Theatrim by Purus Labs is a modern, intelligent thermogenic formula that surpasses conventional caffeine-based fat burners. Designed to deliver clean, sustained energy, elevated mood, and mental clarity without a crash, Theatrim combines TeaCrine®, Infinergy™ (caffeine malate), SAMe, and natural extracts for a balanced and highly functional experience.

This isn't a stim-loaded bomb — it's a sit-stated capsule-based product that targets thermogenesis, focus, and mood in one. Whether you're looking to lose weight, need an all-day drive, or want mental performance without burnout, Theatrim gives you a powerful yet smooth edge.

Our Observations and User Feedback


After multiple uses and customer feedback, it's clear that it's built for people who want more than just a quick caffeine spike. The combination of TeaCrine and caffeine malate provides a stable, extended energy curve without the crash, which our customers often describe as "clean and focused."

Many users report a significant improvement in mood, enhanced productivity, and improved mental clarity throughout the day without engaging in any physical workouts. The addition of SAMe is particularly beneficial in this context as it supports motivation and reduces mental fatigue during periods of calorie restriction or extended workdays.

In short, it's one of the few things you can function on all day — no anxiety, no heart-pounding discomfort, just dialled-in focused energy. Whether used for fat loss, nootropic benefits, or both, Theatrim delivers in a calm, professional way that we appreciate.

Who Is It For?


Purus Labs Theatrim is an excellent fit for:

  • Individuals looking for a fat burner that works beyond caffeine alone

  • People who experience crashes or anxiety with traditional high-stimulant thermogenic

  • Athletes and professionals want clean energy, elevated focus, and mood support

  • Anyone combining fat loss goals with productivity and cognitive clarity

Ingredient Breakdown – Per 1 Capsule


Vitamin B12 (as Methylcobalamin) – 250mcg (4170% DV)


Supports energy metabolism, red blood cell production, and cognitive function. The methylated form ensures fast and efficient absorption.

InstEnergy™ Excitatory Blend – 278mg


A rapid absorption matrix combining:

  • Infinergy™ (Dicaffeine Malate) – Smooth, long-lasting energy with reduced crash and better tolerance than regular caffeine.

  • TeaCrine® (Theacrine) – A non-habit-forming compound similar to caffeine, known for enhancing mood, energy, and cognitive function without tolerance build-up.

  • Caffeine – For fast mental and physical stimulation.


SAMe (S-adenosylmethionine) – 125mg


A natural mood-supporting compound often used to enhance focus and motivation. It may also support liver health and joint comfort — an unusual but brilliant addition to a thermogenic product.

Citrus Bioflavonoid Complex (40% Hesperidin) – 125mg


Antioxidant-rich compounds that may aid circulation, metabolic function, and inflammation reduction, complementing the thermogenic blend.

White Willow Bark Extract (25% Salicin) – 80mg


A natural anti-inflammatory and thermogenic support agent, traditionally used alongside other fat-burning ingredients, to promote a synergistic effect.

Rauwolfia Vomitoria Root Extract (90% Rauwolscine) – 500mcg


Highly concentrated alpha-2 antagonist for mood elevation, fat mobilisation, and stimulant-like energy — very potent even at microdoses.

Dosage – Timing – Follow-Up

Advanced Users: May increase to 2 capsules per day, spaced at least 6 hours apart.
Avoid taking it in the evening due to the presence of TeaCrine and its caffeine content.
