Are pre-workouts really that dangerous? Keep seeing topic athletes having heart and liver issues, is that a main cause of concern?
Pre workouts might have too much caffeine. Also, they’re a supplement so they are not regulated. You never know what else might be in it, and whatever is listed on the label might not be what you’re getting. Only buy from third-party tested companies and also the ones with the NSF-certified for sport logo. At the same time, you can just make yourself a coffee and eat a banana and it will have the same effect.
Just have some coffee, my good man. Pre-workouts are basically caffeine and a bunch of barely efficacious ingredients. If you like the pump you get from them, purchase some L-citrulline or citrulline malate to complement your coffee.
Some have really high amounts of caffeine in em so just be wary. Usually go with the brands that have the certified for sports logo like mention in a comment above. The main ingredients I go with are creatine monohydrate, beta-alanine and L-citrulline. Those alone do more than enough for the job. If you wish to then you can get those ingredients separately and mix em with your favorite sports drink before a workout.
Also, avoid the ones that are labelled as ‘concentrated’. Utter junk. A good serving size is around 10g or more.
