Ahk-Cu is generally not meant to be injected. AHK-Cu is like a skilled craftsman who does their best work on-site (topically). Injecting it is sending them into a job they weren’t trained or studied for. I have been researching ahk-cu topically for about 6 months now and have had very good success and growth with it. I mix 1 gram into a 2oz bottle of HA and apply to my scalp every other day.

@Marcie T I've never put mine in the fridge. I keep it in my bathroom cabinet and it's been perfectly fine. Takes me about 2-3 months to go through a 2oz bottle. I would never use it if I had to go back and forth to the kitchen.
