So if you frequent the bodybuilding forums and do your research on steroid injections, you may hear about “back-filling insulin pins” to inject with.
Allow me to explain that process to you and why guys do it.
BACK-FILLING INSULIN SYRINGES MAKES FOR A MORE CONVENIENT AND LESS PAINFUL STEROID INJECTION
So there is certain gear with a very short half-life that needs to be injected frequently (sometimes daily). It's not very realistic to be sticking yourself with a larger gauge needle daily, this can create excess scar tissue.
Steroids such as testosterone suspension or Winstrol will need to be injected more frequently. Back-filling insulin syringes is an easier way to do it.
What you want to do is remove the plunger from the insulin syringe. You will draw out your suspension or oil with a larger gauge syringe tip such as an 18 gauge or a 23 gauge.
Once you have 1 ml of oil pulled out (or 1cc) you simply fill the 1ml insulin syringe up from the back end.
After you fill up the insulin syringe with your compound, you put the plunger back into the syringe and push to remove any air in the front of the insulin syringe.
Congrats, you're ready to inject a less painful shot on a more convenient and regular basis. I highly recommend this for steroids such as Winstrol, testosterone suspension and Primobolan Depot.
ASPIRATION OF THE NEEDLE WILL BE DIFFICULT
If you don't know about aspirating a syringe before injecting then you don't have any business using steroids yet. Go research this first, or better yet pick up a copy Straight from the Underground to learn all about gear and injecting!
So unlike aspirating a normal syringe this will be much more difficult with an insulin syringe. Why? Because insulin pins are only 1ml and you're loading 1ml of oil in most case scenarios.
So there isn't room to draw back before injecting.
Not to mention, the size of the insulin pin is extremely small and makes this process even more difficult.
So what does that mean for you? It means that places like deltoids, quads and triceps are better injection areas than glutes. You want areas where the skin is thin and there isn't as much fat to poke through.
The needle you will be using is smaller and shorter, so I wouldn't inject an area such as my glutes.
When I do Primobolan cycles I'll back-fill insulin syringes since the molecular weight of Primobolan is so heavy (this is why primo is most commonly dosed at 100mg/ml) and I'm trying to get my weekly dosage up to around 500-700mg or more.
Although it isn't necessary to inject Primobolan daily because of the half-life of primo, it is necessary due to a lower dosage per mg with this steroid.
I have found insulin syringes to be a great way to inject frequently without the same discomfort of a larger needle.
DON'T GET IT TWISTED, USE REGULAR 3ML SYRINGES FOR MOST CYCLES!
This article isn't for little pussies that don't like needles. If you're using 1 injection per week of straight testosterone for a cycle then use a real God damn 3ml syringe!
This is solely for gear that needs to be injected frequently!
Also know this much; if the gear itself is painful a different sized needle won't make shit for a difference. If it hurts it hurts..period!
