GHK-Cu gets a lot of skincare buzz but the systemic use cases are less discussed. In the literature it shows up for wound healing, anti-fibrotic effects, hair regrowth, possibly inflammation modulation.

Anyone using GHK-Cu systemically (Sub-Q or IM) for: chronic inflammation, injury recovery, hair, or anti-aging? What doses and outcomes?

I'm considering adding 2mg 3x weekly Sub-Q to a recovery stack but the signal-to-noise on 'it works' is low on forums elsewhere.

I've used GHK-Cu locally for scar remodeling (post-surgical) with good results. Systemic I've tried once, no notable effect at 2mg 3x. Could have been too low a dose, I don't know.

GHK-Cu systemic is niche for good reason — most of the impressive effects are local/dermal. Systemic dose-response is poorly characterized. 2mg 3x weekly Sub-Q is a reasonable experimental dose but don't expect BPC-tier results.

Topical GHK-Cu on my achilles insertion (cream formulation) seemed to help more than systemic anything. Local delivery is where this compound shines.

Peri-lesional GHK-Cu injection during a rotator cuff rehab felt different — the tissue around the lesion seemed to 'settle' faster. Hard to quantify. For systemic anti-inflammatory goals I'd stick with BPC.

The systemic GHK-Cu data in humans is mostly from topical pharmacokinetic studies and in vitro work. Claims of 'systemic anti-aging effects' are extrapolations. Healthy skepticism warranted.

Fair. Gonna scale my experiment to topical peri-injury use only. Not going to chase systemic.

Has anyone used it for hair? I've seen the Pickart research cited for that.

@curious_catL topical for hair is a defensible use. Systemic for hair is not well-supported. Topical scalp applications with a quality carrier are where the hair use case lives.

Net: GHK-Cu is a local/topical tool. Systemic use case is weak. Good thread for keeping expectations calibrated.

Learning a lot from these 'calibrate your expectations' threads. Thanks all.
