Case Studies
Our Unique Approach to Weight Loss Peptide Therapy
We Provide The Full Spectrum of GLP-1 Peptides, Each With Unique Benefits:
Semaglutide (Wegovy) for moderate weight loss with GLP-1 activation:
- Semaglutide is a GLP-1 agonist that has been studied at different doses, primarily for obesity management and type 2 diabetes.
Tirzepatide (Mounjaro) for enhanced weight loss with dual GLP-1 and GIP action:
- Tirzepatide is a dual agonist (GLP-1 and GIP) that has shown exceptional efficacy in weight loss.
Retatrutide for unparalleled fat loss, activating GLP-1, GIP, and glucagon pathways:
- Retatrutide, a triple agonist (GLP-1, GIP, and glucagon), is still in clinical trials but has demonstrated rapid and extensive weight loss.
Why Muscle Preservation During GLP-1 Use Matters
Our Advanced Muscle-Preserving Peptide Strategy
Muscle plays a critical role in maintaining a healthy metabolism, supporting physical strength, and contributing to an aesthetically toned physique.
Unfortunately, traditional weight loss methods — even those involving advanced peptides — can result in significant muscle loss.
Studies have shown that weight loss with popular peptides, such as Semaglutide (Wegovy), can lead to 25-30% of the weight lost being lean body mass, including muscle.
We go beyond standard GLP-1 treatments by using a multi-peptide approach designed to not only burn fat but also protect and support your lean muscle mass.
Promoting Natural Growth Hormone Release to Preserve Muscle:
We combine GLP-1 peptides with growth hormone-releasing peptides (GHRPs) that naturally stimulate the production of human growth hormone (HGH).
This helps:
- Protect existing muscle tissue during periods of calorie restriction.
- Promote muscle repair and growth, even as you lose fat.
- Enhance overall body composition for a lean, toned look.
By focusing on muscle preservation, we ensure that your weight loss journey leaves you not just lighter but stronger, healthier, and more confident.
No Cookie-Cutter Dosages — Pure Vial Form for Precision
Why Vial Form Matters:
Unlike many providers who rely on pre-filled pens with fixed dosages, we take a more advanced and flexible approach.
Our peptides come in pure vial form, containing only the raw amino acid chains without fillers, preservatives, or unnecessary additives.
This means you receive peptides in their most potent and bioavailable state, allowing us to tailor every dosage to fit your body’s unique metabolic requirements.
With pre-filled pens, you’re limited to standardised doses that may not align with your weight loss goals or body composition.
By using pure vials, we have the freedom to adjust your dosage incrementally, ensuring that your treatment plan evolves as your body adapts, maximizing effectiveness.
By eliminating fillers and unnecessary additives found in pre-filled pens, we maintain the highest level of peptide purity.
This reduces the risk of adverse reactions and ensures that your body absorbs and responds efficiently to the treatment.
Side Effects of GLP-1s: Separating Fact from Fiction
Why Side Effects Are Less Frequent Than Perceived
Gradual Dose Titration Reduces Incidence:
- Most side effects occur when the dosage is increased too quickly.
- By starting with a low dose and gradually titrating up, the likelihood and severity of nausea or other GI symptoms are dramatically reduced.
Temporary Adjustment Phase:
- The body typically adjusts to GLP-1 peptides within the first few weeks of treatment. As the digestive system becomes accustomed to slower gastric emptying (one of the primary effects of GLP-1), symptoms often resolve without intervention.
Individual Tolerance:
- Clinical studies show that only a subset of individuals experience any noticeable GI issues, and most report these as mild and short-lived. Patients with a history of sensitive stomachs may be slightly more prone to initial discomfort.
Clinical Data on Tolerability:
Studies have demonstrated that the majority of individuals tolerate GLP-1 therapy well, with severe or persistent gastrointestinal issues being quite rare.

Targeted Weight Loss Peptides Protocols
Let Science Lead the Way to Sustainable Weight Loss
Your Questions Answered: Weight Loss Peptides FAQ
1. What Is Weight Loss Peptide Therapy?
Weight Loss Peptide Therapy uses scientifically selected peptides — short chains of amino acids — to target biological functions that influence metabolism, appetite regulation, fat oxidation, and hormonal balance. These peptides work with your body’s natural systems to support healthy, sustainable weight loss without extreme diets or stimulants.
2. Is It Safe?
Yes — when used under clinical guidance, weight loss peptide therapy is considered safe and effective. At Nūūtro, every protocol is based on clinical research, tailored to your physiology, and sourced from EU GMP-approved or FDA-grade USA laboratories.
3. What Can Weight Loss Peptides Help With?
Weight loss peptides can support a broad range of metabolic and hormonal goals, including:
- Reducing body fat and visceral fat
- Controlling appetite and cravings
- Improving insulin sensitivity
- Enhancing energy and stamina
- Supporting lean muscle retention
- Rebalancing metabolic hormones like leptin, ghrelin, and insulin
4. How Does the 3-Month Protocol Work?
Your journey begins with a consultation, in-depth health review, and optional lab work. We then curate a personalised peptide plan — using pre-mixed vials or pens — ready for pickup at our Mayfair clinic.
Throughout the 3 months, you’ll receive ongoing clinical support, with regular check-ins and the flexibility to adapt your protocol as your body responds.
5. Do I Need Blood Work Before Starting?
In most cases, yes. Blood tests give us valuable insight into your metabolic markers, hormone levels, and overall health — allowing us to design a protocol that’s not only safe, but highly effective.
6. When Will I Start Seeing Results?
Most clients begin noticing improvements in appetite control, energy, and mood within 2–4 weeks. More visible changes in body composition — such as fat loss and muscle tone — typically develop across the 3-month protocol. Consistency and guided support are key to optimal results.
7. Are the Peptides Injectable?
Yes. Most weight loss peptides are administered through painless subcutaneous injections using either pre-loaded pens or professionally prepared vials. Our team provides full guidance to ensure safe and easy self-administration.
8. Can My Protocol Be Adjusted Over Time?
Absolutely. We maintain a tight feedback loop throughout your plan and will adjust dosages, timing, or peptide selection based on how your body responds. Your plan evolves with you.
9. Can I Combine Peptides with Other Therapies?
Yes. Many clients pair weight loss peptides with nutritional therapy, gut support, hormone balancing, or biohacking modalities for enhanced results. We’re happy to collaborate with your existing wellness team or design a full-stack protocol in-house.
10. How Much Does It Cost?
Weight loss peptide protocols at Nūūtro start from £400 per month, inclusive of your initial consultation, expert support, and clinically prepared peptide doses. Lab work or additional services may vary.
11. Are Peptides Legal in the UK? Do They Require a Prescription?
Peptides are legal in the UK, though they exist in a regulatory grey zone. Most peptides used for cosmetic or wellness purposes do not require a prescription. At Nūūtro, we strictly source EU GMP- and FDA-grade peptides, and all usage is guided by expert clinicians to ensure safety and compliance with UK frameworks.
