+ 1 Frontloading vs Backloading
ad
I know a lot of you run multiple compounds at the same time, if you're injecting them all separately you must be looking like a pin cushion by now...
So I'm just curious how many of you are strictly frontloading your syringes or are you backloading as well? And which do you prefer?
Anyone had any bad experiences from backloading?

When it comes time for my blast (test +dhb) I will be mixing them in sterile vials then just drawing up with a 23g and pinning with a 27g.
If injecting my ass I will frontload whatever compounds with a 21guage same needle for all draws. Then pull back the plunger enough to suck the juices down into the barrel "no homo" , switch to a 25 guage 1" tip and push that bad boy in my ass.
If pinning my delts I draw with a 21 guage 1" and backload into 29guage 1/2" slin pin.
Lmao bro the way you described that was spicy I’d thumbs up you but I’m out right now.
Actually, my wife is the one that sticks it in my ass
This is essentially how I do it without using nano/microsyringes

I only front load and with my medical background that is all I will do because back loading can cause sterility issues.
babe I need you to backload me
Babe you are the only exception, You are going to get a GIGANTIC back load of high quality testosterone.
I front load. Sometimes when I try to pull from mulitple vials pressure or whatever else causes issues where I need to push some compound back in to get it to flow better. This causes issues when I have a few compounds. I don't want to contaminate my NPP with Test etc etc. So I just Draw up my Test in one Syringe. Unscrew the pin from the main syringe and then use another seperate insulin syringe to front load the main syringe I use.
Whenever i try to backload damn pressure or air gets trapped and shits squirts out the tip. ;)
One 27g insulin pin. 3-5 compounds. One shot.
Currently running primo, mast, npp and prop. All together they add up to a ml. Heat them up for a minute on a candle warmer to make the oil more vicious. Simple as that.
yup that's what I do. Takes awhile to draw the oil but other than that I haven't had a problem with it.
I'm not really too sure what you mean here mate?
I inject daily so simply draw up some Test Prop, NPP and DBol inject into the same barrel measuring each to the amount I want on that particular day. Then the days where I want some Enanthate which is twice per week I'll add that too in there so on any given day there will be 3 or 4 compounds in there.
So you're frontloading it using the same needle to draw up all the different compounds into the same barrel?
I'm just seeing how everyone else is handling multiple compounds, loading them through the needle (frontload) or taking out the plunger and loading it directly into the syringe from the back (backload)
Trying to see if I can do anything differently or get any ideas as I'm currently just frontloading from multiple vials takes a bit more time to sort it out before pinning
If you warm up the oils a little they will load into the syringe a lot quicker.
Jrihard89I just run a 23g and it’s easy as pie with thin oil.
The back loading sounds gross and doesn’t sound sterile
Yeah buddy - I do it like that.
I find that making sure you measure the barrel out during the day by holding it against a daylit window is the key to doing it quickly, when its night time and the barrel markings can be harder to make out when measuring multiple compounds it can make it a pain in the arse. I guess you could load up a vial at the beginning of the week but sometimes I will want more of a compound than on other days - half the time I won't want DBol inject in there either so I prefer to have the flexibility in what I want to pin that day.
Go Multi-compound or go home LMAO
When I’m blasting with multiple compounds, I honestly don’t like frontloading or backloading syringes for multiple days. Too much room for contamination and dosing mistakes if you’re running a lot of gear.
What I’ve been doing for years now is a bit different. I use calculators, sterile filters, and empty sterile 20 ml vials and basically make my own blends.
I separate whatever I’m pinning into those vials and build it according to the protocol. If it’s daily pins, boom … one vial ready to go. If I’m respecting different esters, I’ll split things into 2–3 vials depending on the injection days.
If the dosages change during the cycle (which they usually do as weeks progress), I just prep a new vial with the updated math and keep rolling.
For me it’s been the cleanest, safest, and most accurate way to handle higher-dose protocols with multiple compounds. No pin cushion, no juggling 5 bottles every shot … just simple math and the right tools.
That’s the system I ended up developing over the years and it’s been working great so far.
I just bought a case of 10ml sterile vials for exactly this!
That’s the way to go, big bro! Give it a shot and see how you like this approach.
This is the way.
Fastest, easiest, and safest way for multiple oils in my opinion.
FYI: @Waltdisneysbun
Peptides are another beast and shouldn’t be mixed. But I know you were asking and I’m pretty sure you know this, but just in case.
Smart
That’s the way to go, BIG. Give it a shot and see how you like running it that way.
If running multiple compounds, I draw them all up into a 10ml syringe, warm it up and shake it real good, then divvy it out between 1ml barrels. I cap those and store them upright with the plunger pulled all the way up, so the plunger isn’t sitting in the oil. Then each morning grab a barrel, a new luer lock needle, put it together and plunge away. Usually premake a week at a time.
I've never thought about pre-prepping them to be honest, would save a lot of hassle and syringes compared to the way I currently do it lol
Ever had any concerns about the 'sterility' exposing the oil and stopper etc to air during all the prep?
I've never really understood the argument about it considering we're pumping air into the vial before drawing
I just keep the vial order on a set rotation. Whatever vial I hit first that day gets 1 mL of air, and I only do that on that one vial. Since I never draw more than 1 mL per day from any single vial, they stay balanced and don’t develop that annoying vacuum that sucks the pin back. Keep the rotation consistent and the vials stay pressurized, which makes draws smoother and helps avoid bubbles.
Not at all. The barrels are sterile. I wipe my workspace down with isopropyl alcohol before doing anything. I pull the plunger back and load from the luer lock tip. I just stick the needle of the 10ml syringe down in there and put however much oil is needed. If the oil has the appropriate BA content it’s not gonna grow anything in there. People get infections from pushing bacteria down into their skin via the needle. That’s why you wipe the stopper and the skin. You don’t disinfect the oil each time before drawing from a multi use vial.
