Frequently asked questions
What makes B12/MIC different from regular B12?
B12/MIC provides the same great vitamin supplementation as B12 injections, but with a few added benefits. When combined with MIC, the metabolism-boosting principles of the injection are amplified, enhancing the body’s ability to break through weight loss stagnation.
How often do I administer B12/MIC injections?
Start by injecting 1ml/cc per injection up to 2 times per week or use as prescribed. We’re here to help. Contact our team to adjust your prescription.
Will I lose weight with B12/MIC Injections?
Every body is different. Depending on your weight loss goals, lifestyle choices, and any underlying medical conditions, the results you see on the scale may vary. B12/MIC should be used in combination with diet and exercise to maximize results.

The science of B12/MIC
Vitamin B12 supports cellular energy production, while Methionine, Inositol, and Choline (MIC) work together to balance insulin signaling and support metabolism, helping the body produce energy to use fat more efficiently.3 4 6 7
Unlike many weight loss medications that work by suppressing appetite signaling, B12/MIC is designed to address age-related metabolic slowdown, helping the body reduce fat while preserving muscle.2 3 8

Frequently asked questions
Most side effects of B12/MIC are generally mild in nature and dissipate within a short time frame following administration. Common side effects may include pain, redness, or itching at the injection site.
If irritation continues to occur, apply an over-the-counter itch cream, or talk to your AgelessRx provider if symptoms persist for several weeks or become intolerable.
All B12/MIC Injections are only available as intramuscular injections.
Subcutaneous injections deliver medication into the layer of tissue just below the skin, while intramuscular injections go one layer deeper, directly into the muscle.
Subcutaneous B12/MIC Injections may be associated with an increased risk for irritations and reactions at the injection site. As such, our pharmacy partners only provide standard intramuscular injections.
B12/MIC Injections are administered intramuscularly into the muscle tissue. Recommended injection sites include the outer thigh or the deltoid muscle of the upper arm. Rotating injection sites between doses may help reduce irritation at any single location.
B12/MIC Injections should be stored in a cool, dry place away from direct light. Refrigeration is recommended but not required. Do not freeze. Keep out of reach of children.
