Regal Weight Loss

B12 Shots (Skinny Shots®)
LipoStat Lipotropic Injections

Regal Weight Loss offers premium B12 lipotropic injections — our signature Skinny Shots® — at our Sunnyvale clinic, and they’ve become one of the most popular add-ons for patients already on a semaglutide or tirzepatide program. Each Skinny Shot® is formulated with a clinically selected blend of vitamin B12, B6, choline, methionine, inositol, and other amino acids and metabolic co-factors chosen specifically for their roles in liver function, cellular energy production, and fat mobilization.

Here’s why that matters for weight loss: GLP-1 medications like semaglutide and tirzepatide work primarily by reducing appetite and slowing gastric emptying, but they don’t directly address nutrient absorption or energy levels — two areas where many patients on calorie-restricted intake start to feel the effects. Our B12 lipotropic shots fill that gap by giving your body the micronutrient support it needs to keep burning fat efficiently while maintaining the energy to stay active throughout your day.

These weight loss injections are designed for convenient self-administration — delivered subcutaneously in the abdomen or another accessible area — so Sunnyvale patients can stay on schedule between clinic visits without disrupting their routine.

What Is Medical Weight Loss?

edical weight loss is a clinician-directed approach to weight reduction that combines prescription medications, diagnostic lab work, nutritional planning, and ongoing metabolic support — all under the supervision of a licensed healthcare provider. Unlike commercial diet programs or over-the-counter supplements, medical weight loss treats excess weight as the complex, multi-factor health condition it is, using evidence-based tools to address the hormonal, behavioral, and physiological barriers that make sustained weight loss so difficult on your own.

At Regal Weight Loss Sunnyvale, that process starts with a thorough assessment of your current health, including blood work, body composition analysis, lifestyle factors, and your personal weight loss goals. Based on those findings, our medical team — led by a board-certified nurse practitioner — determines whether a GLP-1 weight loss medication like semaglutide or tirzepatide is clinically appropriate, or whether an alternative protocol such as B12 lipotropic injections or a combination approach would deliver better results for your specific situation.

The key difference between medical weight loss and going it alone is accountability backed by clinical expertise. Every Sunnyvale patient receives scheduled check-ins, dosage adjustments when needed, and direct access to a provider who understands how medications like semaglutide and tirzepatide interact with your body over time. That ongoing relationship is what drives real, measurable outcomes — not just a number on the scale, but improvements in energy, metabolic health, and long-term weight maintenance.

How Fast Can You Lose Weight?

It’s one of the first questions our Sunnyvale patients ask — and the honest answer is that timelines depend on the medication prescribed, your starting weight, metabolic health, and how closely you follow your personalized plan. That said, clinical data on GLP-1 weight loss medications paints an encouraging picture, and our own patient outcomes consistently reflect what the research shows:

• Noticeable appetite suppression within the first few days — Most patients on semaglutide or tirzepatide report a significant reduction in hunger and food noise within the first week of treatment, making it easier to stay in a caloric deficit without the constant willpower battle.
• Consistent weekly weight loss with GLP-1 or lipotropic injections — Patients using semaglutide typically see steady losses of 1–2+ pounds per week once they reach a therapeutic dose, while tirzepatide — which targets both GLP-1 and GIP receptors — has shown even more pronounced results in published clinical trials.
• Measurable improvements in energy, cravings, and metabolic markers — Beyond the scale, many patients notice fewer sugar cravings, more stable blood glucose levels, and a meaningful boost in daily energy, especially when B12 lipotropic shots are part of the protocol.

Individual results will always vary, and our clinical team sets realistic expectations from day one. During your complimentary consultation at our Sunnyvale office, we evaluate where you’re starting from, discuss which medication — whether semaglutide, tirzepatide, or another option — aligns with your health profile, and map out a timeline so you can lose weight as quickly and safely as your body allows.
