help with Bergger BPFP18 for albumen negatives

[LNV2011]

Hello,
I've just bought 10 meter of the Bergger BPFB 18 in order to enlarge copies of negative for albumen print.
I'm trying to make very contrasty negative, i've tried already several formulas of developpers like the Agfa 22 suposly to be contrasty, but the result are still too flat for me.
I don't want to buy developers as i had already lost lot of time getting use to some commercial product that have suddenly desapear, i need formulas.
I know i have to do a lot of testing, what i'm doing so far, but i'm getting lost, until now the enlarged neg i obtein are more flat that my original...
i know this film is not a contrasty one, but there must be a way to make it blow up !
Does anyone doing alternative process is using the same film with excellent result ?
Thanks a lot to share your experience

I have used paper developers, like Dektol, full strength to achieve strong contrast. I have no experience with that film. But here is a classic strong contrast developer formula. Use straight for most contrast.

Kodak D-19
Water 750 ml
Metol 2.0 g
Sodium sulfite 90.0 g
Hydroquinone 8.0 g
Sodium carbonate
monohydrate 52.5 g
potasium bromide 5.0 g
water to make 1.0 Liter

Use it full strength. Try 6 min, 68º as a starting point. To reduce contrast, try at 1:1 with more exposure.

There's no need to ask the same question in different forums. They're all frequented by the same people. Just pick one and stick with it.
