It's pure retardation. Many are getting side effects on 2.5%, and they should do because that's 25-50 times the needed dosage.
I've been using 0.1% from Murray Pharmacy (liquid solution which is much easier to apply) and it's going really well.
I genuinely have no idea why anyone is still ordering from Farmacia Paratti.
**A couple of comments. First agree with you what is the logic of a 2.5%? If some studies use 0.5% or even 0.25% why go to 2.5% which is 25mg per ml! Well, one reason is it works but the higher the concentration the more likelihood of sexual side effects unless there is a way to prevent systemic absorption and I think there is.
A giant step forward is the liposomal formulations that reduce percutaneous absorption by maybe 50%. In other words less FNA is absorbed thru the skin into the body. Now here is the good news..... by adding other components, gels, thickeners, sufactants-- absorption is reduced even more.
I do not have numbers but I will suggest there is very little, maybe not recordable when lower FNA concentrations, ie, 0.5% are used. There are studies that validate the liposomal question of absorption, we know that. Now, you can find that by creating a special type of film or gel there is barely a measurable about of a decrease in DHT levels.
Here is what I suggest, ask your Doctor for a DHT level and a prescription for Liposomal Finasteride at 0.5% and use daily 2-4ml depending on hair length or amount of hair present. Use with Minoxidl 5% to help wet the scalp. The trick is now to find a pharmacy that knows how to make a state of the art product I have mentioned. Farmacia Parati is redicously expensive and a 3 month wait when I sent them a rx.....so get the rx and from your Doctor, he may, like Ron Shapiro MD in Minneapolis, carry this advanced formulation and then get your refills mailed to you at....half the price of Farmacia Parati.....I don't understand why compounding pharmacies do not have the new formulation but I do after many hours of research.
If you cannot find a pharmacy, PM me and I can direct you. I don't think I am allowed to mention a compounding pharmacy.... This new formulation is better, IMHO, with minoxidil 5%, is the absolute best we have going for us.......and it works. I do not work for Shapiro or any physician but I have done the research....don't fret about your hair, I won't guarantee everyone will grows yards of hair but the studies claim great success, in thicker hair and new hair growth. Please do not question my research, try it first or do your own research.....they say it takes 10-12 weeks to see results but some begin to see changes in as little as a month. If it is not liposomal, forget it....oh, I doubt anyone will have side effects.**
Best to all.
