59 days Thought there was a subtle change after a week, no real results now that I gave this more time.
Return policy states only 1 empty bottle can be returned, that's 30 days supply out of the "60 day return" and customer will not be refunded shipping costs in either direction.
I'd highly suggest keeping your money.
Each follow up email after purchase points to concepts to pursue a healthy lifestyle & continue taking provasil.
I'm already doing most of this and if you do too you don't need this supplement as it won't add any improvement.
