Compounded Semaglutide Dosage Chart & Guide
Compounded semaglutide offers significant cost savings compared to brand Ozempic or Wegovy but requires understanding proper dosing, titration schedules, and vial concentrations. This comprehensive guide provides dosage charts, syringe conversion tables, and safety information for safe, accurate self-administration of compounded semaglutide.
Understanding Compounded Semaglutide Dosing Fundamentals
Compounded semaglutide is prepared by licensed pharmacy compounding using bulk semaglutide powder mixed with sterile solutions to create injectable medications. The semaglutide molecule itself is identical to brand medications—it's a synthetic GLP-1 receptor agonist—but the preparation process differs from commercial manufacturing.
Unlike brand Ozempic or Wegovy delivered in convenient pre-filled pens, compounded semaglutide arrives as a vial containing a specific concentration (typically 1mg/mL, 2.5mg/mL, or 5mg/mL) that you must measure and inject yourself using an insulin syringe.
Understanding your vial's concentration is critical because it determines the volume you must inject to deliver the correct dose. A vial labeled "1mg/mL" means the solution contains 1 milligram of semaglutide per 1 milliliter of liquid. A 0.25mg dose requires 0.25mL of this solution.
The pharmacologic effects of compounded semaglutide are identical to brand medications when doses are equal. A 1mg injection of compounded semaglutide produces the same weight loss, diabetes control, and side effects as 1mg of brand Ozempic. The cost difference ($200-400/month for compounded vs $1,200-1,500/month for brand) is the primary advantage, though you sacrifice FDA oversight of the finished product.
Standard Semaglutide Titration Schedule
The standard titration schedule for compounded semaglutide mirrors the FDA-approved schedule used for Ozempic and Wegovy. This gradual increase in doses allows your body to adapt, minimizing nausea and gastrointestinal side effects.
Week 1-4: 0.25mg once weekly via subcutaneous injection. This is the starting dose for all patients regardless of body weight or treatment indication. Most patients tolerate 0.25mg well with minimal side effects.
Week 5-8: 0.5mg once weekly. After 4 weeks on 0.25mg, increase to 0.5mg. This dose intensifies appetite suppression and weight loss.
Week 9-12: 1mg once weekly. Most patients begin experiencing significant weight loss by this dose. Nausea and gastrointestinal side effects are most common at this transition.
Week 13+: 1.7mg or 2.4mg weekly based on treatment goals and tolerance. These are the maintenance doses. Some patients achieve adequate weight loss at 1mg and remain there. Others progress to 1.7mg for enhanced effect. The maximum approved dose is 2.4mg weekly, though research suggests 2.4mg is optimal for weight loss.
This standard schedule assumes 4-week intervals between dose increases. Some patients titrate faster (every 2-3 weeks) or slower (every 6-8 weeks) based on individual tolerance. Discuss your titration pace with your prescribing provider.
Compounded Semaglutide Dosage Chart
The following chart shows the standard dosing schedule with recommended volumes for common concentrations:
| Week | Dose (mg) | Volume @ 1mg/mL | Volume @ 2.5mg/mL | Volume @ 5mg/mL | Frequency |
|---|---|---|---|---|---|
| 1-4 | 0.25 | 0.25 mL | 0.1 mL | 0.05 mL | Once weekly |
| 5-8 | 0.5 | 0.5 mL | 0.2 mL | 0.1 mL | Once weekly |
| 9-12 | 1.0 | 1.0 mL | 0.4 mL | 0.2 mL | Once weekly |
| 13-16 | 1.7 | 1.7 mL | 0.68 mL | 0.34 mL | Once weekly |
| 17+ | 2.4 | 2.4 mL | 0.96 mL | 0.48 mL | Once weekly |
Syringe Unit Conversions for Accurate Dosing
Standard insulin syringes measure in units (U), where 100 units = 1 mL. Converting your semaglutide dose to syringe units ensures accurate dosing with standard injection equipment.
