Semaglutide Dosage Chart: Week-by-Week Titration Guide
Six months of semaglutide protocol comes down to one number per week. This semaglutide dosage chart breaks down the complete week-by-week titration — starting dose, escalation schedule, maintenance ceiling, and the unit conversions that compounded users actually need.
Key Takeaways
- Semaglutide dosing starts at 0.25mg per week and escalates by 0.25–0.5mg every four weeks until reaching maintenance (typically 1.0–2.4mg weekly).
- Most users see meaningful weight loss between weeks 4–8, when they reach the 1.0–1.5mg dose range.
- Exceeding the 2.4mg weekly ceiling does not improve weight loss outcomes and significantly increases nausea and cardiovascular side effect risk.
- Steady escalation beats speed — moving up too fast is the primary driver of early discontinuation.
- Logging dose timing, concentration, and weekly wellness data is the only way to distinguish real protocol progress from placebo effect.

What Is the Standard Semaglutide Dosage Chart?
The standard subcutaneous semaglutide titration begins at 0.25mg once weekly for four weeks, then escalates in 0.25–0.5mg increments every four weeks. The maintenance ceiling is 1.0mg for diabetes management (Ozempic) or 2.4mg for weight management (Wegovy). Full titration to maximum dose takes 16–20 weeks.
Here's the complete week-by-week schedule, with standard unit equivalents for U-100 insulin syringes at 2.5 mg/mL concentration — the most common compounded semaglutide formulation:
| Week | Dose (mg) | Units at 2.5 mg/mL | Phase |
|---|---|---|---|
| 1–4 | 0.25 mg | 10 units | Starting |
| 5–8 | 0.50 mg | 20 units | Escalation |
| 9–12 | 1.00 mg | 40 units | Escalation |
| 13–16 | 1.25 mg | 50 units | Escalation |
| 17–20 | 1.75 mg | 70 units | Escalation |
| 21+ | 2.40 mg | 96 units | Maintenance |
Worth knowing: Units depend on your vial's concentration, not a universal number. A 2.5 mg/mL vial delivers 0.25mg per 10 units. A 5 mg/mL vial delivers 0.5mg per 10 units. Confirm your concentration before every draw — concentration mismatches are the most common compounded semaglutide dosing error.

