Choosing a filter? Help on recipe?

**cakeman2** · 03-21-2019, 11:10 PM

OK which filter would be best suited to withstand high EO or Guiacol just high concentration of solvent?

I read that BA melts PES filters, nalgene filters will also fuck up when exposed to ethyl oleate. etc So can you guys help me on this subject? Choosing a filter best suited?

Would be using a recipe with:
Guiacol
EO
BB
BA

Solution will contain either all 4, or Either EO or G in higher concentration.

E.G

75mg/ml tren base

7.5 g tren base
24ml BB
25 ml EO
2ml BA
2ml G
40 ml MCT oil

Also is there a more mechanical approach to determining these numbers? (%v/v of solvent) Is there a method one can point me to other than trial and error?

Thanks to all
best regards,

Water based or oil based?

I'm looking for a good oil based recipe for both tren base and TNE

Shit will hurt at 100mg/ml regardless. This UG-lab in my country sold their stuff really cheap, people bought it like crazy. Now everyone is selling their test and tren base.

If you go to this link it shows all the different filter materials and their compatibility. By reviewing the chart and knowing I’m using Benzyl Benzoate and Benzyl Alcohol I can see the PTFE filter is best. No filter material is recommended for the Benzyl Alcohol so my personal plan is to add it after filtration to avoid any final product contamination via filter material degradation$, just my 2¢
