What color should compounded semaglutide be?

What color should compounded semaglutide be?

Quick answer: There is no FDA-approved description for compounded semaglutide. Brand labels say semaglutide should be clear and colorless; ask your pharmacy what your vial should look like.

Use the dose on your label from your REMEVi provider; this page explains the units, it does not set your dose.

The only official descriptions of how semaglutide should look are on the brand labels. Novo Nordisk’s Wegovy® label (revised 06/2026) says: “Only use if the solution is clear, colorless, and contains no particles.” The Ozempic® label (revised 05/2026) says it “should appear clear and colorless.”

Compounded semaglutide and tirzepatide are prepared by licensed pharmacies for an individual prescription. They are not FDA-approved, and the FDA has not reviewed them for safety, effectiveness or quality. That means no FDA-approved label describes how a compounded vial should look. The pharmacy that prepared it is the source for that, and some compounded products contain added ingredients, as the next sections explain.

What do the brand labels say the liquid should look like?

Quick answer: Wegovy® and Ozempic®: clear and colorless. Zepbound® and Mounjaro®: clear and colorless to slightly yellow. None should have particles.

Each manufacturer’s label tells you what its product should look like and when not to use it. Ozempic®’s pen instructions add a plain test: look through the pen window, and if the medicine “looks cloudy or contains particles, do not use the pen.” With a vial you can see all of the liquid before you draw, which makes the same check easy.

Wegovy®, Ozempic®, Zepbound® and Mounjaro® are FDA-approved brand-name products that REMEVi does not sell. Facts quoted from their labels describe those products only. We name them to orient you, not to suggest a compounded medication is equivalent to them.

Is it normal for tirzepatide to look slightly yellow?

Quick answer: Lilly’s tirzepatide labels describe the liquid as “clear and colorless to slightly yellow.” That describes the brand products; ask your pharmacy about a compounded vial.

For Zepbound® and Mounjaro®, a slight yellow tint is within the label description (Zepbound label, revised 08/2026; Mounjaro label, revised 08/2026). Lilly’s vial instructions turn that into a checklist before each dose: the medicine is not frozen, is colorless to slightly yellow, is not cloudy and does not have particles.

That checklist is a good habit for any vial. But whether a slight tint is expected in your compounded tirzepatide is a question for the pharmacy that made it, not something a brand label can answer.

Why might a compounded vial look different?

Quick answer: The FDA notes some compounders add ingredients such as vitamin B12, B6, L-carnitine or NAD. The FDA does not describe how those change the color.

In a footnote to its July 26, 2024 alert, the FDA says it “is aware that some compounders incorporate additional ingredients, such as cyanocobalamin (Vitamin B-12), pyridoxine (Vitamin B-6), levocarnitine (L-Carnitine) and nicotinamide adenine dinucleotide (NAD), into their semaglutide products. The safety and effectiveness of combining semaglutide with other ingredients has not been established.”

You may read online that one of these additives gives a vial a particular color. We don’t repeat that here: neither the FDA pages nor the USP guidance we checked describes a color for these mixtures. Your vial label should list what is in it. If it lists an added ingredient, ask the pharmacy what the vial should look like before you use it. Added ingredients matter for another reason too: they change what you are injecting, and the FDA says the safety and effectiveness of those combinations has not been established. If you expected a semaglutide-only vial and the label lists something else, call — even if the color looks normal.

When should I not use a vial?

Quick answer: Don’t use it if it is cloudy, has particles, looks discolored, was frozen, arrived warm, or looks different from your last vial. Call first.

Each of these comes from a label or from the FDA:

• Cloudy or with particles — every brand label above (Ozempic, Zepbound vial).
• Discolored — the Zepbound® and Mounjaro® labels say not to use it if discoloration is seen (Lilly).
• Frozen — brand labels say not to use it if it has been frozen (Wegovy).
• Arrived warm — the FDA advises not using an injectable GLP-1 that arrives warm or with insufficient refrigeration (FDA).
• Different from before — the FDA lists medicine “that looks different than what you’ve previously received” as a red flag (FDA).

When in doubt, wait for an answer. A day’s delay while you check is a small thing next to injecting from a vial you are unsure about.

How long compounded semaglutide can stay out of the fridge

What should I do if my vial looks wrong?

Quick answer: Don’t inject from it. Keep the vial and its packaging, have the label in hand, and call your REMEVi care team or the pharmacy.

The FDA’s list of warning signs from online sellers (October 1, 2026) includes medicine that “looks different than what you’ve previously received … or was pictured on their website,” and packaging that “is broken or damaged or lacks instructions for use.” Any of those is a reason to stop and call before the next dose.

Take a photo of the vial in good light, next to the label, before you call — it makes the conversation faster. Don’t throw the vial away until the care team or pharmacy tells you to.
