. 22 Zap caps and another brand I can't remember .. I have used them both
500ml size and a hand pump... I have done them warm and cold both took no time at all.. From the glass to the vials takes me the most Time
And I normally cook TC.. I'd assume they would filter with similar times
I filter 400ml at a time with one 500ml bottle top filter in 15 mins with only pumping my hand pump up like 2-3 times.. What the hell kinda filtering u doing that takes that long?
It takes no skill to cook test e.. And it does take more time to filter it then make it.. Your guy sounds lazy or uneducated... And I used syringe filters once.. Just once and never again.. It's a shitty process even with a calk gun.
After the first time i just bought bottle top filter...
