Good morning LongeCity and KJX!
Take it from me, I have tried every green shake out there and bought straight nettle from "lost empire herbs" but it won't reverse your hair loss. Get on the VMG (combine it with earth) and you will save your hair. I am 39, started balding when I was 21 and "I've tried everything in the book". You can stay on propecia for the rest of your life (like I was going to do) or you can fix your hair loss in about 5-6 months and save yourself thousands in shampoos, pills, surgery etc.
As it turns out (at least in my case), I needed more then just the nettle. I needed LOTS of nettle (leaf and root), lots of seaweed and some horsetail to save my hair. I have two bald grandfathers and I myself was starting to "rapidly" lose my hair around 23-24. I was on propecia at the time, on a synthetic multi. . . and I was in panic mode. I tried going for laser treatments 3 times a week (waste of money), I ended up losing some of my hair in the front (once its gone, its gone) and had to have a hair transplant surgery in the front but I was STILL losing my hair in the front and in the crown. I didn't stand a chance. . . until I started taking VMG (and later combined it with EARTH).
My opinion is subjective and I don't sell either product. I am simply a 39 year old guy who has been through EVERYTHING someone losing their hair could possibly go through.. . its horrible. You want to save your hair, get on VMG (teaspoon in the morning and at night) and same thing with the Earth and you will save your hair and your self worth (ego, pride. . whatever you want to call it). You will see as I did that you won't even need the propecia after about a year (propecia's benefits fade with time anyways and I was on it for a good 10 years before I realized that it was no longer doing anything for me). In full disclosure I have been off of propecia for 3 years already with no loss of hair.
All the best!
