What to Expect
Week 1 – 2
Early changes are subtle. Some people notice skin looking more hydrated and refreshed as GHK-Cu begins supporting the skin's repair processes.
Week 3 – 6
Skin texture and firmness often improve as collagen and elastin support builds. Tone tends to look more even and the complexion more rested.
Week 8+
Continued support for skin quality, tissue repair, and healthy aging. Benefits accumulate with consistent use as part of an ongoing protocol.

GHK-Cu Injection Pen
GHK-Cu is a naturally occurring copper peptide studied for its role in skin quality and tissue repair, delivered by subcutaneous injection for direct absorption.
Ideal for adults looking to support skin quality, tissue repair, and healthy aging. It is not intended for anyone under 18, or for those who are pregnant or nursing. If you have a medical condition or take prescription medication, talk with your provider before starting.
Yes. This formula contains no toxic fillers, preservatives, or parabens. Each batch is prepared in a licensed compounding pharmacy for purity, potency, and consistent results.
Topical copper peptide creams are limited by how much can pass through the skin barrier. A subcutaneous injection delivers GHK-Cu into circulation directly, so it reaches the tissue rather than sitting on the surface.
Week 1: inject 0.1mL (dial to 10) subcutaneously, 5 days on, 2 days off. Week 2 and beyond: increase to 0.15mL (dial to 15) and maintain the same 5 days on, 2 days off schedule. Insert at a slight angle and hold for 5 seconds after pressing the button. Inject into the abdomen, upper thigh, or glutes, and rotate sites weekly to avoid irritation.
Most people tolerate this well. Mild, short-lived effects may include temporary redness, tenderness, or irritation at the injection site. Rotate sites to minimize local irritation, and contact your provider if you experience unusual or persistent symptoms.

What It Does
A naturally occurring copper peptide studied for its role in skin quality, collagen support, and tissue repair, delivered by simple at-home pen injection.
GHK-Cu is studied for its role in skin firmness, texture, and a smooth, healthy-looking appearance.
Research associates GHK-Cu with the body's natural collagen and elastin production, the proteins behind resilient skin.
A copper peptide studied for supporting the body's natural tissue repair and renewal processes.
Supports the skin against oxidative stress, one of the drivers of visible aging.
GHK-Cu levels decline with age. Supporting them is associated with skin and tissue quality over time.
Associated with a more even, refreshed, healthy-looking complexion as skin quality is supported.

The Science
A simple subcutaneous pen delivers GHK-Cu into circulation, so the copper peptide reaches the tissue rather than sitting on the surface of the skin.
A quick pen injection places GHK-Cu into the tissue just under the skin, where it begins absorbing into circulation.
Unlike a topical cream, which is limited by how much can pass through the skin barrier, injection delivers the peptide into the bloodstream directly.
GHK-Cu is a copper binding peptide studied for signaling the body's natural repair processes, including collagen and elastin production.
Skin and tissue changes build gradually. With consistent use over 4 to 8 weeks, many people notice improvements in skin quality, firmness, and overall appearance.
Why Lavi MD
Most peptide suppliers prioritize volume over patients. We were built differently — by a physician, for patients.

"Every product we offer is something I would prescribe to my own patients. Our formulations are designed for clinical outcomes — not marketing claims."
How We Operate
Built by a Physician, Not a Marketing Team
Lavi MD was founded under physician supervision. Every formulation, every dose, every protocol is reviewed by Dr. Moulavi before it reaches a patient — not outsourced to a contract manufacturer with no clinical input.
We Limit Shipping Days to Protect Your Product
We only ship Monday and Tuesday. That's a deliberate decision — it ensures your order arrives before the weekend and never sits in a carrier facility over two days without refrigeration. Most brands don't think that far ahead.
We Treat You Like a Patient, Not an Order Number
Our team includes clinical staff who understand what you're taking and why. If something goes wrong with your order — a warm shipment, a missing component, a question about your protocol — we fix it. No automated runaround.
We hold ourselves to the standards set by the bodies advancing peptide science, so you can have full confidence in every product you receive.

My esthetician asked what I had done. I had not done anything except start this. Six weeks in and the texture around my jaw and neck is visibly different.
