I take it. I also take testosterone which in my opinion is far superior for strength. Do I notice any potassium channel blocked myelin improvements? For sensory- absolutely not, still going numb weekly. Motor function? I have to admit I do a heck of alot more since I started Amp. I also push myself every day (sore right now) all I got & eat at least 100 grams of protein.

I read someone was worse when they stopped taking it then before so factor that in as well. I'll keep taking it & pushing myself. No side effects here.

For strength look into testosterone ($100 for 4 months worth, 12+ months worth for woman), raising red blood count, b12 for energy. Get them all to upper limit of range.
