Key Takeaways

• Start at 0.25 mg weekly for 4 weeks, then increase by 0.25 mg or 0.5 mg increments every 4 weeks based on tolerance.
• The standard target maintenance dose for weight loss is 2.0 to 2.4 mg weekly, though many patients see strong results at 1.0 to 1.5 mg.
• Compounded vials allow custom doses (e.g., 0.375 mg, 0.75 mg, 1.25 mg) that brand-name pens cannot deliver.
• Rushing the dose escalation is the most common cause of severe GI side effects. Patience pays off.
• Vial concentrations vary (typically 1 mg/mL to 5 mg/mL), so reading your vial label carefully is essential for accurate dosing.
• Form Blends provides individualized dosing protocols with regular check-ins to optimize your response.

Overview: Why Dose Escalation Matters

Semaglutide is not a medication you start at full strength. The gradual dose increase serves two critical purposes:

1. GI tolerance. Your digestive system needs time to adjust to slowed gastric emptying. Starting at a full therapeutic dose would cause severe nausea, vomiting, and diarrhea in most patients.
2. Receptor sensitization. GLP-1 receptors in the brain and gut gradually become more responsive to semaglutide over weeks. A lower starting dose allows your body to develop the appetite-suppressing response smoothly.

Patients who try to accelerate the schedule or start at higher doses almost universally regret it. The GI side effects at too-high doses can be severe enough to cause dehydration, emergency room visits, and ultimately treatment discontinuation. The slow approach produces better adherence and better long-term results .

Standard Dosing Schedule

This schedule mirrors the Wegovy escalation protocol. Your provider may modify it based on your individual response, tolerance, and goals.

Custom Dosing: The Compounded Advantage

One of the primary benefits of compounded semaglutide is the ability to dial in custom doses that brand-name products do not offer. Brand-name Ozempic comes in fixed doses of 0.25 mg, 0.5 mg, 1.0 mg, and 2.0 mg. Wegovy offers 0.25 mg, 0.5 mg, 1.0 mg, 1.7 mg, and 2.4 mg. There are no in-between options.

With compounded semaglutide from a vial, your provider can prescribe any dose by adjusting the injection volume. Common custom doses include:

• 0.375 mg: A midpoint between 0.25 mg and 0.5 mg for patients who experience significant nausea at 0.5 mg.
• 0.75 mg: An intermediate step between 0.5 mg and 1.0 mg for patients who need a slower escalation.
• 1.25 mg: A gentle step up from 1.0 mg rather than jumping to 1.5 mg or 1.7 mg.
• 1.75 mg: A bridge dose between 1.5 mg and 2.0 mg.

This granularity allows providers to keep patients progressing while minimizing the side effect spikes that often accompany the larger jumps in brand-name escalation schedules.

Understanding Vial Concentrations

Compounded semaglutide comes in multi-dose vials at various concentrations. Understanding your vial's concentration is essential for drawing the correct dose.

Important notes:

• Standard insulin syringes are marked in "units" where 100 units = 1 mL.
• Higher concentration vials require smaller injection volumes, which can be more comfortable but demand more precision when drawing up.
• Always verify your vial's concentration on the label before drawing your dose. If you receive a new vial with a different concentration, recalculate your injection volume.
• When in doubt, contact your provider or pharmacist. Dosing errors with concentrated vials can mean receiving 2 to 5 times the intended dose.

