Running several products from Ergo, and one of them is MT2. I needed a one week speed tan before going out of town, and I have to say that it delivered. Using a low power tanning bed (never even for a full 20 min) and starting at 500mcg, working up to 1mg, had me much darker in 7 days. Phil did send me a Matrixyl? as a freebie....from what I understand, it is primarily used for cosmetic/anti wrinkle purposes. Any noticeable benefit for younger guys like myself? Last resort would be to knock the wrinkles outta my balls, and see if my wife likes it j/k
