Backloading Slin Pins: My Method

[phenominal34]

Maybe next time that’s what I’ll try. Not sure if it’ll work for backloading 0.3ml into a 0.5ml syringe since that is more than half of the barrel. A bit of a loss is ok with me though, I’m only concerned about possible bacterial growth, AAS is cheap lol.

Get 1ml syringes …. Extremely cheap in order to save oil and be safer

Thanks for the suggestion, I’ll check if there are any slin pins with 1 ml barrel. I still have a ton of 0.5ml left though

I've done effectively the same thing before, its a little tricky but just keep a steady hand and wait for the oil to settle on the plunger before pushing it forward.

Why backload? Seems unnecessary. If your oil is warm it flows right in a 29 slin from the vial...in like 5 seconds.

Yes but def dulls the needle and at least I can tell a big difference. Fresh needle glides right in skin, one used to draw first ya gtta push it hard. That’s just me …

Yeah and if it’s two compounds then even worse. Plus it allows me to prep during weekend and just pin quickly after.

Isn't just using a draw needle and injection needle less work than all this?

It's more for when I run multiple compounds. Pushing a slin into three different vials is like trying to inject with a mechanical pencil by the end. You could use luer locks, but I hate the dead space and can't always find my favorite gauge needle tips.

Plus I like to get my prep work done on the weekend, then not worry about drawing in the morning. I bounce back and forth between my place and the gf's, so I can just throw my pins into a pouch and have em good to go for the next day

They just like to make things complicated.

Brahs... just buy some 3ml syringes and slinn pins. Have both on hand. U can use the same 3ml syringe for 1 or 2 weeks to fill your slin pins. And when u do higher doses u can skip the slin pins and just use the 3ml syringes. Jesus

My supply....

100pk 3ml syringes
100pk 26g luer lock needles
50pk 21g luer lock needles (for drawing)
29g slins

I Backload 1 slinpin the day of injection. Takes fucking 1 minute.

I mean, it also works. I see no difference in preloading one big barrel and storing it vs. a few small ones except a bunch of small ones is a bit faster on the day of the pin. I also tried my 25g luer lock syringe today for the first time and it def isn’t dead space :/ maybe I got the wrong needles.

I think you meant def is deadspace?
You got the right ones u have to use the airlock method to avoid the deadspace.
So load .1-.2 ml of air in the syringe hold the needle so it floats to the plunger then inject and the air bubble will push out the rest of the oil.
If your doing it this way take into account the dead space when drawing also I believe 25g 5/8 are .05ml dead space

Oh I thought deadspace needles meant they don’t have any space between the plunger head and the needle. My bad.

Mine is 25g 1” 1ml. I do admit that I’m a noob when it comes to needles etc.

It's definitely something people don't think about at first.

Yeah my slins are #4 in the pic, and 25g one is #1.

I got bashed in my post for storing oil in syringes as the rubber of the plunger seems to degrade somewhat from the solvents
So Idk it seems there is a divide on meso about this but the fact is solvents do in fact react with the oil, the question is how much and is this a real concern...?

my reduced dead space needles leave 0.05ml per inject inside. a full standard syringe is about 0.1ml and if i feel seriously aggrieved by that, i just put half the nozzle of an air bubble in the syringe behind.

tbh, all this fuck on for 0.05 or 0.1ml backloading syringes is not even remotely worth it for me.

When I'm cruising idc as much I just put in an air bubble like you said but I do daily pinning when I'm blasting so the loss adds up fast.

Ok, only for the Hardcore. No needles needed. Jet injection.

I don't store the oil in the syringes. I just draw 1ml with a 3ml syringe and fill a slin pin everytime i pin with a slin pin.
