Got a recipe you follow or a link? I've seen the ones here too. I've been using 600ml a day for a minute, but my source is empty with literally everything else I'd want and don't really feel like paying $75 for shipping for a kit of a $65 project
I'll do a quick write up for simple syringe filtering. easy for personal use batches.
you can make do with bulk supplements l carnitine.
get sterile WFI from biologix.
get benzyl alcohol from med lab supply
get from Amazon:
-cheap magnetic stirer/hotplate
-some beakers for whatever size batches you want to make (I wouldn't make less than like 100ml)
-ks tek sterile 30ml vials
-vial decapper
-33mm PES sterile syringe filters
-50-60ml syringes
-caulk gun
-4-6" IV extension tubes
for a 100ml batch of 600mg/ml
mix 60g of carnitine in a 100ml beaker with 40ml of WFI.
let it spin on the stirer (won't need much heat if any)
add 1.5ml benzyl alcohol
once it's dissolved and mostly clear, top off to 100ml with more WFI and let that mix for a few minutes.
to prep vials:
remove cap, and use decapper to remove crimp without removing stopper (only if you want to recap yourself, otherwise you can just remove cap.
insert 21-22g needle into stopper (for filling) and another needle (can be smaller gauge for venting) on the opposite side.
attach filter to fill needle, followed by IV extension (optional but makes it easier)
to fill vials:
draw up 30-33ml into your 50-60ml syringe followed by 10ml of air.
attach your syringe to the open end of your IV extension or open end of syringe filter if not using an extension.
inject through the line and filter into the vial.
a caulk gun helps.
once filled remove needles and crimp new cap if recapping.
