The Line-Up

Match Your Symptoms
to Your Injection

Four medical-grade IM formulas. Tell your provider what you’re feeling — they’ll match you to the right one, or the right combination.

01 NAD+ IM injection vial — Cellular Energy

NAD+

Cellular Energy
  • Deep, all-day fatigue
  • Mental fog
  • Slow recovery
  • Supports mitochondrial energy production
  • Supports cellular repair and renewal
  • Supports mental clarity and focus
Book NAD+

NAD+ is the direct coenzyme required for the electron transport chain inside your mitochondria — the final step where the body generates adenosine triphosphate (ATP), your fundamental unit of cellular energy. Without adequate NAD+, cells simply cannot efficiently convert nutrients into energy, making it the most potent single agent here for systemic fatigue, cellular repair, and metabolic speed.

02 Plenish IM injection vial — Total Revitalization

Plenish

Total Revitalization
  • Dehydration
  • Low B-vitamin status
  • Everyday drag
  • Full-spectrum B-vitamins plus essential minerals
  • Supports hydration at the cellular level
  • Supplies the cofactors your metabolism runs on
Book Plenish

While proprietary formulas vary slightly, complexes like Plenish typically blend a full spectrum of B-vitamins, essential minerals (like magnesium), and hydration fluid. Energy production isn't a single-molecule process; it requires magnesium as a cofactor for ATP synthesis alongside multiple B-vitamins. Plenish tackles systemic hydration and provides the essential cofactors needed across the entire Krebs cycle.

03 B3 / B1 IM injection vial — Metabolic Fuel

B3 / B1

Metabolic Fuel
  • Sluggish metabolism
  • High-carb diet
  • Low stamina
  • B3 is the precursor your body uses to build NAD+
  • B1 supports carbohydrate metabolism
  • Supports healthy metabolic function
Book B3 / B1

Vitamin B3 is the precursor your body uses to synthesize NAD+. Administering B3 gives your liver and cells the raw materials to build NAD+, but it relies on multi-step enzymatic pathways (which slow down as we age or experience stress). It is essential for carbohydrate and fat breakdown, but direct NAD+ bypasses these metabolic bottlenecks.

Thiamine (B1) is indispensable for pyruvate dehydrogenase — the key enzyme bridge that converts carbohydrate metabolism into usable fuel for the Krebs cycle. It provides a massive energy boost for patients with specific deficiencies, high-carb diets, or alcohol-related depletion. However, as a standalone agent, its metabolic scope is narrower than a multi-B complex (Plenish) or NAD+.

04 Amino Multiplex IM injection vial — Build & Recover

Amino Multiplex

Build & Recover
  • Muscle loss on GLP-1
  • Slow recovery
  • Training support
  • Essential amino acid blend
  • Supports muscle growth and repair
  • Enhances recovery and performance
Book Amino Multiplex

Amino Multiplex delivers a profile of essential amino acids — the building blocks your body cannot manufacture on its own. When calorie intake drops, as it does on a GLP-1 program, the body will draw on lean tissue to find them. Supplying those building blocks directly supports muscle maintenance, repair, and recovery while you lose weight.

The Power of Plenish + NAD+

Why this duo is the ultimate metabolic spark.

Your body’s core energy and repair systems are deeply connected. Together, NAD+ and Plenish go beyond standard vitamins to support mitochondrial function, metabolism, brain focus and cellular repair — an essential foundation for a vibrant life.