For 1mg/mL concentration: This is the most straightforward concentration. One unit on an insulin syringe equals 0.01mL, which delivers 0.01mg of semaglutide. Therefore: 0.25mg = 2.5 units. 0.5mg = 5 units. 1mg = 10 units. 1.7mg = 17 units. 2.4mg = 24 units. You can clearly see these doses on standard insulin syringe markings.
For 2.5mg/mL concentration: This concentration allows smaller injection volumes but requires more precise measuring. 0.25mg = 1 unit (0.01mL). 0.5mg = 2 units (0.02mL). 1mg = 4 units (0.04mL). 1.7mg = 6.8 units (0.068mL). 2.4mg = 9.6 units (0.096mL). Note that 1.7mg and 2.4mg doses require marking between standard unit lines.
For 5mg/mL concentration: This highest concentration requires the smallest volumes, which can be challenging to measure accurately. 0.25mg = 0.5 units (0.005mL). 0.5mg = 1 unit (0.01mL). 1mg = 2 units (0.02mL). 1.7mg = 3.4 units (0.034mL). 2.4mg = 4.8 units (0.048mL). These very small volumes are difficult to measure precisely with standard syringes.
Most compounding pharmacies recommend 1mg/mL concentration for ease of accurate dosing. The volumes are large enough to measure easily, and the unit conversions are straightforward. However, if your pharmacy provides 2.5mg/mL or 5mg/mL, ask them for a printed conversion chart showing your specific units and volumes.
How Compounded Semaglutide Concentrations Affect Dosing
The concentration of semaglutide in your vial determines the volume you must inject to deliver the intended dose. Understanding this relationship is fundamental to safe dosing.
A concentration describes how many milligrams of active semaglutide are contained in each milliliter of solution. A vial labeled "1mg/mL" contains 1mg semaglutide per 1mL of liquid. A vial labeled "2.5mg/mL" contains 2.5mg per 1mL of liquid.
For a given dose, higher concentrations require smaller volumes. To deliver a 0.25mg dose: from 1mg/mL vial, you need 0.25mL. From 2.5mg/mL vial, you need 0.1mL (one-tenth the volume). From 5mg/mL vial, you need 0.05mL (one-twentieth the volume).
While smaller volumes might seem preferable, measuring 0.05mL accurately with a standard insulin syringe is challenging. The markings on insulin syringes are graduated in 1-unit increments (0.01mL), making very small volumes prone to measuring errors. A measurement error of just one unit significantly alters the dose delivered.
This is why most compounding pharmacies default to 1mg/mL concentration. It provides a practical balance: volumes are large enough to measure accurately (0.25mL to 2.4mL) without requiring specialized equipment.
Before ordering from a compounding pharmacy, ask what concentrations they offer and which they recommend for your dosing schedule. Confirm the concentration on your vial label matches what you ordered, as dosing errors from concentration confusion can lead to under- or overdosing.
Injection Technique for Compounded Semaglutide
Compounded semaglutide is administered as a subcutaneous injection—injecting under the skin rather than into muscle or vein. Standard injection sites include the abdomen (avoid the area 2 inches around the belly button), thigh, or upper arm.
Before injecting, check the vial. Semaglutide solution should be clear and colorless. If the solution is cloudy, discolored, has particles, or appears abnormal, do not inject. A cloudy appearance may indicate contamination or degradation. Contact your pharmacy for replacement.
Allow refrigerated vials to reach room temperature for 5-10 minutes before injecting. Cold injections are uncomfortable. Draw your measured dose into a clean insulin syringe using sterile technique. Pinch the injection site skin to create a fold, insert the needle at a 45-90 degree angle, and depress the plunger smoothly. After injection, maintain pressure on the site for 5-10 seconds to minimize bleeding. Rotate injection sites to prevent lipohypertrophy (thickened fat deposits).
Each vial is for single-patient use only. Do not share vials between patients. Store used needles in a sharps container. Consult your pharmacy or healthcare provider for proper sharps disposal in your area.
