How it works
AHK-Cu mimics naturally occurring peptides and copper ions, signaling the body to promote collagen and elastin synthesis. It also appears to stimulate fibroblast activity and reduce inflammation, contributing to improved skin appearance and hair follicle function.
Who should take it
Adults looking to address dull skin, hair thinning, premature ageing. Particularly relevant for people who prefer a targeted single ingredient and who have ruled out an underlying condition that needs medical care first.
Avoid / careful
Pregnant or nursing women without clinician oversight. People on prescription medication affecting the same pathway should consult a doctor before combining. Side effects are uncommon at recommended doses but mild GI upset can occur when starting.

FAQs
Frequently asked
How long does it take to see results from AHK-Cu?
Visible skin changes are often observed within 8-12 weeks of consistent daily dosing.
Can AHK-Cu be combined with other supplements?
Yes, AHK-Cu can be layered into a broader protocol. However, consult a clinician if you are on prescription medications affecting similar pathways.
What is the difference between AHK-Cu and topical copper peptides?
AHK-Cu is taken orally as a supplement, working systemically, whereas topical copper peptides are applied to the skin's surface.

About AHK-Cu (Copper Peptide)
AHK-Cu (Copper Peptide) is a peptide supplement used to support skin, hair and connective-tissue health. Copper tripeptide researched for hair growth. It is available in capsule form and dosed for adults in India and internationally. As a peptide-tradition entry in the SacredBod catalog, it is positioned as a single-ingredient option that can be used on its own or layered into a broader protocol. AHK-Cu (Copper Peptide) works through the mechanisms characteristic of its class — see the mechanism and research sections for detail. It primarily acts on the skin, hair, connective tissue, and effects are dose-dependent, typically becoming measurable within 8-12 weeks for visible skin changes. Consistency matters more than dose size for this category.
Evidence
AHK-Cu (Copper Peptide) carries an evidence grade of C in the SacredBod catalog, reflecting emerging human evidence for skin, hair and connective-tissue health. Copper tripeptide researched for hair growth. Benefits are cumulative rather than immediate, typically becoming noticeable within 8-12 weeks for visible skin changes, and individual response varies.
Dosing
A typical dose is 5 mg, taken with food, usually in the morning. Start at the lower end, assess tolerance, and stay consistent; more is not automatically better.
Cautions
Pregnant or nursing women without clinician oversight. People on prescription medication affecting the same pathway should consult a doctor before combining. Side effects are uncommon at recommended doses but mild GI upset can occur when starting.
