Understanding the Science

What Are GLP-1 Peptides?

GLP-1 (Glucagon-Like Peptide-1) is a naturally occurring hormone that plays a crucial role in regulating appetite, blood sugar, and metabolism.

Natural Hormone Mimic

GLP-1 peptides work by mimicking a hormone your body naturally produces in the gut after eating. They enhance your body's own satiety signals.

Appetite Regulation

By activating GLP-1 receptors in the brain, these peptides reduce hunger signals and increase feelings of fullness, making it easier to eat less naturally.

Metabolic Benefits

Beyond weight loss, GLP-1 peptides improve insulin sensitivity, help regulate blood sugar levels, and may provide cardiovascular protection.

"GLP-1 receptor agonists represent a paradigm shift in obesity treatment, addressing the biological drivers of excess weight rather than relying solely on willpower."

— New England Journal of Medicine, 2024

Mechanism of Action

How Semaglutide & Tirzepatide Work

Understanding the science behind these peptides helps you make informed decisions about your weight loss journey.

GLP-1

Semaglutide

Single-receptor agonist

1

Activates GLP-1 Receptors

Binds to receptors in the brain's appetite center (hypothalamus)

2

Slows Gastric Emptying

Food stays in stomach longer, promoting sustained fullness

3

Improves Insulin Response

Enhances glucose-dependent insulin secretion

Average Weight Loss 15-17%

STEP trials (68-week treatment period)

GIP+GLP

Tirzepatide

Dual-receptor agonist

1

Dual Receptor Activation

Activates both GIP and GLP-1 receptors for enhanced effect

2

Enhanced Satiety Signals

Stronger appetite suppression through dual pathways

3

Improved Fat Metabolism

GIP receptor activation enhances fat tissue metabolism

Average Weight Loss 20-22%

SURMOUNT trials (72-week treatment period)

Once-Weekly Injection

Both peptides are administered via a simple subcutaneous injection once per week. Our clinical team will guide you through the proper self-injection technique during your consultation.

Common Questions

Frequently Asked Questions

Semaglutide is a GLP-1 receptor agonist, while Tirzepatide is a dual GIP/GLP-1 receptor agonist. This means Tirzepatide activates two hormonal pathways instead of one, which clinical trials show leads to greater average weight loss (20-22% vs 15-17%). Tirzepatide may be more effective for some individuals, but both are clinically proven.

Both medications are administered via a simple subcutaneous injection once per week. The injection is typically given in the abdomen, thigh, or upper arm. Our clinical team will provide detailed video guidance and can walk you through the process via WhatsApp during your first dose.

The most common side effects are gastrointestinal: nausea, vomiting, diarrhea, and constipation. These are typically mild to moderate and decrease over time as your body adjusts. Starting at a lower dose and gradually increasing helps minimize side effects. Our doctors will guide you through proper dose titration.

Most patients notice reduced appetite within the first 1-2 weeks. Measurable weight loss typically begins within 4-8 weeks. Clinical trials showed progressive weight loss over 68-72 weeks, with most weight loss occurring in the first 6-12 months. Individual results vary based on starting weight, diet, and activity level.

GLP-1 medications have been studied extensively in clinical trials lasting up to 2+ years. They are FDA-approved for long-term use in weight management. However, like any medication, they should be used under medical supervision. Our doctors will monitor your progress and can adjust treatment as needed.

We source compounded peptides from verified facilities and conduct independent third-party lab testing on every batch. Each shipment includes proper cold-chain packaging with temperature indicators. Certificates of analysis showing purity levels (99%+) are available upon request.

Yes, we deliver to all states in Nigeria. Lagos deliveries typically arrive within 24-48 hours. Other major cities (Abuja, Port Harcourt, Kano, etc.) receive deliveries within 2-3 business days. All shipments use temperature-controlled packaging to ensure medication integrity.
