Well it depends I guess what you’re trying to get out of it. Pre-work out, you’ll burn it as fuel. I would think you would want to reserve it for an HIIT session or race of some sort since it’s short on calories. As a post workout supplement, I guess you’d be going after signaling effects. BHB can do a lot to tamp down on inflammation, for example. Might be helpful for weeks 3 and 7 of build plan, or a multiday stage race where you have to go hard day after day.
