0.45 micron filters are GTG. It used to be the standard until it was discovered that Brevundimonas diminuta got through the filter. So the standard became 0.2-0.22 micron. Get PVDF-filter. Get a brakebleeder.

Injecting to much at once, injecting technique, jerking the needle etc.

Could you upload a better picture? No it's not ruined but you should add BB. If you got legit raws, your recipe or calculations are wrong.

PVDF .22 micron filter is a good choice. Just order or buy a regular brakebleeder, that's all you need. Bottle top setup will filter your gear faster than it takes for you to put on your jammies :) I haven't tried the autofil-filters myself, but I read that if your careful with the pressure the...

If you have a proper lab I suggest you get a pillpress instead. You'll be able to produce a lot more. Manual capsule press is time consuming. Even an experienced capper can't produce nearly as much as a pillpress. It all depends on you, how good quality products you want to make. You can use...

Those filters aren't made to filter oil. So you'll never be able to push 100ml of oil through those filters. Oil should NEVER be hot. I never go above 40 degrees Celsius. Yes you can rupture the membrane or crack the actual syringe filter if too much pressure is applied and/or the oil is hot...

I don't think that will work.

I read that oil will make aromasin get absorbed better, like 40% or something. So I had this great idea to try to make an oilbased aromasin solution. Aromasin is almost "flaky" so it was a really bad idea. Managed to dissolve some of it. But some just gathered on the bottom. I later read that...

Depending on what concentration you're making, PEG and 90-95% ethanol will dissolve most compounds. At least all the ones I've tried. Using oil is not recommended, I've tried it a couple of times.

PEG-300. It all depends, what concentration do you want to make?

I've been reading about choline since it's mentioned a lot on nootropic forums. All you need is eggs to get a decent dose of choline.

It's hard to get ephedrine. Canada is easy though, kaizen ephendrine but I haven't found any shop that willing to ship to the U.S or europe.

No. You wouldn't even be able to get that stuff through a pink needle.

Autofil brand is pretty good, people recommend them. But the filter membrane isn't compatible with BA and BB (it's a PES-filter) Try to find a 500ml bottle top filter with PVDF-filter instead. You can't change the filter since it's stuck there. You can only use these setups once. Get a sterile...
