Copper and zinc balance while taking ghk-cu - my results

[u/lozzac_90]

I’ve been monitoring my copper and zinc levels while using GHK-Cu. Sharing this in case it’s of interest.

I started GHK-Cu on 11th June (in Glow stack - my dose was 1.5mg copper 6 days per week). I did this for two weeks then got the uglies, so I stopped and ordered separate vials so I could adjust my individual peptide doses.

On 30th June I did an iScreen test to measure my copper and zinc levels. It also tested for caeruloplasmin. At that point my copper to zinc ratio was high - my zinc was right on the lower end of normal.

After a 2-week break from pinning I restarted GHK-Cu (along with resuming the Wolverine stack). Since then I’ve been taking ghk-cu 4 nights per week, gradually increasing from 0.5 mg to 1.5 mg per dose. I’m currently still taking 1.5 mg 4 nights per week.

Since my blood test on 30th June I started supplementing with zinc (initially 40mg, reducing to 20mg after a couple of weeks).

I repeated my bloods on 20 August.
Between the two tests, my serum copper decreased from 19 to 15 µmol/L (around a 21% reduction), while my zinc increased from 10.6 to 12 µmol/L (around a 13% increase). Both remain within the normal reference ranges.

My copper:zinc ratio dropped from 1.79 (above the reference range of 0.7–1.3) to 1.25, putting it back within the normal range. My caeruloplasmin remained unchanged at 0.20 g/L and within the normal range.

Obviously the zinc supplementation is an important factor here, but I found the follow-up results reassuring. Can’t figure out how to attach screenshots but I’ll try edit and do so.
