Some questions before starting (Tren Ace)

[fat tony]

OK guys, I have a few questions I need help with before starting out.

For 25 grams Tren Ace at 100 mg/ml I will need the following:

168.75 ml's GSO
12.5 ml's BA
50 ml's BB

Correct?


I was also wondering if someone can recommend me the best syringe filter of the following:

Whatman Membran Puradisc 25 PP0,45 µm
Whatman Membran Puradisc 25 AS0,45 µm

I don't really know the difference between them.


This is my first time homebrewing so please be kind

I promise to upload some nice pics when I get it all done


Thankful for replays!