Comparing Compounded to Brand Semaglutide Dosing
The semaglutide molecule in compounded preparations is chemically identical to brand Ozempic and Wegovy. The pharmacologic effects and dose requirements are therefore identical. A 1mg injection of compounded semaglutide produces the same glucose-lowering and weight loss effects as 1mg of brand Ozempic.
However, the delivery systems differ dramatically. Brand Ozempic and Wegovy are delivered via easy-to-use pre-filled pens. You simply dial the dose, inject, and the pen automatically measures the correct volume. Compounded semaglutide requires manual measurement and injection.
The practical implication is that compounded semaglutide requires more patient responsibility and has higher risk of measurement errors. If you're uncomfortable with injections, syringes, and precise measurement, brand medications may be worth the higher cost for convenience and safety.
However, if you're experienced with insulin injections or comfortable learning proper technique, compounded semaglutide offers identical pharmacologic effects at a fraction of the cost.
Dose Adjustments and Maintenance Dosing
After reaching your target dose (typically 1-2.4mg weekly), you'll maintain that dose weekly for the duration of treatment. Most patients find that 1.7mg or 2.4mg provides optimal weight loss. Some patients achieve adequate results at lower doses and choose to remain there.
If side effects become intolerable at any dose, discuss with your provider. You may benefit from slowing titration (remaining at each dose level longer than 4 weeks), stepping back to a previous dose level, or discontinuing the medication. Nausea and gastrointestinal effects usually improve after 4 weeks on a given dose, so temporary side effects don't necessarily warrant dose reduction.
As you lose weight, your semaglutide dose typically remains unchanged. Weight loss alone doesn't require dose adjustment. However, if you plateau on weight loss despite adequate doses, your provider might discuss increasing to the next dose level or trying alternative medications.
Upon stopping semaglutide, there's no taper required. You can discontinue any dose abruptly without withdrawal effects. However, weight regain often occurs after discontinuation, so discuss long-term maintenance with your provider before stopping.
Safety and Quality Considerations
Compounded semaglutide lacks FDA approval for the finished product, meaning quality assurance varies between compounding pharmacies. This is the key tradeoff for the cost savings: you accept lower regulatory oversight.
Select a reputable compounding pharmacy with Pharmacy Compounding Accreditation Board (PCAB) certification. PCAB certification indicates the pharmacy meets stringent quality standards. Ask if the pharmacy uses pharmaceutical-grade semaglutide powder from FDA-approved bulk suppliers. Some compounders use lower-quality or uncertified bulk powder, increasing contamination or potency variation risks.
Request certificates of analysis (COAs) from your pharmacy, showing potency testing confirming the vial contains the labeled concentration. Reputable compounders test each batch and provide documentation.
Inspect vials upon arrival. The solution should be clear and colorless. Cloudiness, discoloration, or particles indicate contamination. Damaged vials or unexpectedly short expiration dates warrant replacement.
Report any adverse effects beyond expected side effects (severe allergic reactions, extreme nausea, injection site infections, or unusual symptoms) to your healthcare provider immediately.
Storage, Stability, and Handling
Proper storage is critical for maintaining semaglutide potency. All compounded semaglutide must be refrigerated at 36-46°F (2-8°C). A standard kitchen refrigerator is appropriate. Clearly label the vial with the date received and expiration date provided by the pharmacy.
Most compounded semaglutide vials remain stable for 28 days after opening if properly refrigerated. Some formulations may have different stability windows; always check the label. Do not store opened vials longer than directed.
Never freeze semaglutide. Freezing damages the semaglutide peptide molecule and destroys its activity. Thawing frozen semaglutide damages it further. If a vial freezes accidentally, discard it.
If a vial has been left unrefrigerated, estimate the duration. If unrefrigerated for less than 1 hour, it's likely safe. If unrefrigerated for more than a few hours, discard to be safe. During travel, transport vials in insulated cases with ice packs to maintain temperature.
Once you draw a dose into a syringe, inject immediately. Do not pre-draw syringes and store them, as this degrades semaglutide and increases contamination risk.

