Update on the zinc: I have recently seen info on another big server from one of the expert/mods that zinc supplements won't bind to the copper so they are essentially useless to take in conjunction with the Glow Protocol, but that the zinc isn't needed because you won't get copper toxicity from.the protocol. Have also seen that people are doing the protocol repeatedly without taking zinc and their blood tests showed zinc and copper levels were just fine. One user takes zinc and his daily glow protocol is 5mg daily of GHK-cu plus the other peps, and he's been doing it for quite a long time (a couple of years I think I recall) and is fine at that high mg of the GHK-cu, though watching out in case his nails gain a blue tinge, which has not happened. I'm glowing and taking zinc and started with 10 mg of zinc in advance and increased it to 30mg when I started the protocol, and just started taking 50mg per the protocol, and maybe it's the zinc or maybe it's the protocol - though only 10 days in - or maybe it's the IGK hair product I started using out of fear - but my hair, which hasn't fallen out at all since starting tirz, did seem to be dropping off my head at a rate that I noticed and then was scared by, and then I started the zinc and the protocol and the hair product, and my hair is staying rooted again. Sadly, I have no way to determine what is making the difference. Research is rarely straight forward.
