This bloodpyre poison states that it gives str bonus along with the damage it causes. However there is no duration given. Does the str bonus last while you have ability score damage? Is it permanent? Or is there some other duration that I just have not seen or found?
Here are a few other poisons that I looked at in reference before asking here.
Nerveblast - Has listed duration for its secondary effect.
Blue Star - Persists 1 week after it runs out.
Sword Witch Hunters - uses the wording "As long as the poison persists"
Crone's Curse - uses the wording "During this time"
Rage Spittle - Lists no explicit duration from its secondary effect
With these examples, I can see an argument for the bonus only lasting the frequency, and I can see it lasting longer. I have nothing in the d20 poison section that states their effects end when the poison runs its course, and nothing in this paizo FAQ section about poison that states similar. Please note I am looking for an official ruling. If one doesn't exist that is an acceptable answer.
