Blood Booster and Sanguine Mutagen

[Aristophanes]

Any rules regarding elixers and mutagens interacting with each other?
For instance, Blood Booster[This elixir bolsters your body's natural defenses and ability to resist maladies that travel through or affect blood. For 10 minutes you receive the listed resistance to persistent bleed and persistent poison damage, and you lower the DC for any flat checks to end persistent bleed or persistent poison damage as if you received particularly appropriate aid.} counteracting The Sanguine Mutagens drawbacks[Whenever you take piercing or slashing damage, you take 1d6 persistent bleed damage].

[Errenor]

I don't see any reason for them to not work together. Blood Booster is not a mutagen (but is a very good item).

The only rules are the general ones, like "you can't use 2 polymorph effects" or "if you use a Morph effect you can't morph a part that's under Polymorph" and the likes.

Apart from that, you're free to spend resources to try to mitigate drawbacks like the combination you listed.
