Vitamin B12 Injection in Beverly Hills, CA
B12 (typically methylcobalamin or hydroxocobalamin) by intramuscular or subcutaneous injection bypasses GI absorption — useful for men with documented deficiency, malabsorption, or restrictive diets. Restores B12 status reliably within weeks.
Typically used for:
Repleting B12 in men with documented deficiency or malabsorption.
Benefits
What Vitamin B12 Injection can do for you.
Energy support
When deficiency is real, men often report meaningful energy and cognitive improvement within 1–2 weeks.
Reliable lab repletion
Injection bypasses GI absorption — corrects labs reliably even in patients with malabsorption.
Neurological support
B12 is essential for nerve myelination; supplementing deficiency helps prevent progressive neurological symptoms.
How it works
From consult to follow-up.
Initial consultation
A board-certified physician reviews your symptoms, history, and goals. At many participating clinics the first visit is complimentary.
Baseline labs
Bloodwork tailored to the protocol. Results come back in days, not weeks. We don't prescribe before we have your numbers.
Personalized protocol
Your physician calibrates your dose based on your labs and your goals — not a template. Adjustments happen as your data evolves.
Ongoing follow-up
Recheck visits at six and twelve weeks, then quarterly. Real follow-up, structured into the plan.
- Duration
- ~2 minutes for intramuscular injection
- Results timeline
- Lab repletion within 4–8 weeks; subjective energy improvements within 1–2 weeks when deficiency is present
Designed around your schedule
Consults are short
Initial visits are typically 45–60 minutes. Many participating clinics waive the fee for new patients.
Telehealth follow-ups
Where state regulations allow, follow-up visits are conducted via telehealth — no extra drive time.
Medication shipped
Prescriptions ship directly from a 503B-licensed pharmacy. No standing in line.
Quarterly check-ins
Structured follow-up at six and twelve weeks, then quarterly. Real medicine, not a one-and-done.

Don't go to a chain clinic. Go to a real physician like Dr. David Rosenberg, MD. The difference in care is night and day — labs, follow-ups, dose adjustments based on actual data.

Have referred two friends to Dr. Aleix Bazzi, MD and they've both had the same experience. Thorough intake, real labs, real follow-up. That's what good care looks like.

Came in skeptical because I'd had a bad experience at one of those big-chain places. Upsize Beverly Hills was the opposite — actual physician, actual labs, actual follow-up. Highly recommend.

I'd seen three other providers about the same issue. Dr. Aleix Bazzi, MD was the only one who actually ordered the right labs and explained the results in plain English. The protocol is working.

Front desk is responsive, scheduling is realistic, and the care plan is data-driven. Exactly what I was looking for after my last clinic kept dropping the ball on follow-ups.
