Semaglutide is administered as a once-weekly subcutaneous injection, which translates to approximately four injections per month during active treatment phases. The frequency remains constant, but your dose may need to go up as your provider adjusts your therapy over 16 to 20 weeks of titration to reach your therapeutic target.

Standard Semaglutide Injection Schedule: Four Shots Monthly

The standard semaglutide injection protocol calls for one subcutaneous shot every seven days, resulting in roughly four injections per month. This weekly cadence allows the medication to maintain steady-state blood levels and activate GLP-1 receptors throughout your digestive and metabolic system. Your first injection typically begins at a lower microdose, then increases in small increments every week or two until you reach your maintenance dose.

Unlike insulin or other daily injectable medications, semaglutide's long half-life of about seven days means you only need to remember one injection day per week. Most patients choose the same day each week—Monday morning or Friday evening—to build consistency into their routine. PlexusDx compounded semaglutide injections start at $149 per month, and your price remains flat whether your provider increases your dose strength during titration.

How Dose Titration Works Over 16 to 20 Weeks

Semaglutide dosing follows a progressive titration schedule designed to minimize gastrointestinal side effects while maximizing weight loss efficacy. Your first month typically involves microdoses of 0.25 mg weekly, advancing to 0.5 mg in month two, then to 1.0 mg by weeks five through eight. Many patients continue climbing to 1.7 mg or 2.4 mg over the following weeks, with adjustments based on your individual metabolic response and tolerance.

The titration process means you're receiving the same four injections per month, but each needle contains a progressively stronger dose as your body adapts. Clinical trials show that patients who complete the full titration schedule experience greater sustained weight loss than those who jump to higher doses immediately. Your provider monitors your progress at regular intervals and may slow the titration pace if side effects emerge or accelerate it if you're tolerating the medication well.

Why Weekly Injections Outperform Daily Oral Medications

Weekly semaglutide injections deliver more consistent drug exposure than daily oral formulations because the subcutaneous route bypasses liver metabolism and enters your bloodstream directly. This means four monthly injections maintain therapeutic levels better than remembering to take a daily pill, which patients often skip or forget. Studies comparing weekly injections to oral semaglutide found that injection patients achieved 3% to 5% greater weight loss over 68 weeks.

The injection method also allows for more precise dose escalation, since each vial can be manufactured to exact micrograms and delivered in full. Oral tablets lose potency through digestive breakdown, so achieving the same clinical effect requires higher pill doses—and higher costs. PlexusDx sources compounded semaglutide injections from licensed 503A compounding pharmacies, ensuring pharmaceutical-grade sterility and accurate dosing for every monthly supply.

Personalized Dosing Through PlexusDx Genetic Testing

Not all patients respond identically to four weekly injections at the standard dose ladder; some reach target weight loss faster, while others need additional time or a higher final dose. PlexusDx Precision Peptide Genetic Test identifies your genetic predispositions across 14 metabolic pathways, including GLP-1 receptor sensitivity (GLP1R rs6923761), glucose-dependent insulinotropic polypeptide signaling (GIPR rs1800437), and melanocortin-4 receptor variants (MC4R rs17782313). This $99 add-on after your first month of treatment helps your provider predict whether standard titration will work for you or if a modified schedule better suits your biology.

Patients with specific genetic variants may see superior results with more gradual titration, higher maintenance doses, or even combination therapies like PlexusDx GLP-Squared Injection (semaglutide plus tirzepatide). Understanding your peptide genetics removes guesswork from your treatment plan and helps your provider confidently adjust your four monthly injections to match your unique metabolic profile.

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.

Access Personalized GLP-1 Care Through PlexusDx

PlexusDx offers six prescription GLP-1 protocols to all 50 states — no membership, no insurance required, async intake or live consult. The Semaglutide Injection starts at $149/mo. Medications are dispensed from licensed 503A compounding pharmacies following strict quality and safety standards. Add a Precision Peptide Genetic Test for $99 to personalize your protocol from day one.

Frequently Asked Questions

How many semaglutide shots will I need to give myself each month?

You'll receive four weekly injections per month, meaning one shot every seven days. Your price stays flat at $149 per month or higher depending on your commitment tier, regardless of whether your dose strength increases during titration.

What happens if I miss one of my weekly semaglutide injections?

Missing a single weekly injection typically causes minimal disruption because semaglutide has a seven-day half-life, so some medication remains active in your system. If you miss an injection, take it as soon as you remember, then resume your regular weekly schedule. Contact your PlexusDx provider if you miss multiple doses, as they may adjust your overall plan.

Does my semaglutide dose increase mean I'll pay more per month?

No. PlexusDx pricing follows the principle: your dose may need to go up, your price won't. Your monthly fee remains flat whether you're on microdose protocol, standard titration, or maintenance therapy, with compounded semaglutide injections starting at $149 per month.

Can I switch from four weekly injections to something else if they're not working?

Yes. PlexusDx offers multiple options including oral semaglutide, compounded tirzepatide injections, and dual-compound GLP-Squared formulations. Your provider can recommend alternatives based on your response after 16 to 20 weeks of titration or if you experience intolerable side effects.

How does the Precision Peptide Genetic Test help predict my injection response?

PlexusDx Precision Peptide Genetic Test analyzes variants like GLP1R rs6923761, GIPR rs1800437, and MC4R rs17782313 to reveal your receptor sensitivity and glucose metabolism patterns. This $99 add-on helps your provider forecast whether standard four-injection-monthly titration will suit you or if a personalized approach works better for your genetic profile.
