All formulations include B12 (methylcobalamin) for energy support.

GLP-1 (Semaglutide) medications are designed to work like a natural hormone in your body that regulates appetite and blood sugar. GLP-1 mimics one hormone that can help you feel satisfied longer, slow digestion, and curb hunger to support weight management for some people when used with provider guidance and healthy habits.

GLP-1 + GIP (Tirzepatide) mimics two hormones and may lead to greater weight loss, stronger blood sugar improvements, and greater appetite suppression.

Potential Benefits

  • Decreases appetite and reduces cravings

  • Promotes weight loss

  • Lowers A1C levels (a marker of blood sugar control)

  • Improves cardiometabolic health measures

  • Enhances insulin sensitivity

  • Reduces Inflammation

  • GLP-1+B12: Semaglutide, Methylcobalamin (concentration varies)

    GLP-1+GIP+B12: Tirzepatide, Methylcobalamin (concentration varies)

    30 or 90 day supply options; Includes subcutaneous injection needles

    If approved, appropriate dose will be determined by a licensed healthcare provider during your complimentary online exam.

  • Medication is designed for absorption into the bloodstream via injection, to allow systemic delivery without passing through the GI tract. Individual absorption may vary.

    Injection: Subcutaneous injection into the fat with a small needle. Includes subcutaneous injection needles.

    GLP-1 medications act on areas of the brain and digestive system to:
    • Reduce appetite and cravings
    • Slow digestion so you feel full longer
    • Improve blood sugar control

    GLP-1 (Semaglutide) is a single-action therapy that mimics one hormone:

    GLP-1 (glucagon-like peptide-1):
    • Reduces appetite and cravings
    • Slows digestion so you feel full longer
    • Improves blood sugar control

    GIP/GLP-1 (Tirzepatide) is a dual-action therapy that mimics two hormones:

    GLP-1 (glucagon-like peptide-1):
    • Reduces appetite and cravings
    • Slows digestion so you feel full longer
    • Improves blood sugar control

    GIP (glucose-dependent insulinotropic polypeptide):
    • Further supports insulin response
    • May enhance fat metabolism and appetite control

    Because it targets two pathways instead of one, tirzepatide may lead to greater weight changes, stronger blood sugar improvements, and more appetite suppression for some people.

  • What are GLP-1 medications?
    GLP-1 medications are prescription therapies that mimic natural hormones involved in appetite and blood sugar regulation. They help you feel fuller longer, reduce cravings, and support healthier eating patterns as part of a provider-guided wellness plan.

    What are GLP-1 medications used for?
    They’re commonly used to support weight management and metabolic health when combined with lifestyle changes like nutrition, movement, and sleep.

    How do GLP-1s work in the body?
    GLP-1s act on areas of the brain and digestive system to:
    • Reduce appetite and cravings
    • Slow digestion so you feel full longer
    • Improve blood sugar control

    How long does it take to see results?
    Benefits like appetite reduction and weight changes may be noticed within a few weeks, but individual responses vary based on dose, consistency, and personal biology.

    Can I use this with other medications?
    GLP-1s can be used with many medications, but they should NOT be used with other GLP-1 therapies. Always tell your provider about all medications and supplements you’re taking so they can review for interactions.

    How does a GLP-1 (Semaglutide) differ from a GIP/GLP-1 (Tirzepatide)?
    GLP-1 (Semaglutide) is a single-action therapy that mimics one hormone:

    GLP-1 (glucagon-like peptide-1):
    • Reduces appetite and cravings
    • Slows digestion so you feel full longer
    • Improves blood sugar control

    GIP/GLP-1 (Tirzepatide) is a dual-action therapy that mimics two hormones:

    GLP-1 (glucagon-like peptide-1):
    • Reduces appetite and cravings
    • Slows digestion so you feel full longer
    • Improves blood sugar control

    GIP (glucose-dependent insulinotropic polypeptide):
    • Further supports insulin response
    • May enhance fat metabolism and appetite control

    Because it targets two pathways instead of one, tirzepatide may lead to greater weight changes, stronger blood sugar improvements, and more appetite suppression for some people.

    Why does it include vitamin B12?
    Methylcobalamin (vitamin B12) is added to help provide energy support.

    What if I miss an injection?
    If you miss a dose, contact your healthcare provider for guidance on how to safely get back on schedule.

    How is GLP-1 taken?
    GLP-1 medications are typically taken as a once-weekly injection under provider guidance. Daily sublingual options are also available.

    Are there side effects?
    Please refer to the medication information linked on this page.

    Who should NOT use GLP-1?
    Please refer to the medication information linked on this page. Make sure to discuss your current medications and health history with your provider to see if this medication is appropriate for you.

    How long will I stay on a GLP-1?
    There’s no one-size-fits-all timeline. Your provider will monitor your progress and adjust your plan over time based on your goals and response.

    Is GLP-1 FDA-approved?
    Brand-name versions of semaglutide and tirzepatide are FDA-approved for certain indications. Compounded versions are prescribed by licensed providers and dispensed by state-licensed pharmacies in accordance with regulations.
