The Blackheart Effect!
No BS. Just Feedback.
Rogue gave me my fire back. Energy’s up, I’m sharper at work, bedroom, and in the gym. 10/10.

I sleep like a damn rock now. First week on Slumber and I’m not groggy anymore
— Jason R.
Didn’t think a stack would actually help, but this combo works. Better sleep, better mood, and I’m back in the gym 4x a week.
