I would seriously advise avoiding taking ANY research chem with a potential side effect THAT SERIOUS dude, just my opinion. The heart, yeah, that’s kind of a big deal.
Now minoxidil is safe, FDA approved, and the only real side effect is that your hair will look kinda greasy….BUT, you will have hair and that’s the main thing. And now that you can buy just generic minoxidil, it’s cheaper too. Used to be it was only sold as Rogaine, the brand name, and was much more $$$. Kinda like buying Ibuprofen vs. buying Advil, the brand name naturally is more expensive. Good luck.
