Semaglutide, marketed as Wegovy for weight management, follows a structured once-weekly injection protocol designed to help your body adapt gradually to the medication. Most patients begin at a 0.25 mg dose and increase by 0.25 mg increments every four weeks, reaching maintenance doses between 1.7 mg and 2.4 mg. The frequency and dose customization depend on your individual tolerance, metabolic response, and clinical goals.

Weekly Semaglutide Injection Protocol: Standard Dosing Schedule

Semaglutide for weight management uses a once-weekly subcutaneous injection regimen, meaning you inject the medication under your skin one time each week on the same day. This consistent weekly timing allows your body to maintain steady hormone levels throughout the seven-day cycle, supporting appetite regulation and metabolic changes. The medication reaches peak concentration within 24 to 48 hours after injection, then gradually decreases over the week—which is why spacing injections exactly seven days apart maintains therapeutic benefit.

The standard titration protocol spans 16 weeks and begins at 0.25 mg per week, increasing by 0.25 mg increments every four weeks. This gradual escalation gives your gastrointestinal system time to adjust and helps minimize nausea and other early-phase side effects. Most clinical trial participants reached maintenance doses of 1.7 mg or 2.4 mg weekly by week 16, though some individuals respond well to lower maintenance doses of 1.0 mg or 1.2 mg.

Personalized Dosing Titration: When to Increase Your Injection

Your healthcare provider decides when to advance your semaglutide dose based on your tolerance, gastrointestinal symptoms, and weight loss progress rather than on a fixed calendar schedule. If you experience significant nausea, vomiting, or stomach discomfort during a four-week interval, your provider may delay the dose increase by one to two weeks to allow adaptation. Conversely, if you tolerate the current dose very well and hunger suppression wanes, moving to the next dose level earlier may improve appetite control and weight loss momentum.

PlexusDx offers the Precision Peptide Genetic Test, which identifies how your genetics influence GLP-1 receptor expression, GIPR signaling, and metabolic pathways. This insight helps your clinician predict whether you might benefit from advancing doses more quickly or maintaining a specific dose longer based on your peptide-pathway genetic profile. Personalization of the titration timeline increases the likelihood of finding your optimal dose that balances weight loss efficacy with side effect tolerance.

Maintenance Dose vs. Titration Phase: What to Expect

The titration phase lasts 16 weeks and includes five dose increases, starting at 0.25 mg and advancing by 0.25 mg weekly increases every four weeks until reaching a target maintenance dose. During titration, your appetite and food preferences shift gradually; most patients report noticeably reduced hunger, increased fullness from smaller meals, and diminished cravings for high-calorie foods. Weight loss typically accelerates during weeks 8 through 16 as you reach higher therapeutic doses.

Once you reach your maintenance dose—usually 1.7 mg, 2.0 mg, or 2.4 mg weekly—you continue injecting that same amount every seven days indefinitely or for as long as your provider recommends continued therapy. Maintenance is not an increase phase; you remain on the same dose week after week to sustain appetite suppression and metabolic benefits. Some patients maintain weight loss at 1.0 mg or 1.2 mg, while others require 2.4 mg for optimal control, reflecting biological variation in GLP-1 receptor density and sensitivity.

PlexusDx Compounded Semaglutide: Consistent Dosing at One Flat Price

PlexusDx provides compounded semaglutide injections from licensed 503A compounding pharmacies, ensuring pharmaceutical-grade purity and potency regardless of which dose level you use. Unlike brand-name Wegovy, which may have supply constraints or insurance coverage gaps, PlexusDx compounded semaglutide serves all 50 states without requiring insurance, membership fees, or employer sponsorship. Your monthly cost remains flat at $149 across all dose levels—meaning your dose may increase during titration, but your price stays the same.

