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 (e.g., 10 mg/mL vs. 20 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: As of April 2026, Belle works with multiple pharmacy partners (The Pharmacy Hub/BPI Labs, Hallandale, Bourdeaux, and VialsRx). 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.
