Semaglutide, the active ingredient in Wegovy, works through a structured weekly injection schedule designed to help your body adapt while steadily increasing therapeutic effect. Most patients begin with a 0.25 mg dose and progress through five escalation steps, with each step spaced one week apart. PlexusDx delivers compounded semaglutide injections that follow this same evidence-based dosing protocol, starting at just $189 per month—no insurance required.

Understanding Your Weekly Semaglutide Injection Schedule

Semaglutide follows a consistent once-weekly injection rhythm, meaning you administer one dose every seven days on the same day each week. This predictable schedule makes it easier to build the habit into your routine—many patients choose a specific day like Monday morning or Friday evening. The weekly frequency allows your body to maintain steady medication levels while your healthcare provider monitors your response and tolerance.

The standard titration ladder spans 16-20 weeks and includes five dose increases. Starting at 0.25 mg in week one, your dose may escalate to 0.5 mg, 1 mg, 1.5 mg, and finally 2 mg based on your individual tolerance and clinical goals. Your dose may need to go up over time, but your monthly price stays fixed—PlexusDx charges one flat rate regardless of which step you're on in the titration process.

The Five-Step Semaglutide Titration Protocol

Week one through four involve a 0.25 mg weekly injection, allowing your digestive system and appetite-regulating pathways to adjust gently. Weeks five through eight increase to 0.5 mg per week as your body develops tolerance to the medication's effects on appetite and blood sugar. This gradual approach reduces the intensity of nausea and other side effects that patients sometimes experience when doses escalate too rapidly.

Weeks nine through twelve bring a 1 mg weekly dose, marking the middle phase where most patients report meaningful appetite reduction and early weight loss momentum. Weeks thirteen through sixteen raise the dose to 1.5 mg weekly, intensifying GLP-1 receptor activation in your brain and gut. The final maintenance dose of 2 mg weekly (weeks seventeen onward) represents the typical therapeutic target for sustained weight loss, though some individuals find effective results at lower maintenance doses depending on their genetic peptide pathways.

Factors That Affect Your Injection Timing and Dosing

The PlexusDx Precision Peptide Genetic Test analyzes GLP1R, and GIPR — variants that relate to GLP-1 and related signaling pathways. It does not predict your response to tirzepatide or determine your dose; it offers pathway-level context for a conversation with your provider. Genetics is a guide, not a guarantee.

Gastrointestinal side effects, baseline metabolic health, and concurrent medications can slow your progression or require dose pauses. If you experience severe nausea, vomiting, or constipation, your clinician may recommend staying at your current dose for an extra week or two before advancing. Conversely, patients tolerating early doses well often move through the schedule as planned, reaching their target maintenance dose by week sixteen to eighteen.

Maintaining Your Weekly Injection Routine and Storage

Once you reach your maintenance dose of 2 mg weekly, you continue one injection every seven days indefinitely—there is no cycling off or break period unless directed by your healthcare provider. Consistency matters: taking your injection on the same day each week keeps your medication levels stable and reinforces the habit loop. Many patients set phone reminders or link their injection day to an existing weekly ritual like meal prep Sunday or Friday evening self-care.

Storing your semaglutide requires refrigeration at 36°F to 46°F (2°C to 8°C) until first use, then you can keep it at room temperature up to 86°F (30°C) for 28 days. Each pen or vial comes with clear storage instructions from your compounding pharmacy. If you travel, a portable cooling case keeps your medication stable, and you can request vacation supplies or emergency replacements from PlexusDx's patient support team.

How Your Genetics Relate to GLP-1 Pathways

Not everyone responds to GLP-1 medications the same way. Genetic variants — including GIPR rs1800437, GLP1R rs6923761, 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 ($99 add-on after your first month of treatment) gives you and your provider pathway-level genetic context to support a more personalized conversation. Genetics is a guide, not a guarantee.

Add a Precision Peptide Genetic Test for $99 to personalize your protocol from day one.

Frequently Asked Questions

How many times per week do you inject semaglutide?

You inject semaglutide exactly once per week on the same day each week. This weekly frequency is built into the medication's pharmacology and the clinical trial evidence that proved its safety and efficacy for weight loss.

Can you skip a week or take semaglutide injections twice weekly?

No—skipping weeks or doubling up doses disrupts your steady-state medication levels and can increase side effects or reduce therapeutic benefit. If you miss an injection, take it as soon as you remember following the missed-dose instructions on your pharmacy label, then skip the missed dose and resume your normal weekly schedule.

How long does it take to reach the full 2 mg maintenance dose?

The standard titration schedule takes 16-20 weeks to reach 2 mg maintenance, with one dose increase every four weeks. PlexusDx clinicians may adjust this timeline based on your tolerance and genetic testing results from the Precision Peptide Genetic Test.

Is semaglutide injection more effective than oral versions?

Injectable semaglutide delivers higher bioavailability and more direct GLP-1 receptor activation than oral formulations, typically resulting in faster weight loss in clinical trials. PlexusDx offers both compounded semaglutide injections (at $189/mo month-to-month, or from $149/mo on the 6-month plan) and oral semaglutide (at $289/mo month-to-month, or from $249/mo on the 6-month plan) so you can choose based on preference and lifestyle.

What does the Precision Peptide Genetic Test reveal about my injection response?

No — the Precision Peptide Genetic Test does not predict your response to semaglutide or any specific medication. It analyzes pathway-level variants (GLP1R, and GIPR) that relate to the biology involved, offering context for a conversation with your provider rather than a prediction.
