ghk-cu burning Why this audio? Because injecting feels like a constant wasp sting so it takes me about 15 seconds to pin .2 mL. I dread this shot every night for that reason Why Does Ghk Cu Burn

A: Injectable GHK-Cu typically provides higher bioavailability and deeper tissue penetration compared to topical applications, often resulting in more dramatic results for significant skin concerns or hair loss

A study by Pickart et al

Choosing your injection site Subcutaneous injection means delivering the peptide into the fatty layer just beneath your skin

Direct application of ointment is the most commonly used form of administration at present, but only a few drugs can effectively penetrate into the dermal layer with therapeutic concentrations through this route [29]

The "right" dose sits in a narrow window that depends on: Delivery method - injectable GHK-Cu vs topical GHK-Cu vs oral/sublingual GHK-Cu Goal - skin rejuvenation , hair and scalp support, wound healing , general anti-ageing Individual factors - age , skin type , baseline GHK levels , other peptides being stacked Natural plasma GHK falls from roughly 200 ng/ml at age 20 to around 80 ng/ml by age 60
