Same filter 2 compounds/oils

[Brucie]

First attempt at filtering finished coming up, I'll be filtering around 90ml test e in gso.

I've also got 30ml deca and 10ml test e both in mct. I've got separate vials for each but my question is can I use the same filter?

If its okay then I should do the 90ml test first then the deca? Or is another filter required in this case?

Yes you can use the same one if you don't contaminate it, the carryover will be minimal and will be further diluted.

Is that a syringe filter?
If so, you can discard the first few ml that come out of the filter after adding the second one
otherwise it will contain a mixture (of unknown composition) of both steroids.

You may even separate the filter from the syringe just for a second while you pull a few cc’s of air into the syringe. Put the filter back on and you should be able to push most of the remaining oil of product one out. It may have a lot of bubbles, but the will dissipate.

Then remove the filter and add product two.

So I filtered the 90ml test e, after about 50ml the flow rate was significantly slower. The final 40ml took about twice as long as the first 50, this was through a .2 whatman syringe filter, 20ml syringe, 18g pin with a 25g breather pin.

I am aware from reading that when filtering homebrew that the filter will flow slower and slower as the filter accumulates particulate, but is this normal when filtering finished oils? Does the reduced flow rate of finished oil over time indicate poor filtration of the original finished product or is this a normal thing?
