Vitamin B12, the way your body uses it.
B12 is a foundational nutrient your body uses for energy metabolism, red blood cell formation, and a steady nervous system. An injection delivers it directly, and a licensed clinician decides whether it is right for you. Quiet, reviewed, and honest about what it is.

What it is
A clinician-reviewed B12 injection program
Vitamin B12 is an essential nutrient your body cannot make on its own. It plays a central role in how your cells turn food into energy, how your body forms red blood cells, and how your nervous system maintains its protective myelin coating. Most people get B12 from food, but absorption can vary with diet, age, gut health, and certain medications.
An injection places B12 into the muscle, where it bypasses the digestive step that some bodies struggle with. PepScribe offers two forms. Methylcobalamin is a compounded form, prepared by a licensed 503A pharmacy in the USA. Cyanocobalamin is available as an FDA-approved commercial form. Your clinician will discuss which form fits your situation.
This is a wellness and nutrient support program, reviewed and prescribed by a licensed clinician. It is not a treatment for disease, and it is not a substitute for evaluating any underlying condition with your own physician.
How it works
From assessment to a clinician's decision
You share your goals
A short, private assessment covers your energy, your diet, your history, and what you are hoping B12 might support. There is no live checkout. The assessment is free, and it routes to a clinician, not a shopping cart.
A clinician reviews
A licensed clinician reads your assessment, considers whether a B12 injection is appropriate for you, and chooses between the methylcobalamin compounded form and the FDA-approved commercial cyanocobalamin form. The clinician is the prescriber of record.
Your plan is dispensed
If a prescription is issued, your B12 is prepared and shipped to you with clear instructions. The compounded form is prepared in the USA by a licensed 503A pharmacy. No hidden overseas supply chain.
Our standard
Honest about what is in the vial.
We tell you plainly which form you are getting and where it comes from. Some of what we offer is a standard commercial generic. Some is compounded. We never blur the line.
Two forms, clearly labeled
Methylcobalamin is compounded in the USA by a licensed 503A pharmacy. Cyanocobalamin is available as an FDA-approved commercial form. Your clinician tells you which one you are prescribed and why.
Prepared in the USA
The compounded methylcobalamin form is prepared by a licensed 503A pharmacy in the United States. No hidden overseas supply chain. We will tell you the form, not hide it in fine print.
A clinician decides
No B12 ships without a licensed clinician reviewing your assessment and writing the prescription. The clinician remains the prescriber of record throughout your program.
Who it is for
Built for people who want their baseline back.
B12 support tends to interest people who feel their tank runs low and want a clinician to look at whether a nutrient gap is part of the picture. These are signals worth discussing, not a diagnosis.
- You feel your everyday energy is lower than it used to be
- You follow a vegetarian or vegan diet, where B12 is harder to get from food
- You are over fifty, when B12 absorption commonly declines
- You take medications that can affect how your body absorbs B12
- You simply want a clinician's read on whether B12 support makes sense for you
Persistent fatigue can have many causes. A clinician will help you understand whether B12 is a reasonable part of your wellness plan, and when to involve your own physician for a fuller workup.

Vitamin B12 injections offered here are intended as nutrient and wellness support. They are not intended to diagnose, treat or prevent any disease. Methylcobalamin is compounded and is not an FDA-approved drug; cyanocobalamin is available as an FDA-approved commercial form. A licensed clinician determines whether treatment is appropriate, and prescribes only when appropriate.
Compounded drug products are not approved or evaluated for safety, effectiveness, or quality by the FDA. Rx required.
B12 & energy questions
Things people ask before they sign up.
If something is not here, reach out, we'd rather answer it plainly than have you guess.
Is B12 FDA-approved?
It depends on the form. Cyanocobalamin is available as an FDA-approved commercial form. Methylcobalamin is compounded by a licensed 503A pharmacy and is not an FDA-approved drug. Your clinician will tell you which form you are prescribed and why.
What if I am not approved?
The online visit is free, so there is nothing to refund. You are never charged for a medication you were not prescribed. A clinician may decide it is not the right fit for you, and that is part of responsible care.
What is the difference between methylcobalamin and cyanocobalamin?
They are two forms of vitamin B12. Methylcobalamin is an active form and, here, is compounded by a licensed 503A pharmacy. Cyanocobalamin is a stable form available as an FDA-approved commercial product. Your clinician chooses the form that fits your situation.
Why an injection instead of a pill?
An injection delivers B12 into the muscle, bypassing the digestive absorption step that some people struggle with due to diet, age, gut health, or certain medications. Whether an injection is right for you is a decision your clinician makes during your review.
What does B12 support?
B12 is a nutrient your body uses for normal energy metabolism, red blood cell formation, and nervous-system function. We describe it as wellness and nutrient support. We do not promise specific outcomes, and B12 is not a treatment for any disease.
How much does it cost?
The online visit is free. If a clinician prescribes, B12 is from $49/month on the 3-month plan (or $59/month billed monthly). One price includes the medication, clinician care, and shipping. Plans are HSA and FSA eligible.
Where is the B12 prepared?
The compounded methylcobalamin form is prepared in the USA by a licensed 503A pharmacy. No hidden overseas supply chain. The cyanocobalamin form is an FDA-approved commercial product. We tell you which form you received and where it came from.
Do I administer it myself?
If your clinician prescribes a B12 injection, it ships with clear self-administration instructions. Your clinician and our support team are available for questions about your program along the way.
