I have been using the MT for about 3 years. It really helped improve my hair and growth. The eBay member who sent me the MT gave me great email support. It was really interesting. They asked about my age, diet, etc. We did about 10 email's and I decided then to try their other products. They have a really good system called Rouse Hair Growth. I have been using it now for about 6 months and it is pretty amazing. I had been losing hair from straightening irons, heat, and too much stress. I tried their Rouse and it supplemented my nutitional needs I guess, because my hair has become so incredibly healthy now. Also, I feel better overall.
Good luck with your hair also...I hope this helps anyone out there who needs help. Oh, BTW, when talking with guaranteed-hair-growth they send out a flyer from Eqyss which shows the MT used to be made for humans and called Rejuvenator, the company stopped making it as the ingredients are the exact same as the Horse Rebuilder. SAME PRODUCTS. The MT is perfectly safe for human use, so give it a try.

Oh, I saved the link of where I find them when I need to re-order:
