Has anyone here tried both GHK-Cu and AHK-Cu for hair?

I’ve been going down a bit of a rabbit hole on copper peptides and I’m trying to understand the differences between these two.

From what I’ve gathered:
- GHK-Cu seems to be more general (skin, healing, maybe hair support?)
- AHK-Cu looks like it’s more targeted toward hair follicles and is usually used topically

For those who’ve actually experimented with either (or both):
- Did you notice a difference in hair thickness, shedding, or regrowth?
- How long did it take to see anything?
- Did you run them solo or stack with anything else?

Not looking for medical advice—just curious about real-world experiences and what people prefer between the two.

Appreciate any insight 🙏
