It's normal for your medication's color, label format, or the number of syringe units to change between shipments. These changes usually come from one of three sources: a switch between added vitamins (B6 vs. B12), a concentration change in the vial, or your order being fulfilled by a different pharmacy partner.

If the color changed: This reflects a change in the added vitamin, not the active medication. Tirzepatide with B6 appears clear or slightly yellow; semaglutide with B12 appears pink or red; our additive-free (Pure) formulations have no B-vitamin tint. All formulations are safe and effective.

If the units changed: Check the concentration on your new vial label (mg/mL). Your provider will update your instructions to match. Always confirm your dose in milligrams, not just units, before injecting.

If the label format or pharmacy name changed: Your order is routed based on your medication, any B-vitamin allergy you reported, and the state you live in. A different partner may use a different label format, vial size, or concentration. For details on who makes your medication, see Where does my medication come from?

Tirzepatide + B6: Vitamin B6 supports protein metabolism, mood regulation and immune function, and may help reduce nausea. The solution appears clear or slightly yellow.

Pure Tirzepatide: no added vitamin, so no tint — the solution is clear or near-colourless.

Semaglutide + B6: Vitamin B6 supports protein metabolism, mood regulation and immune function, and may help reduce nausea. The solution appears clear or slightly yellow.

Semaglutide + Glycine: Glycine is an amino acid, not a B vitamin, so it's a good option if you have a B-vitamin allergy or sensitivity. The solution is clear or near-colourless.

All formulations use the base form of the active ingredient, not a salt form, and are made by FDA-registered compounding pharmacies. The added vitamin (or amino acid) does not change your dose.
