I have been running GHK-Cu for three weeks and the honest summary is that the effect is smaller than the internet suggests and real.
Vivid dreams and mild headache for the first 10 days, then nothing. Textbook for this class, apparently.
The effect size I actually noticed is roughly a third of what the write-ups imply, and it took three weeks to be sure.
Vial content, sterility and reconstitution are three separate questions and the certificate answers about one of them.
Willing to accept that my own experience is the weakest evidence in the room.
What is the first thing you would read if you were starting from zero?
Baseline first. Currently on GHK-Cu myself.
Stupid question: how do you know whether what is in the vial matches the label at all?
Baseline first.
Narrow conclusion.
How long before you can reasonably say something is or is not doing anything?
A plausible mechanism is not an outcome, and this class is the textbook example.
Narrow conclusion, briefly right. Broad conclusion, interestingly wrong. I know which I keep choosing.
Is a baseline blood test really necessary before starting something like this?
Narrow conclusion, briefly right. Broad conclusion, interestingly wrong. I know which I keep choosing. How long have you been on GHK-Cu?
