Winny Options

Well guys, i dp plan on running winny in the future but my selection is rather limited. I'm not willing to shell out the extra cash for zambons, so it only leaves me a couple of options. Which would you pick for the highest quality out of these?

BD 50mg winny tabs (big yellow ones)
Denkall 100mg/ml (10ml vial)
Denkall 50mg/ml (20ml vial)
Quality Vet 100mg/ml (20ml)
Quality Vet 50mg/ml (20ml)

If price was the same for comparable amount of product and all were certifiably legit, which would you pick. Thanks guys for the help.
