I was just thinking, because usually what i do about things i'm interested in is overthink about it, if it could be possibile that if you are having more systemical side-effects it's because you are having difficult to transform the minoxidil in his active form which is the one who is responsible about make your beard grows. (this is mentioned in this video https://www.youtube.com/watch?v=9AglocxoOK4)

So, if you are not "metabolazing it" (not sure if the term is correct, i'm not a doctor) the worst will be your systemic side-effects.

I'm just basing my theories on a few youtuber and progress pics here on the subreddit, but i noticed that people who are 100% sure it works for them when asked about side-effects they rarely mention something big.

For me it's to soon to speak, after this thread i opened a few days ago: https://www.reddit.com/r/Minoxbeards/comments/8xn1o3/some_reassurance/

i decided to give it a try and today is my first day, two applications 1ml foam and i had absolutely zero side effects, i keep checked my blood pressure and heart beat and it was exactly as before. At least i can say i'm not allergic to it, probably.

Those are just some theories i would like to discuss with you guys, i have absolutely no proof nor i am a specialist.