Patients interested in exploring whether oral semaglutide might suit their lifestyle can also access PlexusDx Oral Semaglutide, beginning at $249 per month. PlexusDx also offers tirzepatide (a dual GLP-1/GIP receptor agonist) as an injection or oral option, plus the proprietary GLP-Squared dual-compound injection combining semaglutide and tirzepatide for patients seeking synergistic effects. All products are HSA and FSA eligible, expanding affordability for eligible account holders.

How Genetic Factors Shape Your Optimal Injection Schedule

Genetic variations in the GLP-1 receptor gene (GLP1R rs6923761), GIPR receptor gene (GIPR rs1800437), and metabolic pathways like FTO and MC4R influence how your body responds to weekly semaglutide injections. Some individuals carry genetic patterns associated with higher GLP-1 receptor expression, potentially allowing them to respond effectively at lower doses, while others have variants linked to lower receptor density or altered peptide signaling. These differences partly explain why one patient thrives on 1.0 mg weekly while another requires 2.4 mg for comparable appetite suppression.

The PlexusDx Precision Peptide Genetic Test evaluates 14 metabolic and appetite-regulation pathways across 150+ genetic insights to predict your individual response trajectory. Available as a $99 add-on after your first month of treatment, this test informs your clinician whether advancing doses might improve outcomes faster, whether you may experience fewer side effects at specific dose levels, or whether dual-compound therapy (semaglutide plus tirzepatide) might be more effective than single-agent semaglutide. Genetic personalization reduces trial-and-error in finding your optimal injection schedule.

How Your Genetics Influence GLP-1 Response

Not everyone responds to GLP-1 medications the same way. Genetic variants — including GIPR rs1800437, GLP1R rs6923761, FTO rs9939609, and MC4R rs17782313 — influence how your body processes these medications, how much weight you lose, and how you tolerate side effects. PlexusDx maps 14 pathways, 49 peptides, and 150+ genetic insights to match each patient to the right medication, dose, and lifestyle protocol for their biology. The PlexusDx Precision Peptide Genetic Test ($99 add-on after your first month of treatment) gives your provider precise insight into your peptide genetic predispositions before the first prescription is written.

Frequently Asked Questions

How often do you inject Wegovy or semaglutide for weight loss?

Semaglutide is injected once per week, every seven days, on the same day each week. You start at 0.25 mg and increase by 0.25 mg every four weeks during the 16-week titration phase, reaching a maintenance dose of 1.0 mg to 2.4 mg weekly depending on your individual tolerance and response.

Can you take Wegovy more than once a week?

No, semaglutide for weight management is designed and approved for once-weekly injection only. Taking it more frequently increases the risk of overdose, severe gastrointestinal side effects, and potential toxicity. The once-weekly schedule optimizes the balance between appetite suppression and medication tolerance.

What if I miss a weekly semaglutide injection?

If you miss your weekly injection by one to two days, take it as soon as you remember, then resume your regular weekly schedule from that new date. If you miss a dose by more than a few days, skip that missed dose and inject on your regular scheduled day the following week—do not double up on doses.

How much weight can you lose with weekly semaglutide injections?

Clinical trials show that patients on semaglutide 2.4 mg weekly lose an average of 15% to 18% of their starting body weight over 68 weeks, compared to 2% to 3% with placebo. Individual results vary based on genetics, diet, exercise, and how consistently you advance through the titration schedule.

Does PlexusDx charge more if my semaglutide dose increases?

No. PlexusDx compounded semaglutide costs $149 per month flat across all dose levels—your dose may go up during titration, but your price does not. This pricing model removes barriers to advancing your therapy to the dose that works best for your body.

Can genetic testing help predict my optimal semaglutide dose schedule?

Yes. The PlexusDx Precision Peptide Genetic Test identifies variations in your GLP-1 receptor, GIPR receptor, and metabolic genes that influence how your body responds to semaglutide dosing. This insight helps your clinician personalize your titration timeline and predict whether you might respond better at lower doses or require higher maintenance doses.
