Creatine monohydrate is a naturally occurring compound that your body uses to regenerate ATP — the primary energy currency of your cells. It is, by a wide margin, the most researched sports supplement in history, with over 500 peer-reviewed studies confirming its safety and effectiveness for increasing strength, power, and lean muscle mass. It's not a steroid, it's not dangerous, and monohydrate is the only form you need.

L-Carnitine is a naturally occurring compound that transports long-chain fatty acids into your mitochondria, where they're burned for energy. It's made in your body from the amino acids lysine and methionine, and it's found in red meat and dairy. For exercise, the most relevant form is L-Carnitine L-Tartrate (LCLT) — the form researched for muscle recovery, reduced exercise-induced damage, and fat oxidation during training. PurePump uses 500mg of Carnipure (branded LCLT from Lonza) per serving. Important caveat: L-Carnitine supports fat oxidation. It does not independently cause fat loss.

All caffeine shares the same molecular structure (C8H10N4O2), but how it's produced and what comes with it matters. Natural caffeine extracted from coffee beans (Coffea) is plant-derived and contains naturally occurring chlorogenic acids — bioactive compounds with antioxidant and metabolic properties. Synthetic caffeine anhydrous is manufactured from urea and chloroacetic acid in a chemical synthesis process. PurePump uses 200mg of natural caffeine from coffee bean (at 2 scoops) for clean energy from a natural source.

L-Citrulline is a non-essential amino acid that your body converts to L-Arginine, which then produces nitric oxide (NO). More nitric oxide means better blood flow, more oxygen to muscles, and improved exercise performance. It's one of the most effective and well-researched pre workout ingredients available.

Beta-Alanine is a non-essential amino acid that your body uses to produce carnosine — a dipeptide stored in muscle tissue that buffers hydrogen ions during intense exercise. More carnosine means you can push harder for longer before the burn forces you to stop. It's one of the most well-researched and effective endurance ingredients in sports nutrition, and yes, the tingling is completely harmless.

Alpha Lipoic Acid (ALA) is a unique antioxidant that works in both water-soluble and fat-soluble environments — something almost no other antioxidant can do. It supports glucose metabolism (helping shuttle fuel into muscle cells), regenerates other antioxidants (vitamins C, E, glutathione, CoQ10), and serves as a direct cofactor in mitochondrial energy production. Most pre workouts don't include it. PurePump does — 100mg of ALA per serving — because managing oxidative stress and supporting glucose utilization during training are performance factors, not afterthoughts.

BCAAs (branched-chain amino acids) are three essential amino acids — leucine, isoleucine, and valine — that your body can't produce on its own. They play a direct role in muscle protein synthesis, reducing muscle breakdown during exercise, and delaying central fatigue. Leucine is the standout, acting as the primary trigger for muscle building through the mTOR pathway. The honest truth? If you eat adequate protein, you're likely getting enough BCAAs from food. But as part of a pre workout formula, they provide targeted muscle-protective support during training when it matters most.
