Wegovy (semaglutide) follows a step-wise dosing schedule that typically begins at 0.25 mg once weekly and escalates over 16 weeks to a maintenance dose of 2.4 mg weekly. This gradual titration helps your body adjust to the medication while reducing nausea and other gastrointestinal effects that often occur with higher starting doses.

Standard Wegovy Dosing Schedule and Timeline

The standard Wegovy protocol divides the first four months into four distinct phases, each lasting approximately four weeks. Weeks 1–4 introduce 0.25 mg weekly, weeks 5–8 move to 0.5 mg weekly, weeks 9–12 reach 1 mg weekly, and weeks 13–16 climb to 1.7 mg weekly. After week 16, most patients maintain 2.4 mg as their final therapeutic dose, though some may stop at an earlier tier if they experience significant results or intolerable side effects.

Your healthcare provider may adjust this timeline based on your tolerance, weight loss progress, and metabolic response. Some patients benefit from staying at a lower dose for an extended period before moving forward, while others may skip intermediate steps if well tolerated. The key principle is individual titration—not everyone follows the same pace.

Why Doses Increase Gradually in GLP-1 Therapy

Gradual dose escalation exists for two critical reasons: safety and efficacy. Your GLP-1 receptors in the brain, gut, and pancreas require time to adapt to medication presence, which reduces the intensity of nausea and vomiting during the first weeks of treatment. Clinical trials show that starting at full dose causes severe gastrointestinal distress in up to 40% of patients, often leading to discontinuation before meaningful weight loss occurs.

The stepwise approach also allows your body to develop tolerance to the appetite-suppression signal while you learn new eating behaviors. Research indicates that patients who follow gradual titration achieve better long-term adherence and more sustainable weight loss compared to those forced to start at higher doses. This timing matches the time your metabolism needs to shift from calorie surplus to metabolic stability.

Factors That Influence Your Personalized Dosing Path

Not all patients respond identically to the standard dosing ladder. Your age, kidney function, baseline metabolic rate, and genetic predisposition to GLP-1 receptor sensitivity all shape how quickly you should advance. Patients with a history of severe gastrointestinal conditions may require extended time at lower doses, while those with rapid gastric emptying may tolerate faster escalation. Body composition, insulin resistance severity, and concurrent medications also modify the ideal progression.

The PlexusDx Precision Peptide Genetic Test ($298) analyzes GIPR, FTO, and MC4R — variants that relate to GLP-1 and related signaling pathways. It does not predict your response to Wegovy or determine your dose; it offers pathway-level context for a conversation with your provider. Genetics is a guide, not a guarantee.

Compounded Semaglutide vs. Branded Wegovy Dosing

PlexusDx delivers compounded semaglutide from licensed 503A compounding pharmacies, which produce the same active ingredient as branded Wegovy using identical FDA-grade materials and quality standards. The dosing principles remain unchanged—your titration schedule follows the same gradual escalation, and your prescriber maintains full control over advancement timing. Compounded options serve all 50 states without insurance requirements, making personalized dosing accessible regardless of coverage status.

PlexusDx compounded semaglutide injections are $189/mo month-to-month, or from $149/mo on the 6-month plan flat pricing across all commitment tiers. Your dose may need to go up over weeks 1–16 as you titrate toward maintenance, but your monthly price stays the same—you never pay more as your dose increases. This transparent pricing removes the financial barrier that sometimes prevents patients from staying on medication long enough to reach their optimal dose.

Managing Side Effects During Dose Escalation

Nausea peaks during the first two weeks at each new dose level, then typically fades within days as your body acclimates. Eating smaller, lower-fat meals; staying hydrated; and taking medication on the same day each week help minimize gastrointestinal upset. If nausea persists beyond one week at a new dose, inform your prescriber—you may benefit from extended time at your current dose before advancing, or your genetic profile may suggest an alternative compound better suited to your physiology.

The PlexusDx Precision Peptide Genetic Test analyzes FTO, and MC4R — variants that relate to GLP-1 and related signaling pathways. It does not predict your response to semaglutide or determine your dose; it offers pathway-level context for a conversation with your provider. Genetics is a guide, not a guarantee.

How Your Genetics Relate to GLP-1 Pathways

Not everyone responds to GLP-1 medications the same way. Genetic variants — including GIPR rs1800437, FTO rs9939609, and MC4R rs17782313 — relate to the biological pathways these medications act on. These are pathway-level associations only and do not predict how much weight you will lose or how you will respond to any specific medication. PlexusDx maps 14 pathways, 49 peptides, and 150+ genetic insights so you and your provider can see how your genes relate to these pathways. It does not recommend, prescribe, or determine which medication, dose, or peptide is right for you. The PlexusDx Precision Peptide Genetic Test ($298) gives you and your provider pathway-level genetic context to support a more personalized conversation. Genetics is a guide, not a guarantee.

Frequently Asked Questions

What happens if I can't tolerate my dose increase?

Contact your prescriber before your next scheduled increase. Staying at your current dose longer—sometimes 2–4 additional weeks—allows your body to adapt fully. Many patients successfully advance after this extended acclimatization period. Your prescriber may also explore whether your genetic profile suggests a compound better matched to your physiology.

Can I stay on a lower dose than 2.4 mg if it works for me?

Yes. Clinical evidence shows meaningful weight loss occurs at doses as low as 1 mg weekly for some patients, particularly those with certain genetic variants. If you reach your weight loss goal at 1.7 mg or 2 mg and tolerate it well, your prescriber may recommend maintaining that dose indefinitely rather than advancing further.

Does PlexusDx charge more if my dose increases each month?

No. PlexusDx compounded semaglutide injections are priced flat at $189/mo (or $149/mo on the 6-month plan) regardless of whether you're at 0.25 mg or 2.4 mg—your dose may go up, but your price won't. Oral semaglutide is $289/mo flat, and all medications are HSA/FSA eligible with no insurance required.

How does the Precision Peptide Genetic Test relate to your GLP-1 pathway?

No — the Precision Peptide Genetic Test does not predict your response to Wegovy or any specific medication. It analyzes pathway-level variants (GIPR, FTO, and MC4R) that relate to the biology involved, offering context for a conversation with your provider rather than a prediction.

Is compounded semaglutide dosed the same way as Wegovy?

Yes. PlexusDx compounded semaglutide from licensed 503A pharmacies contains identical active pharmaceutical ingredients and follows the same titration schedule as Wegovy. The gradual escalation, timing, and dose adjustments remain unchanged—only the source and pricing differ, with PlexusDx offering transparent flat-rate pricing across all commitment tiers.
