Daily Pin Prep
ad
I just got done prepping my syringes for my daily pins for my work week from Monday to Friday to reduce time spent in the morning. I am using 3 compounds at once so drawing the oil up in the morning feels like a hassle and thought prepping them ahead of schedule was a smart move.
Does anyone else do this to help save on time, or do you think its not worth it, and not worth possible contamination?
I don't see how it could get contaminated if you are practicing the same hygiene, but I've seen people argue it?

I prep peptides an entire vial at a time because it’s stored in the fridge so contamination is less of a worry for me.
I prep oils the night before but in the past I have prepped oils a few days in advance when my schedule was really crazy. I’d feel comfortable prepping oils up to a week in advance in really dire situations but I don’t if I don’t have to.
I’m running three as well - .4ml primo, .3ml mast prop, .25ml test - but I find to draw each into a single syringe (.95ml total volume) and pin it takes less than 2 minutes so I don’t bother prepping them in advance.
I just do mine the night before. I prep my supplements and oil for the next morning. Doesn't take too long
Makes sense and can work, but at night I just don't feel like it at all lol. I only have enough energy to eat, take my bedtime stack, and pin a bit of GH and that's it.
I backload my insulin syringes for like 5-6 days at a time, takes like 45 min for all 3 compounds compared to straight up loading every morning which takes about 20. Becomes like brushing your teeth every morning when you don’t have to load every morning. Game changer
I make a blend and put in a sterile empty vial, then backfill slim pins for daily, as long as your not over 1ml daily you will be fine. I try to stick to about .8ml to leave an air gap and have them in a holder which keeps them the right direction. I refill every Saturday night
I’ve been thinking about getting a 50ml vial and putting what I can fit and then using a vial spike and 1ml luer lock syringes I feel like that would be the most safe approach
But how would you know if everything is mixed altogether correct? Ie; different ratios of compounds each pull of the vial?
I’ve mixed compounds in vials because the blend/ratio I wanted wasn’t being made. I just gently agitated the vial for a little bit before pulling into the syringe.
If the ratios were different shot to shot it wasn’t enough for me to notice anything was off.
It was a blend of TNE, Dbol, and Adrol I was taking as a pre workout so if anything was off my levels were still stable as far as test goes. It was just a cherry-on-top to the cycle.
Every dose felt the same and it seemed that the oils blended together well but I don’t really have any way of measuring it to know for sure.
When I draw tren into a syringe with test, there is a clear and obvious color difference between the clear test and the dark yellow tren.
If I draw a bubble into the syringe and rotate it so the bubble mixes them together they become one shade of a lighter yellow. I take it in the morning and there is no color separation. It’s still one homogenous light yellow color.
That would lead me to believe that the compounds are mixing well and staying mixed. I might have to mix a dark compound like tren with a clear compound like test, swirl/agitate to mix them, and then let it sit for a while and see if they separate.
That’s why I haven’t done it lol I feel more comfortable with doing just a weeks worth because then I know I’m getting that weeks worth in at some point
Got it. I've considered the same thing as you. Would make things a lot easier. But then I'd just be wondering... Stressing
Yea especially for me with my primo I wanna make sure my e2 is in check could cause swings I don’t wanna deal with
Make sure you keep the rubber on the syringe plunger out of the oil or it will degrade into the oil. I did this last year and used 1ml syringes. I put sterile luer lock caps on the syringes and back filled, and then just pushed the plunger in and left it like 1/4" away from the oil. Obviously keeping the syringes vertical.
It does save a lot of time.
Yeah I did this. I did a bit of research before even starting this. That would piss me off to see rubber stopper floating in my oil!
I setup weeks worth of daily pins every Sunday I mix all my oils 4 compounds into one sterile vial and mix it well then draw out my daily 65units well worth it and haven’t had an issue yet. They say the plungers won’t degrade on a week I’ve read the rubber will be fine over 2 weeks so I’m happy just doing weekly
Same here. Never had a problem.
I thought about doing this, but part of me I think the OCD side feels like I wouldn't be getting the exact amount of each compound needed and it would be more parts Tren then Test or vice versa lol
I get that but also I went from pinning 3 times a week to daily so regardless the numbers will be right it’s when mixing long and short esters that it could be concerning but I feel like pinning everyday it all comes out in the wash
I do this all the time and agree it’s much easier / faster just to knock them out at the beginning of the week and have them ready to go each morning. I’ve been doing this for years and have never had an issue.
Okay cool good to hear you never got an infection or anything. I really do think its the way to go with daily pins, especially if you have a busy life. My only worry was infection.
