Did a search on the amount apparently it is correct.
he mean proline incorporation per g protein and collagen ... Vaginal misoprostol. (800 g). N=112. Sublingual misoprostol. (800 g) ...
Can you provide a link? 800 grams of a prostaglandin all at once is going to be lethal. Also, if the typical (800 microgram) dose costs even just $50, we are talking about $50,000,000 of drug given to just one patient. For this alone reason I would find the claim incredible.
