Alternate dosage forms are compounded only where a licensed clinician documents a patient-specific clinical need that a commercially available product cannot meet. They are not interchangeable with, and are not substitutes for, FDA-approved products. Compounded medications are not FDA-approved and have not been evaluated by the FDA for safety, efficacy, or quality.

Boxed warning

FDA-approved semaglutide products carry a boxed warning concerning thyroid C-cell tumors observed in rodents. That warning is why a personal or family history of medullary thyroid carcinoma or MEN 2 is a contraindication.

A licensed clinician reviews your health history and medications and determines whether treatment is appropriate for you.

What It Is

A lower dose is still an individual decision.

This compounded injection combines semaglutide and vitamin B12. “Microdose” is the name used for this lower-dose option; it is not a standardized FDA-approved GLP-1 dosing category.

Your clinician considers your treatment history, response, tolerability and the medical reason for the combination. The prescribed dose comes from that evaluation, not from the product name or an online dosing chart.

Vitamin B12 is an essential nutrient. Adding it does not establish greater weight loss or fewer side effects, and a lower dose does not guarantee the results reported for approved medicines.

Your plan includes clinical review, prescribed medication, pharmacy fulfillment, shipping and care-team messaging. This compounded preparation is not FDA-approved.

Who It's For

For the case where individualization has a clinical reason.

01

The Sensitive Responder

Prior medication tolerability is part of your medical history, not a personality trait. You want the formulation decision made with that history in view rather than assuming the standard path fits everyone.

02

The Individualized Case

A clinician has a specific reason to consider a compounded combination rather than a standard finished product. The reason comes from the case, not from a preference for “microdosing.”

03

The Holding Pattern

During care, a provider may determine that a reduced-dose phase fits the patient's current clinical picture. The dose is set by the provider and is not an entry point selected at signup.

This lower-dose compounded preparation is not FDA-approved. Your clinician evaluates the individual need for the formulation; lower dosing does not guarantee fewer side effects.

This might not be the right fit if:
  • Personal or family history of medullary thyroid carcinoma or MEN 2
  • History of pancreatitis
  • Pregnancy, planned pregnancy, or breastfeeding
  • Hypersensitivity to cobalt or vitamin B12

Your intake screens for all contraindications. Every candidate is evaluated by a licensed clinician before any prescription is issued. No prescription is issued without clearance.

Care and cost

Clear pricing. Care that follows through.

Your plan brings the clinical review, prescribed medication, pharmacy fulfillment, shipping and care-team messaging together. The consultation is included in your plan price.

What will I pay at the start and on renewal?
$129 billed monthly, or $327 paid up front every three months ($109/month equivalent; three-month commitment). These are the standard recurring prices, before any eligible first-order discount. The monthly equivalent is not a monthly charge.
Does a dose change affect the price?
The displayed price is for the Semaglutide + B12 Microdose plan and selected billing interval. Confirm the prescribed strength, quantity and price before starting or changing treatment. Moving to a different product or formulation can change the cost. Your clinician decides whether a dose change is appropriate.
How is this formulation different?
This lower-dose injection combines semaglutide with vitamin B12. “Microdose” is not a standardized FDA-approved dosing category. Your clinician evaluates the reason for this combination and the prescribed dose. Explore our other semaglutide preparations: Semaglutide injections or Dissolving tablets. Each requires its own clinical evaluation.

The Evidence

What the research shows

Mechanism · GLP-1 physiology

GLP-1 is a gut hormone released after meals and cleared very rapidly.

The detail

Glucagon-like peptide-1 is a 30-amino-acid peptide hormone produced in intestinal epithelial endocrine L-cells by differential processing of proglucagon, released in response to meal intake, and inactivated extremely rapidly by the enzyme dipeptidyl peptidase-4.1

Mechanism · incretin physiology

It drives glucose-dependent insulin secretion, slows gastric emptying and promotes satiety.

The detail

As an incretin it is secreted within minutes of nutrient ingestion, and incretin-receptor activation on pancreatic islet beta-cells leads to glucose-dependent insulin secretion, while glucagon-like peptide-1 additionally exerts glucoregulatory action through slowing of gastric emptying and glucose-dependent inhibition of glucagon secretion and promotes satiety.2

FDA labeling · clinical pharmacology

Semaglutide is a GLP-1 analogue with an elimination half-life of about one week.

