I have not but was doing some reading on it and it may be helpful. Only reason I didn’t buy some was because it mentions weight gain, which isn’t great for me.
I tried it back 20 years ago on the avice of my MDA neuro and I do not remember why I stopped.
My cousin took classes on health and fitness. She told me she’s been reading up on creatine . She feels I would benefit from it . To try and help save what muscle I have . I’ll have to look into it further though. Because I was reading the other comment… I’m not looking to add extra weight.
