Can goji berries have any anabolic effect?
Not any more than blueberries or any other berry. They’re for sure really good for you, but not that special. If they’re affordable, go for it, but don’t expect anything magical.
Think about it this way; bodybuilders have been getting absolutely yoked for decades, without goji berries. And without ashwaganda, or reishi mushrooms, or whatever else is trendy.
