So I signed up just to post this reply -
I did Prop for a year and switched over to pelo-1 from 4rx and nothing alarming happened. My MPB scalp itch resided a little (good) and I'm keeping close watch for any changes.
I save about $60 a month.
From my research I gather that it's practically the same price to produce 1mg fin pills as it is to distribute sugar pills/placebo etc. so the company has nothing to gain only customers to lose by selling fake product.
I'm less worried about fakes than I am about the product containing some other hormone type substance that causes other problems so I'm also watching for side affects.
Don't expect any results in under 3 months. Remember, the hairs that shed today went into telogen state at least 3 weeks ago so the soonest you'll see improvement is three weeks.