The standard compounded semaglutide titration schedule mirrors the FDA-approved Ozempic/Wegovy schedule: Week 1-4: 0.25mg once weekly. Week 5-8: 0.5mg once weekly. Week 9-12: 1mg once weekly. Week 13+: 1.7mg or 2.4mg once weekly based on tolerance and treatment goals. Each dose is administered as a subcutaneous injection once weekly. The titration spacing (4 weeks per dose level) allows your body to adjust to each dose, minimizing nausea and side effects. Some patients may titrate faster (every 2-3 weeks) or slower (every 6-8 weeks) based on individual tolerance.
Three common compounding concentrations exist: 1mg/mL concentration (1mg semaglutide per 1mL liquid) requires 0.25mL for 0.25mg dose. 2.5mg/mL concentration (2.5mg semaglutide per 1mL) requires 0.1mL for 0.25mg dose. 5mg/mL concentration (5mg semaglutide per 1mL) requires 0.05mL for 0.25mg dose. Higher concentrations require smaller injection volumes, which some patients prefer. However, smaller volumes can be harder to measure accurately with standard insulin syringes. Most compounding pharmacies default to 1mg/mL or 2.5mg/mL for optimal accuracy. Check your pharmacy's available concentrations before ordering.
Standard insulin syringes measure in units (100 units = 1mL). For 1mg/mL concentration: 0.25mg = 2.5 units, 0.5mg = 5 units, 1mg = 10 units, 1.7mg = 17 units, 2.4mg = 24 units. For 2.5mg/mL: 0.25mg = 1 unit, 0.5mg = 2 units, 1mg = 4 units, 1.7mg = 6.8 units, 2.4mg = 9.6 units. For 5mg/mL: 0.25mg = 0.5 units, 0.5mg = 1 unit, 1mg = 2 units, 1.7mg = 3.4 units, 2.4mg = 4.8 units. Always verify the concentration on your vial label and ask your pharmacy for specific unit conversion charts matching your concentration. Marking your syringe with tape at the correct fill line aids accurate dosing.
Compounded semaglutide and brand medications (Ozempic, Wegovy) contain identical semaglutide molecules, so pharmacologic effects are the same when dosed equally. The key differences are: (1) Compounded versions are not FDA-approved finished products but are state-regulated pharmacy preparations. (2) Brand medications undergo extensive FDA quality testing; compounded versions lack this oversight. (3) Cost differs dramatically: compounded $200-400/month vs brand $1,200-1,500/month. (4) Dosage forms differ: compounded comes in vials requiring self-injection; Ozempic/Wegovy come in convenient pre-filled pens. (5) Long-term safety data are more robust for brand versions. Compounded versions are cost-saving alternatives for uninsured patients but lack FDA quality assurance of brand medications.
Higher concentrations (5mg/mL) require smaller injection volumes, which some patients prefer psychologically. However, smaller volumes (0.05mL) are harder to measure accurately with standard insulin syringes, potentially leading to dosing errors. Most endocrinologists and compounding pharmacies recommend 1mg/mL or 2.5mg/mL concentrations for better accuracy. Insulin syringes graduated in 0.5-unit increments work well for these concentrations. Unless you have specific reasons preferring smaller volumes, stick with standard concentrations. Ask your pharmacy which concentration they recommend for your dosing needs and syringe accuracy.
Compounded semaglutide vials should be stored in the refrigerator at 36-46°F (2-8°C) unless otherwise directed by your pharmacy. Once opened, most compounded semaglutide remains stable for 28 days if refrigerated properly. Some formulations may have different stability windows; always check the label for specific expiration dates. Avoid freezing, as freezing damages the semaglutide molecule. Once a dose is drawn into a syringe, use immediately; do not store pre-drawn syringes. Keep vials away from direct light. During travel, use insulated cases with ice packs to maintain temperature. If a vial has been unrefrigerated for more than a few hours, discard it. Proper storage is critical for maintaining semaglutide potency.
