Description

Retatrutide 10MG Self-Injectable Pen is a next-generation triple-agonist peptide (GLP-1/GIP/Glucagon) delivered in a convenient, pre-filled pen. Engineered for research-grade precision, this once-weekly subcutaneous injection targets multiple metabolic pathways simultaneously — making it the most comprehensive peptide available for whole-body transformation.

Experience dramatic fat loss including stubborn visceral fat, while unlocking powerful benefits across every system: accelerated metabolism, reduced inflammation, enhanced mental clarity, improved mood and anxiety relief, radiant skin, stronger hair, reduced bloating, and sustained all-day energy. Retatrutide doesn't just help you lose weight — it helps you feel younger, sharper, and more alive.

Each pen contains 10mg of pharmaceutical-grade Retatrutide in a ready-to-use GoQuick subcutaneous delivery system. No mixing, no vials, no guesswork — just click and inject.

How do I use it?

Inject subcutaneously once per week in the abdomen, thigh, or upper arm. Rotate injection sites each week. The pre-filled GoQuick pen requires no reconstitution — simply remove the cap, dial your dose, and inject.

Titration schedule: Start at a low dose and gradually increase over several weeks to minimize side effects and allow your body to adjust. Refer to the included titration guide for week-by-week dosing instructions.

Store refrigerated (2–8°C). Allow pen to reach room temperature for 15 minutes before injection. For research purposes only.

Key Benefits

Fat & Weight Loss: Triple-receptor activation drives superior fat oxidation including deep visceral fat that other peptides miss. Clinical data shows significant total body weight reduction.

Anti-Aging & Skin: Promotes cellular repair, collagen synthesis, and healthier skin turnover — resulting in a more radiant, youthful complexion and stronger hair growth.

Energy & Stamina: Optimized metabolic signaling delivers clean, sustained energy throughout the day without crashes or jitters.

Mental Health: Users report reduced anxiety, improved mood, sharper focus, and relief from depressive symptoms — likely driven by improved metabolic and inflammatory markers.

Inflammation & Bloating: Powerful anti-inflammatory action reduces chronic systemic inflammation and eliminates water retention and gut bloating.

Shipping & Returns

Processing: 2-4 hours. Signed & tracked shipping: 3-5 business days with cold chain packaging.

Full 90-day return policy — no questions asked. Your satisfaction is guaranteed.

Recommended Titration Schedule

Follow this week-by-week dosing guide to gradually build up to your optimal dose. Starting low and titrating up minimizes side effects and maximizes results.

Research-backed. Science-driven.

Retatrutide is the world's first triple-agonist peptide, simultaneously activating GLP-1, GIP, and glucagon receptors. This unique mechanism drives unmatched fat oxidation, metabolic optimization, and systemic anti-inflammatory effects that go far beyond simple weight loss.

Published clinical research demonstrates up to 24% total body weight reduction — the highest of any peptide therapy studied to date. Participants also reported improvements in cardiovascular markers, liver fat reduction, mood enhancement, and metabolic biomarkers across the board.

Frequently asked questions

When will I start seeing results?
Most users notice reduced appetite and less bloating within the first 1–2 weeks. Visible fat loss typically begins around weeks 3–4, with significant body composition changes between weeks 8–12. Anti-aging and skin benefits usually become noticeable after 4–6 weeks of consistent use.
How is Retatrutide different from semaglutide or tirzepatide?
Retatrutide is a triple-agonist that activates GLP-1, GIP, and glucagon receptors simultaneously. Semaglutide (Ozempic/Wegovy) only activates GLP-1, and tirzepatide (Mounjaro) activates GLP-1 and GIP. The addition of glucagon receptor activation drives significantly greater fat oxidation, particularly of visceral fat, and enhances metabolic rate.
What are the common side effects?
The most common side effects are mild and typically occur during the titration phase: nausea, decreased appetite, and mild GI discomfort. These usually subside as your body adjusts. Following the recommended titration schedule significantly minimizes side effects.
How do I store the pen?
Store your pen refrigerated between 2–8°C (36–46°F). Do not freeze. Before injection, allow the pen to reach room temperature for approximately 15 minutes. Once in use, the pen can be kept at room temperature (below 25°C/77°F) for up to 28 days.
Will I experience hair loss or muscle loss?
Retatrutide's mechanism preferentially targets fat tissue over lean muscle. Many users actually report improved hair quality and growth. Maintaining adequate protein intake and light resistance training is recommended to preserve muscle mass during your transformation.
Can Retatrutide help with anxiety and depression?
Many users report significant improvements in mood, anxiety, and depressive symptoms. This is likely due to reduced systemic inflammation, improved metabolic health, better sleep quality, and the confidence that comes with visible physical transformation. While not a replacement for mental health treatment, it can be a powerful complement.
Is this product for research purposes only?
Yes. Longevity Labs Retatrutide is sold strictly for research purposes. It is not intended for human consumption, diagnosis, or treatment of any medical condition. All purchasers must confirm they understand this designation before ordering.