How Does Semaglutide Dosage Escalate Over Time?
Semaglutide dose escalation follows a four-week hold-then-increase structure. Each level is held for a minimum of four weeks before advancing. This pace allows the GI tract to develop tolerance to the drug's gastric-slowing effects — moving up faster increases nausea severity without improving weight loss outcomes.
Semaglutide is a synthetic GLP-1 receptor agonist peptide — engineered to mimic glucagon-like peptide-1, the gut hormone that signals satiety and slows gastric emptying. Its dosing structure reflects how long receptor sensitivity takes to calibrate at each concentration before meaningful appetite suppression occurs.
Dose progression by week: the four-week hold pattern prevents the GI system overload that causes early dropout.
When a Slower Ramp Makes More Sense
Staying at an intermediate dose for 8 weeks instead of 4 is clinically common and does not compromise long-term results. If you're still managing moderate nausea at week 3 of a new dose level, holding another four weeks before advancing is the better option. Side effects at each stage are dose-dependent and generally predictable. For a breakdown by tier, semaglutide side effects by dose and timeline walks through what to expect at each escalation level.
What's the Difference Between Starting Dose and Maintenance on the Semaglutide Chart?
The 0.25mg starting dose is a tolerance calibration dose — not a therapeutic dose. Zero meaningful weight loss is expected at 0.25mg. Therapeutic effect begins around 0.5–1.0mg and intensifies through 2.4mg. The first 4–8 weeks are a necessary ramp, not a slow-onset weight loss phase.
| Parameter | Starting Dose | Maintenance Dose |
|---|---|---|
| Dose range | 0.25–0.50 mg | 1.0–2.4 mg |
| Weight loss effect | Minimal to none | Significant |
| GI side effects | Minimal | Moderate (adapts over time) |
| Time to reach | Week 1 | Weeks 9–21 |
| Primary purpose | GI tolerance building | Therapeutic weight loss |
Starting dose (0.25mg) builds tolerance; maintenance (1.0–2.4mg) delivers the actual weight loss effect.
Users searching "semaglutide not working" at week 2–4 are nearly always still on the tolerance dose. The protocol is functioning exactly as designed.
How Much Semaglutide Should You Take Each Week?
Weekly dose is determined by your position in the titration schedule — not by bodyweight. A 200lb and a 350lb user both begin at 0.25mg. The escalation timeline is standardized because receptor sensitivity, not body mass, governs the dose-response relationship for GLP-1 agonists.
Oral semaglutide (Rybelsus) follows a separate schedule: 3mg daily for 30 days, escalating to 7mg, then 14mg. Subcutaneous and oral routes are not dose-equivalent — the numbers reflect different bioavailability, not equivalent potency.
For compounded semaglutide, dose calculation is: Desired dose (mg) ÷ Vial concentration (mg/mL) = Volume (mL). Multiply by 100 for U-100 syringe units. A 0.5mg dose from a 5 mg/mL vial requires 10 units; the same 0.5mg from a 2.5 mg/mL vial requires 20 units.
When Do You Move to the Next Semaglutide Dosage Level?
Advance after a minimum four-week hold at your current dose, provided it's tolerated without severe GI symptoms. There is no clinical benefit to escalating faster — the metabolic and appetite-suppressing response at each dose level is established within those four weeks regardless.
Signs you're ready to advance:
- Nausea resolved or reduced to mild by week 3–4 of the current dose
- No severe GI events (vomiting, persistent fatigue, significant dizziness)
- Appetite suppression has stabilized or plateaued at current level
Signs to extend your hold:
- Persistent moderate-to-severe nausea past week 3
- Fatigue or sleep disruption still present at the current level
- Goal weight is close — the next escalation tier may be unnecessary
Quick win: Most semaglutide discontinuations happen in the first six weeks — not because the drug isn't working, but because side effects weren't managed. Holding at a dose for 8 weeks instead of 4 is consistently associated with better long-term adherence than rushing to the next tier.
Can You Adjust Your Semaglutide Dosage if You're Not Seeing Results?
Yes, in collaboration with your healthcare provider. If you've been at 1.0–1.7mg for 12 or more weeks without a weight response, escalating to the next tier is clinically reasonable. Most non-responders at 1.0mg do respond at 1.7–2.4mg — the ceiling dose was designed for exactly this group.
Before adjusting dose, rule out these variables:
- Dietary pattern: high-fat foods worsen gastric slowing and can blunt semaglutide's appetite suppression signal
- Alcohol consumption: even moderate drinking reduces GLP-1 drug efficacy and amplifies GI side effects — semaglutide and alcohol covers the interaction and what to adjust
- Injection site rotation: repeated dosing into the same location causes lipohypertrophy, reducing absorption consistency over time
Higher doses also have implications for lean tissue. For users concerned about body composition changes alongside dose escalation, semaglutide and muscle loss covers what the data shows and which metrics to log.
What Happens If You Exceed the Recommended Semaglutide Dosage?
Going above the 2.4mg weekly ceiling produces no additional weight loss and significantly increases adverse effect burden. Research confirms the GLP-1 receptor dose-response curve plateaus well before the 2.4mg ceiling. Higher doses increase nausea, vomiting, and pancreatitis risk without improving outcomes.
Reality check: Users reporting exceptional results from doses above 2.4mg are almost always miscalculating their concentration. A 10 mg/mL vial at 24 units delivers 2.4mg — but the same 24 units from a 2.5 mg/mL vial delivers 0.6mg. That's a fourfold difference. Concentration verification isn't optional; it's the entire calculation.
The most dangerous overdose scenario in compounded semaglutide isn't intentional — it's a unit-to-concentration conversion error. Always verify the mg/mL printed on your vial before drawing.
Logging each dose against your titration schedule in PeptideIQ eliminates concentration miscalculations and flags missed phase transitions.
How to Adjust Your Semaglutide Dosage Chart in PeptideIQ
Managing a 20-week titration across changing concentrations — with mid-protocol dose adjustments, side effects logged per dose level, and phase transitions to track — is exactly the systematic problem a protocol app solves.
PeptideIQ's Cycle Planner lets you configure your full semaglutide escalation schedule from day one. Set your starting dose at 0.25mg, build escalation phases (Phase 1: weeks 1–4 at 0.25mg, Phase 2: weeks 5–8 at 0.5mg), and receive automatic notifications when each phase transition is due. The app updates your scheduled dose at each transition — no recalculating, no spreadsheet edits.
When logging each injection, the reconstitution calculator confirms your exact syringe units based on your vial's actual concentration. Running a 5 mg/mL vial at 0.5mg? The app shows 10 units, not 20.

Frequently Asked Questions
What is the starting dose of semaglutide?
The standard starting dose for subcutaneous semaglutide is 0.25mg once weekly, maintained for four weeks before the first escalation. This dose is a tolerance calibration period — not a therapeutic dose. Oral semaglutide (Rybelsus) starts at 3mg daily, reflecting the lower oral bioavailability of the formulation.
How long does it take to reach maintenance semaglutide dose?
Reaching the 2.4mg weekly maintenance dose takes approximately 16–20 weeks on the standard four-week hold-and-increase protocol. Reaching the 1.0mg intermediate dose takes 8–12 weeks. Individual timelines vary — users who extend their hold periods due to side effects may take longer.
Can you stay at a lower semaglutide dose permanently?
Yes. If 0.5mg or 1.0mg produces adequate results with good tolerability, there is no clinical requirement to escalate further. The dose chart shows the maximum approved range, not a required endpoint. Dose ceilings exist for non-responders, not as targets everyone must reach.
What is the semaglutide dose difference between weight loss and diabetes use?
For Type 2 diabetes management (Ozempic), the approved maintenance range is 0.5mg–1.0mg weekly. For chronic weight management (Wegovy), the target maintenance dose is 2.4mg weekly. Both protocols start at 0.25mg with the same four-week escalation structure — the difference is in the ceiling and clinical indication, not the starting approach.
How does semaglutide dosing compare to tirzepatide?
Tirzepatide starts at 2.5mg weekly and escalates to a 15mg ceiling — higher absolute numbers that reflect its dual GLP-1/GIP receptor mechanism and distinct potency curve. The two compounds are not dose-equivalent and use separate titration charts. A protocol-level comparison of both escalation schedules is in tirzepatide dosing for weight loss.
