GHK-Cu has become increasingly popular in wellness and longevity circles for its potential to support healthy-looking skin and hair.
But most people discover it the same way: through friends, podcasts, social media, or online forums, followed by hours of research that often lead to more confusion than clarity.
You’ll find:
For something that involves a protocol and a real commitment, that “figure it out yourself” approach isn’t ideal.
Nuri was built for people who want a more structured, clinical path.

Outside of a structured program, people are often left to make important decisions without safeguards:
Many online ‘research use only’ products are labeled for laboratory research, not human-participant programs, and leave the consumer with limited clarity, limited support, and limited accountability.

Instead of piecing together a plan from fragmented online information, participants can join a structured at-home study program through a university-backed clinic.
This program is designed to provide:
Our goal is simple: create a structured research environment for exploring peptides responsibly, with more clarity, guidance, and support than the typical online peptide route.

All of the compounds in our peptide studies are meticulously vetted for purity, efficacy, and safety. We use a neutral third party lab to test all of our products on a routine basis and offer published results - for quality you can trust.

All purchases of Nuri programs are final. After your order is confirmed and medical intake filled out, we ship your entire 14 week program and are unable to reuse the peptides or kit after it has left our facility. Because of this, we are unfortunately unable to accept returns once it has been shipped.
Nuri’s Metabolic Health Program is a research program that uses Retatrutide experimentally under supervision. It is not an insurance-billed medical treatment, so we are not able to process insurance.
We do, however, offer flexible payment options — including interest-free monthly plans for eligible applicants — to keep participation more accessible.
Follow-up appointments are essential to monitor progress, make adjustments if necessary, and address any concerns or questions. An intake form must be filled out before shipment, and we request final feedback on your results.
Schedule a call at anytime during your program to discuss special needs. Be sure to consult with your own primary care provider before starting any new regimen.
Early studies suggest many people tolerate Retatrutide well. Most common are GI effects—nausea, indigestion/heartburn, stomach discomfort, diarrhea or constipation—especially during dose changes.
Less common: headache, dizziness, fatigue, dry mouth, mild injection-site irritation, small heart-rate increases; seek urgent care for severe belly pain, repeated vomiting/diarrhea, signs of gallbladder issues or pancreatitis, allergic reaction, or low blood sugar (especially with glucose-lowering meds).
The daily, natural supplements provided are specifically formulated to support the reduction and ease of these side effects.
Eligibility is determined based on your health history, current medications, and goals, along with safety criteria defined in our IRB-approved protocol. To see if you may qualify, you’ll start with a short online pre-qualification form (about 5 minutes). If you pass that screen, you can schedule a call with a licensed clinician to decide whether participation is appropriate.
This 14-week program aims to support appetite control, earlier fullness, and steadier energy so it’s easier to stick to a nutrition and movement plan. Many clients report smaller portions, fewer cravings, and clothes fitting differently; the pace and magnitude vary. Your clinician monitors tolerance and can adjust dosing, nutrition, and habits to support healthy weight-management and blood-sugar responses.
Timing varies by person and dose. Many clients notice earlier fullness and fewer cravings within the first few weeks as dosing ramps, while others need more time and nutrition tweaks to feel a clear difference.
If benefits feel minimal, discuss pacing and meal strategy with your clinician at your next check-in.
Within the Metabolic Health Program, Retatrutide is administered via subcutaneous injection as part of the investigational protocol.
Detailed administration guidance, safety instructions, and support from licensed clinicians are provided to participants. We also encourage you to discuss any injection-based protocol with your own healthcare provider.
Retatrutide, and related compounds used in the Metabolic Health Program are experimental and not approved by the FDA to diagnose, treat, cure, or prevent any disease. This program is a research program, not standard medical care, and participation does not replace care from your personal physician or specialist.
No specific results are promised or guaranteed.
