an honest timeline
Results from peptide therapies take time. Here is what our patients actually experience:
Weeks 1 to 2:
Texture improvements and reduced dullness. Skin feels denser and more hydrated within the first few weeks as collagen synthesis activates.
Weeks 4 to 8:
Visible firmness and fine line softening become noticeable. Patients on the oral protocol begin to notice hair quality changes such as strength, shine, and reduced shedding.
Weeks 8 to 12:
Full clinical results window per published research. Peak collagen support, measurable skin firmness, and steady hair follicle activity. The milestone most patients use to evaluate the protocol.
Month 4+:
Maintenance phase. Most patients continue indefinitely. Your body produces less GHK-Cu every year, so consistent use maintains the rebuilding.

FAQs
What is GHK-Cu and what does it do?
GHK-Cu is a naturally occurring copper-binding peptide your body produces. It signals skin and tissue cells to repair, regenerate, and behave younger. It has been studied in dermatology and longevity research for over 40 years for its role in collagen production, skin firmness, hair density, and tissue repair. Production drops sharply with age, which is the case for supplementing it through prescription-grade topical and oral formats.
How is the prescription different from what I can buy over the counter?
Three things make the prescription version meaningfully different. First, pharmaceutical-grade purity. Compounded prescriptions are prepared under USP 795 standards rather than cosmetic regulations. Second, provider review. A licensed Fitish provider screens every intake for contraindications like Wilson's disease, copper sensitivity, pregnancy, and breastfeeding before any prescription is issued. Third, the systemic oral form. No over-the-counter copper peptide product offers GHK-Cu in a daily sublingual tablet that supports your body from the inside out.
How long until I see results?
GHK-Cu is a cumulative peptide, not a quick fix. Most patients see initial smoothness in 1 to 2 weeks, visible firmness in 4 to 8 weeks, and full clinical results in 8 to 12 weeks. Studies show a 22% improvement in skin firmness and a 29% increase in skin thickness over 12 weeks of consistent topical use. Stick with the protocol. Individual results vary.
Can I take both the oral and the cream together?
Yes, and most of our patients do. The oral sublingual tablet supports your body systemically, contributing to collagen, hair density, and recovery from the inside. The compounded cream targets the skin directly for firmness and smoothness. Stacking them is the inside-out plus outside-in approach. Many patients start with one and add the other once they see how their skin responds.
Is GHK-Cu safe? Any side effects?
For most healthy adults, GHK-Cu has a strong published safety profile across more than 40 years of research. The most common side effects, when they occur, are mild: redness, tingling, or temporary dryness with the cream, and a metallic taste or oral tingling with the tablet. GHK-Cu is not safe for patients with Wilson's disease, other copper metabolism disorders, during pregnancy or breastfeeding, or for anyone with a known copper or peptide allergy. A licensed Fitish provider reviews every intake before any prescription is issued and screens for these contraindications.
