 gauge needle with my thick ass testosterone from the pharmacy. I have used 25gauge for home brew/EO/Private label stuff and it works great but when I draw the test cyp from the pharmacy it is sooo thick and I would love to use a 25g or higher gauge. Would make my weeks go better!

You can warm the oil up in a warm bath water to thin the thicker oil out

I do it all the time with oil, just not the one you mentioned. I draw with 21 gauge and pin with a 29 gauge. I also pin daily to keep the serum levels consistent.

Very good point. I’m in SoCal and do not have the cold temps.

Crashing? haha


I usually just leave my vial in some hot water for about 5 minutes before drawing.

Warm the oil for an easier go of it
