GHK-Cu peptide cream

Once a day. Five pumps (about a gram) onto clean, dry skin — face and neck. Most patients apply it in the morning or at night based on their routine. Your provider will help you pick the timing that works with anything else you’re using.

Yes. GHK-Cu cream at iThriveMD is a prescription formulation compounded in our sterile cleanroom. It’s not something you can grab off a shelf — a quick consultation with one of our providers is the first step.

Over-the-counter copper peptide products are typically cosmetic-grade, much lower in concentration, and mass-produced to have a shelf life of about a year. In contrast, our cream is a 2% prescription formulation that is freshly compounded in our own USP 797-certified sterile cleanroom. We source our raw peptide from FDA-reviewed, DMF-listed manufacturers, and every batch undergoes testing by two independent third-party laboratories—Eagle Analytical and ARL Labs—to ensure purity, potency, and the absence of contaminants. You can request the Certificate of Analysis for the specific batch you are using at any time.

In our lab, located on-site and not overseas or shipped from a warehouse, iThriveMD operates as an in-house physician compounding lab rather than a traditional pharmacy or supplement brand. Each bottle is freshly compounded in our USP 797-certified sterile cleanroom and is prescribed by your medical provider.

Patients typically begin to notice changes in skin texture and hydration within the first few weeks. Improvements in firmness and tone usually become visible between 4 and 8 weeks. However, significant structural changes—lasting ones—result from consistent use over 3 months or more, as this is the time it takes for collagen to rebuild effectively.

Yes, the order in which products are applied is important. Retinoids can increase skin sensitivity, and vitamin C is acidic enough to compromise the stability of copper peptides if used together. A common recommendation is to apply GHK-Cu in the morning and your retinoid at night, or to alternate them. It’s best to have your skincare provider review your complete routine to determine what works best for your skin.

Absolutely. Sunscreen is the non-negotiable partner to GHK-Cu. UV is one of the main things breaking down collagen in the first place — so wearing broad-spectrum SPF 30+ every morning protects the work your cream is doing at night.

It depends on what you’re after. The cream is best for targeted facial support — firmness, texture, tone, and recovery after procedures. The injectable works systemically to achieve broader goals such as hair growth, wound healing, and whole-body regeneration. Some patients use one, some use both together. The cream is applied once a day; the injectable is given 5 days a week on a 3-month-on, 1-month-off cycle and requires a daily zinc supplement. Your provider will help you pick the right approach based on your goals and monitor how your skin responds over time.

Most patients have none beyond mild tingling, slight redness, or a little dryness in the first week, and that usually settles as your skin adjusts. Less common reactions include contact dermatitis (a rash or itching that doesn’t resolve), persistent redness, or a localized copper reaction. If you notice any of those, pause and call your provider.

This product may not be suitable for everyone. Please skip it or consult your healthcare provider first if you:

• Have a copper metabolism disorder (such as Wilson’s disease or copper toxicity) or severe liver disease that affects copper processing.
• Have active skin cancer or a suspicious lesion in the area where you would apply the cream.
• Know that you are sensitive to peptide ingredients or copper.
• Are pregnant or breastfeeding (as safety has not been established).
• Have an active flare-up of eczema, a wound with broken skin, or an active infection in the area of application.
• Your healthcare provider will review your complete medical history before prescribing. This is the purpose of the consultation.

We don’t prescribe GHK-Cu cream during pregnancy or breastfeeding — safety in those windows hasn’t been studied. If you’re using it and find out you’re pregnant, stop applying and let your provider know.

Keep it at room temperature, away from sunlight and heat. No need to refrigerate. The pump bottle keeps air out — just cap it after each use.

Stop using it and call us. Most reactions calm down within a few days of pausing. Your provider can help you figure out whether to try it again at a lower frequency, pair it with something soothing, or switch approaches entirely — no pressure to stick with something that isn’t working for you.