How to Draw and Inject Your Dose

1. Wash your hands thoroughly with soap and water.
2. Check your vial. Verify the concentration on the label. The solution should be clear and colorless. Do not use if cloudy, discolored, or containing particles.
3. Clean the vial top with an alcohol swab. Let it dry.
4. Draw up your dose. Using an insulin syringe, pull back the plunger to the correct volume for your prescribed dose. Insert the needle into the vial, push air in, then invert the vial and slowly draw out the medication.
5. Remove air bubbles. Tap the syringe gently to move bubbles to the top, then push the plunger slightly to expel them.
6. Choose your injection site. Abdomen (2+ inches from navel), thigh (front or outer), or upper arm (back). Rotate sites each week.
7. Clean the injection site with an alcohol swab. Let it dry completely.
8. Pinch the skin, insert the needle at a 45 to 90 degree angle, and push the plunger steadily.
9. Hold for 5 to 10 seconds after fully depressing the plunger before withdrawing the needle.
10. Do not rub the injection site. Apply gentle pressure with a cotton ball if needed.
11. Dispose of the syringe in a sharps container.

When to Increase, Pause, or Decrease Your Dose

Signs It Is Time to Increase

• You have been at your current dose for at least 4 weeks
• GI side effects have resolved or are minimal
• Appetite suppression is wearing off before the next injection day
• Weight loss has stalled for 3+ weeks despite consistent diet and exercise

Signs to Pause at Your Current Dose

• You are still experiencing moderate nausea or GI effects
• Weight loss is steady (1 to 2 lbs/week) at your current dose
• You feel good and do not need stronger appetite suppression

Signs to Decrease or Hold

• Severe nausea or vomiting lasting more than 3 days
• Unable to eat or stay hydrated
• Losing weight too rapidly (more than 3 lbs/week consistently)
• Significant fatigue, dizziness, or weakness

Your provider should be making these decisions with you, not leaving you to guess. Regular check-ins (at minimum monthly) ensure your dose matches your body's current needs.

Storage and Handling

• Unopened vials: Refrigerate at 36 to 46 degrees F (2 to 8 degrees C). Do not freeze.
• Opened (in-use) vials: Refrigerate between uses. Most compounded semaglutide has a beyond-use date of 28 to 90 days after compounding, printed on the label.
• Temperature excursions: Brief exposure to room temperature (during injection) is fine. Avoid leaving vials in hot cars, direct sunlight, or near heat sources.
• Syringes: Store unused syringes at room temperature in their sterile packaging. Never reuse syringes.
• Travel: Use an insulated bag with a cold pack when traveling. TSA allows insulin syringes and medication vials with proper labeling.

Dosing Mistakes and How to Handle Them

Frequently Asked Questions

What dose of compounded semaglutide is most effective for weight loss?

Most patients see the strongest weight loss at 1.0 to 2.4 mg weekly. The STEP 1 trial showed that 2.4 mg weekly produced an average of 14.9% body weight loss over 68 weeks. However, some patients achieve excellent results at lower doses. Your provider will help determine the lowest effective dose for your goals.

Can I stay on a lower dose if it is working?

Absolutely. If you are losing weight steadily and tolerating a lower dose well, there is no requirement to escalate to the maximum. Some patients maintain on 1.0 mg or 1.5 mg indefinitely with excellent results.

How do I know if my dose is too high?

Persistent nausea lasting more than 2 weeks, inability to eat adequate protein, severe fatigue, or losing weight faster than 3 pounds per week consistently may indicate your dose is too high. Contact your provider to discuss a reduction.

What if I want to increase my dose faster?

We strongly advise against accelerating the escalation schedule. Faster escalation leads to more severe side effects, higher dropout rates, and no better long-term weight loss. Trust the gradual approach.

Is the dosing the same as Ozempic or Wegovy?

The milligram amounts are the same, and the general escalation principle is the same. The main difference is that compounded semaglutide allows for intermediate doses that brand-name pens cannot deliver, giving your provider more flexibility to customize your escalation.

How long will one vial last?

This depends on the vial size, concentration, and your dose. A typical 2 mL vial at 2.5 mg/mL contains 5 mg total, which lasts 20 weeks at the 0.25 mg starting dose but only 2.5 weeks at the 2.0 mg dose. Your pharmacy should provide enough medication to cover your prescribed dose for the dispensing period (usually 4 to 8 weeks).
