GHK-Cu for pain and anxiety?

Question

I found this paper on PubMed about the regenerative actions of GHK-Cu. It goes over how the peptide affects cellular pathways and mentions that it might be possible to reduce pain and anxiety through skin absorption. I reckon the skin absorption part sounds a bit optimistic. I have used GHK-Cu before and it felt spot on for skin texture, but I never noticed anything affecting my mood or systemic pain. It feels like a stretch to say a topical can do that much. Most of the real recovery benefits I have seen from copper peptides seem to be purely local. Do any of you actually feel a systemic effect when using this, or is it just a placebo thing? I am curious if people who use higher research doses via injection notice a difference in their general wellbeing compared to the creams.

I’ve been doing a 1 % cream too, mainly for the skin. My HRV, sleep log and pain diaries stayed flat when I added it. I think the peptide stays in the dermis – the numbers don’t show deeper uptake. Have any of you actually measured blood before/after topicals? 🥗👀

I’ve been in the same spot – sub‑cut with GHK‑Cu on a low dose a few times a week and no big shift in HRV or mood. I did bump the amount to 250 µg twice a week for a Elf‑week and still nothing obvious; the numbers just edged a hair higher on a calm day. Maybe it’s just my own body or the fact that it’s a short‑acting peptide – I’d love to hear if anyone’s seen a measurable change at higher, research‑grade doses or with a different injection site.

1 % GHK‑Cu cream in my routine, mainly for fine lines. My HRV and sleep scores didn’t shift when I started it, and I didn’t feel any change in my daily ache or mood. Skin absorption of copper peptides is usually quite local – the peptides are big and don’t cross the epidermis in measurable amounts. Iintään haven’t tried injections, so I can’t say if higher doses alter wellbeing. Anyone else notice any systemic lift, or is it still mainly a placebo?

I’ve used similar doses topically before and saw zero mood or pain shifts, just skin texture. Curious if anyone’s tried higher doses via injection and noticed a difference in energy or anxiety. Would love to know if the method matters more than the dose.

I’ve used GHK‑Cu serum for a few months and my skin felt smoother, but I didn’t notice any shift in my general aches or anxiety levels. Curious about a possible systemic effect I tried a very low subcutaneous dose around 100 µg twice a week for two weeks, tracking my HRV and mood scores. For me the numbers stayed flat – any change felt like it could just be placebo or normal day‑to‑day variation. I’d be interested to hear if anyone using higher research‑grade injections has seen something clearer in their bloodwork or wearable data.

Thanks for the detail. I’ve only used the topical, so 100 µg twice a week is pretty low. Do you have any bloodwork or longer‑term HRV data beyond those two weeks? I’d like to compare a higher research‑grade dose, say RW 1 mg once a week, against your baseline. Any markers you tracked would be key for thatovane.

lifter_cole · Answer

I’ve done the same 1 % cream, no change in HRV or pain logs either. I haven’t taken blood samples, so I can’t confirm skin‑only absorption. How would you go about measuring copper or GHK levels in the bloodstream after a topical? Thinking of a cheek‑pad or plasma test next.

lifter_cole · Answer

Thanks for the detail on the 250 µg dose. I only used the cream, but that was at about 1 mg per drop. The sub‑cut site you mentioned – did you use the abdomen or arms? 5 mg and saw a slight lift in energy a day or two after. Have you seen any difference in time‑to‑effect if you hold the dose longer?
