Thanks @Lieselotte for your updates! I just finished up a vial of Epithalon. I was taking between .3 and .5 per day. A few things I noticed. Living in the desert and being over 40 my skin is normally very dry and that has gotten so much better! I also can attest to not having as severe crashes. I just returned from a VERY active and hectic family trip. I was tired but not like I would normally be. I was hoping for better results in the deep sleep department as others have mentioned but that hasn't been my case. On the upside, I don't wake up AS tired and I have more energy first thing than I used to. I also think that it's regulating my hormones a bit. I am staying on this one for sure to see where it goes. I have not had any negative side effects and I am quick to everything.
