About the Product
Marvelous Nutrition's Experiment is a classic stimulant pre-workout powder with a dual focus on pump and energy, formulated with a combination of vasodilating ingredients (L-Citrulline Malate 2:1 + Arginine AKG), stimulants (anhydrous caffeine + guarana 22% caffeine + synephrine 95%), performance enhancers (beta-alanine, creatine HCl, betaine), and cognitive support (L-Tyrosine, choline bitartrate, L-Taurine). Currently out of stock. Categories: Marvelous Originals / Pre-workout.
Full ingredients: L-Citrulline D-Malate 2:1 + Beta-alanine + Silicon dioxide + L-Tyrosine + L-Taurine + L-Arginine AKG + Choline Bitartrate + Creatine Hydrochloride + Maltodextrin + Flavouring + Citric acid + Anhydrous caffeine + Beetroot colouring (E162) + Guarana extract (Paullinia cupana, seed, 22% caffeine) + Sweeteners (sucralose, acesulfame K) + Sodium chloride + Citrus aurantium extract (95% synephrine).
Benefits
Citrulline D-Malate 2:1 + Arginine AKG: the dual vasodilator stack for maximum pump:
Experiment differs from Power M.F (Marvelous' other pre-workout) by including two nitric oxide precursors simultaneously—L-Citrulline D-Malate 2:1 and L-Arginine AKG (L-Arginine alpha-ketoglutarate)—instead of just one. L-Citrulline D-Malate 2:1 is the nitric oxide precursor with the highest clinical efficacy: citrulline is converted to arginine in the kidneys via the reverse urea cycle, increasing plasma arginine levels more sustainably and with less first-pass liver effect than oral arginine. The 2:1 dose (two moles of citrulline per mole of malate) ensures the ratio with the highest documented bioavailability. L-Arginine AKG (arginine salt with alpha-ketoglutaric acid) is a direct substrate for NOS (nitric oxide synthase) and has faster intestinal absorption than free L-Arginine, with AKG supporting the Krebs cycle. The combination of the two sources creates a rapid onset effect (arginine AKG) + prolonged sustenance (citrulline malate) of NO, resulting in a more intense and longer-lasting pump. The Marvelous Nutrition website, in the Arginine section, explicitly recommends mixing standalone Arginine with Experiment to maximize the pump effect.
Dual caffeine source: anhydrous + guarana 22%:
As described in multiple previous products, the combination of anhydrous caffeine (rapid onset, ~15 min) and guarana extract (Paullinia cupana, 22% caffeine, slower onset due to complexation with tannins) creates a biphasic energy profile: rapid onset with anhydrous caffeine, sustained by guarana. Experiment does not declare the total caffeine dose on the label (the composition lists ingredients without specific individual quantities), but it positions itself as a significantly stimulating pre-workout.
Synephrine 95% from Citrus aurantium: the thermogenic and adrenergic amplifier:
The Citrus aurantium extract standardized to 95% synephrine is an exceptionally high concentration of p-synephrine — much higher than the 6% synephrine extract from Life Pro's Evidenced Burner or the 15:1 extract from Marvelous' Power M.F. This means that even a small dose of extract provides a high dose of active p-synephrine. As described in the sections of multiple previous products, p-synephrine activates β3-adrenergic receptors in adipocytes (lipolytic and thermogenic) and has a moderate stimulating effect complementary to caffeine, without the cardiovascular risks of ephedrine.
Creatine Hydrochloride (HCl): the alternative to monohydrate with higher solubility:
Experiment uses Creatine Hydrochloride (HCl) instead of creatine monohydrate, which is a formulation choice that prioritizes solubility and mixing in a powdered product: creatine HCl is much more soluble in water (approximately 40 times more soluble than monohydrate), resulting in better dispersion in the pre-workout powder without clumps. Bioavailability at equivalent doses is comparable to monohydrate, but the typical dose of HCl in pre-workouts is lower than the maintenance dose of 3 to 5g/day of monohydrate (given that pre-workout is not designed as a standalone creatine supplement). For those using Experiment and wishing to saturate muscle creatine stores, parallel use of Marvelous' standalone Creatine Monohydrate is still recommended.
Beta-alanine, L-Tyrosine, L-Taurine and Choline Bitartrate: performance and cognitive support:
As described in multiple previous sections, beta-alanine buffers muscular H⁺ via carnosine, L-Tyrosine supports catecholamine synthesis for focus and alertness, L-Taurine has functions of cellular hydration, muscle membrane stabilization and modulation of oxidative stress during exercise, and choline bitartrate is the precursor to acetylcholine for neuromuscular transmission and cognitive focus (mind-muscle connection).
Usage
Recommended dose: Mix 1 serving with 250 to 300 ml of cold water, 15 to 30 minutes before training. For maximum pump, you can combine it with 4g of Marvelous Nutrition's standalone Arginine in the same shaker (as recommended by the brand's own website in the Arginine section). Start with half a dose to assess tolerance to caffeine and synephrine before progressing to the full dose.
