How it Works

  • PhenAprin isn’t one formula. It’s a system. Three targeted options, each built to power the four pathways that matter most: thermogenesis, satiety, focus, and GLP-1 support. Choose the formula that matches your day, and keep moving toward your goals with precision.

    Thermogenesis & Energy Spark calorie burn and metabolic drive so your body stays switched on.*

  • Satiety & Appetite Control Feel fuller, resist snacking, and stay on track with less friction.*

  • Focus & Clarity Unlock calm concentration so you can follow through when it counts.*

  • GLP-1 Support Reinforce your body’s fullness signals to complement today’s smartest strategies.*

Each formula (Original, XR, and TX7) engages these pathways in its own unique way. Scroll down to find the option that fits your routine.

  • Phenaprin Original

    Advanced Thermogenic + Metabolic Support

    PhenAprin blends caffeine anhydrous and theobromine with L‑carnitine, taurine, L‑phenylalanine, and 7‑Keto® DHEA. It’s engineered to support calorie burn (thermogenesis) and efficient cellular energy use while you follow a sensible nutrition and activity plan. Evidence suggests caffeine can raise energy expenditure, while L‑carnitine assists fatty‑acid transport. 7‑Keto® has been studied for helping maintain resting metabolic rate during dieting.

    Best for: A classic, well‑rounded thermogenic and energy‑balance formula.

  • PhenAprinTx7

    Cognition‑Forward Thermogenic Energy 

    TX7 pairs caffeine with focus nutrients—CDP‑choline and L‑theanine—plus amino acids (L‑glutathione, L‑glutamine, L‑leucine) and chromium. The caffeine + L‑theanine combo has been shown to improve attention and task performance versus either alone, helping you feel sharp without the “wired” edge. Meanwhile, chromium helps support normal carbohydrate metabolism as part of a healthy diet. PubMed

    Best for: People who want a clean, focused lift with metabolic support.

  • PhenAprinXR

    Extended‑Release Satiety + Metabolic Support


    XR centers on glucomannan—a soluble fiber that swells with water to promote fullness—combined with bitter orange (p‑synephrine) for thermogenesis and black pepper extract (piperine) as a bioavailability enhancer. Designed for a steady, sustained feel through the day. (Includes a low dose of lithium orotate; not intended to treat mood disorders—use only as directed.) Evidence supports glucomannan’s role in weight management within a reduced‑calorie diet, while piperine can enhance nutrient/drug bioavailability. European Food Safety AuthorityPMC+1

    Best for: Those prioritizing appetite control and smooth, all‑day support without caffeine.
