Dude I have used creatine for about 2 years and protein powder for atleast 4 years just to find out it was a fuckin slop.
The supplement industry is the most shady industry out there. It’s totally unregulated. They have been openly caught using heavy metals like lead in their products. All the research you read online are fuckin funded. They just want you to believe that you need their products.
Your ancestors weren’t looking for optimum calories and shit. They just ate, slept and lifted heavy.