The same receptor
semaglutide, a GLP-1 analogue, selectively binds to and activates the GLP-1 receptor
The detail

Semaglutide is a GLP-1 analogue with 94 percent sequence homology to human GLP-1 that selectively binds to and activates the GLP-1 receptor, and FDA labeling describes the resulting mechanism as glucose-dependent stimulation of insulin secretion and lowering of glucagon secretion with a minor delay in early postprandial gastric emptying, and identifies albumin binding as the principal mechanism of protraction behind an elimination half-life of approximately one week.3

FDA labeling · clinical pharmacology and animal studies

Labeling describes GLP-1 as an appetite regulator acting in the brain.

The detail

FDA labeling further describes glucagon-like peptide-1 as a physiological regulator of appetite and caloric intake, states that the GLP-1 receptor is present in several areas of the brain involved in appetite regulation, and reports that animal studies show semaglutide distributed to and activated neurons in brain regions involved in regulation of food intake.4

Cyanocobalamin injection labeling

B12 is labeled as essential to growth, cell reproduction, hematopoiesis and myelin synthesis.

The detail

Vitamin B12 is described in cyanocobalamin injection labeling as essential to growth, cell reproduction, hematopoiesis, and nucleoprotein and myelin synthesis, and cyanocobalamin is quantitatively and rapidly absorbed from intramuscular and subcutaneous injection sites, then transported by the binding proteins transcobalamin I and II to the tissues.5

What it does not show

FDA statement · compounded drugs

A compounded preparation is not an FDA-approved drug product.

The detail

A compounded preparation is not an FDA-approved drug product: FDA states that compounded drugs are not FDA-approved and that the agency does not verify the safety, effectiveness or quality of compounded drugs before they are marketed.6

Scope of this evidence block

Everything above is mechanism, not outcome.

The detail

No trial results are cited here. Everything above is drawn from the clinical pharmacology section of FDA labeling, which describes how the molecule acts. This block deliberately stops there rather than reproducing the separate clinical studies section in which trial results for FDA-approved finished drug products are reported, because a described pathway is not a measured outcome.3

Cyanocobalamin injection labeling

B12 labeling describes no effect on body weight, appetite or energy expenditure.

The detail

Cyanocobalamin injection labeling confines its indications to vitamin B12 deficiency due to malabsorption and to use in the vitamin B12 absorption test, and it describes no effect of vitamin B12 on body weight, appetite or energy expenditure.5

Applicability · the combination

Adding B12 to semaglutide has no established effect; FDA has not evaluated the combination.

The detail

No effect of adding vitamin B12 to semaglutide on appetite signaling, semaglutide exposure, tolerability or body weight is established in the labeling of either component, and this fixed compounded combination, at any strength, has not been evaluated by FDA as a product.56

FDA guidance for consumers

FDA advises compounded drugs only when no approved drug fits, and flags equivalence claims.

The detail

FDA advises that compounded drugs should be used only in patients whose medical needs cannot be met by an FDA-approved drug, and identifies a claim that a compounded drug is the same as an FDA-approved drug as a warning sign for consumers.7

Important Safety Information
Boxed warning

FDA-approved semaglutide products carry a boxed warning concerning thyroid C-cell tumors observed in rodents. That warning is why a personal or family history of medullary thyroid carcinoma or MEN 2 is a contraindication.

Do not use if you have

  • A personal or family history of medullary thyroid carcinoma or MEN 2
  • Sensitivity to cobalt or vitamin B12

Serious risks

  • Pancreatitis
  • Gallbladder disease
  • Acute kidney injury following the fluid loss that severe vomiting or diarrhea can cause
  • Serious hypersensitivity reactions have been reported after parenteral administration of injected vitamin B12

Commonly reported

  • Mostly gastrointestinal: nausea, vomiting, diarrhea, constipation, and abdominal pain
  • Alongside that, soreness or redness where you inject

Pancreatitis history and pregnancy plans are reviewed before anything is prescribed. Injected vitamin B12 carries its own labeled cautions. Those risks are described for the individual components rather than for this compounded combination, which has no safety database of its own. Your clinician is the one who decides whether it belongs in your case.
