What to expect

Your Semaglutide timeline.

Weeks 1 to 4

Initiation

If your provider determines you're eligible, treatment typically begins at the lowest titration step. Many clients report reduced cravings within the first two weeks; some experience GI adjustment.

Months 1 to 3

Active weight loss

Your provider may adjust dosing based on tolerability and response. Your coach supports protein-forward nutrition and resistance-training guidance to preserve lean mass.

Months 3 to 6

Metabolic improvement

Follow-up labs help your provider evaluate metabolic markers, insulin sensitivity, HbA1c, lipids. Body-composition shifts become visible. Protocol refined.

Month 6+

Maintenance & off-ramp

Long-term planning is individualized. Some clients continue on a maintenance plan; others taper. Your coach helps build the lifestyle infrastructure that supports results.

How it works

From sign-up to treatment.From sign-up to your first dose.

Take the assessment

45-min intake with your dedicated health coach. A free health-score quiz is available before the paid intake.

Get your labs drawn

Complete lab panel ordered by your provider, drawn at any of 4,000 partnered lab locations nationwide. Results typically return within 14 days.

Provider reviews your results

A licensed medical provider reviews your labs and history to evaluate whether Semaglutide is appropriate for you. Eligibility and any prescription are determined at the provider's discretion.

If eligible, treatment ships to your door

If your provider prescribes Semaglutide, it ships from a licensed pharmacy. Your coach supports you through follow-up labs and ongoing monitoring.

The baseline panel.

Every Marek client receives this baseline panel before a provider review. Your provider may add additional biomarkers based on your health history, symptoms, and goals, pulling from 1,000+ available markers. See more biomarkers →

The science

How Semaglutide works.

Semaglutide is a long-acting GLP-1 receptor agonist. Activating GLP-1 receptors in the hypothalamus reduces hunger signaling and increases satiety; slowed gastric emptying extends the feeling of fullness after meals.

GLP-1 activation also engages pancreatic beta-cell function and improves glucose-dependent insulin secretion. The combined effect is the mechanism by which semaglutide is associated with weight reduction and metabolic improvement in published trials.

In the STEP 1 trial, average body-weight reduction reached approximately 15% at 68 weeks. The SELECT trial also demonstrated a reduction in major cardiovascular events.

Eligibility, dosing, and outcomes vary. Any prescription is at the discretion of a partnered licensed medical provider based on your labs and medical history.

Clinical evidence

The research behind Semaglutide.

STEP 1: Semaglutide for weight loss

New England Journal of Medicine (2021)

1,961 adults with overweight or obesity. The treatment group experienced a mean body-weight reduction of approximately 14.9% at 68 weeks.

SELECT: Cardiovascular outcomes in non-diabetic patients

New England Journal of Medicine (2023)

17,604 adults with overweight or obesity and pre-existing cardiovascular disease. Semaglutide was associated with a ~20% reduction in major adverse cardiovascular events.

SUSTAIN-7: Semaglutide vs. dulaglutide

Lancet Diabetes & Endocrinology (2018)

1,201 patients with type 2 diabetes. Semaglutide showed greater A1c reduction and weight loss than dulaglutide across study doses.

FAQ

Quick answers.

Eligibility, dose, and duration are determined by a partnered licensed medical provider based on your complete labs and medical history. A prescription is not guaranteed, your provider may recommend Semaglutide, a different therapy, or a non-pharmacologic approach.
Clinical trials (STEP program) showed average weight loss of 15 to 17% of body weight over 68 weeks. With Marek's coached approach, including nutrition guidance and muscle preservation, many clients achieve similar or better results while maintaining lean mass. Individual response varies.
Some lean-mass loss is possible on any rapid weight-loss intervention. Marek's coached approach emphasizes protein-forward nutrition, resistance-training guidance, and body-composition tracking, supporting lean-mass preservation rather than just scale weight.
Commonly reported side effects include nausea, reduced appetite, and other GI symptoms during titration. Less common but serious risks include pancreatitis and gallbladder disease. Your provider reviews your history to evaluate whether Semaglutide is appropriate, and your coach helps monitor symptoms throughout.
Studies show some weight regain after discontinuation. Your protocol includes an exit strategy: gradual taper, established nutrition habits, metabolic-health monitoring, and optional maintenance dosing. The goal is sustainable results, not medication dependence.
Pricing starts with a $299 intake assessment with your dedicated health coach. Lab pricing starts at $450. If your provider determines a prescription is appropriate, medication cost is separate and varies by dose. HSA/FSA eligible.
