How it Works

  • PhenAprin isn’t one formula. It’s a system. Three targeted options, each built to power the four areas that matter most: thermogenesis, satiety, focus, and support for your body's natural GLP-1 response. 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 Response Support Support your body's own fullness signaling as part of an everyday routine.*

Each formula (Original, XR, and TX7) supports these areas in its own 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 formulated 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 fruit extract for thermogenesis and black pepper extract (piperine) as a bioavailability enhancer. Designed for a steady, sustained feel through the day. (Includes a small supportive amount of lithium orotate, which supplies lithium as a trace mineral, not prescription lithium.) Glucomannan is a soluble fiber that swells with water to promote fullness; the EU weight-management claim for glucomannan applies at 3 g per day, above the supportive 800 mg used here. Piperine can enhance nutrient bioavailability. European Food Safety AuthorityPMC+1

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