Cross-referencing clinical data
A pairing appears on this page only when a trial gave both ingredients together and measured the result. Beta-Methylphenylethylamine has none that clears that bar.
Stitching two separate single-ingredient studies into a pairing is the one thing this engine will not do. When a study of the combination itself holds up at source, it lands here with its citation.
No invented synergy. Where actives were studied on their own rather than together, the record shows each on its own evidence, never a combined effect no trial measured.
Research strength. Research strength says how much work stands behind the combination. It is never a product score.
Independent record. Every finding is cited to a named trial, dated, and never written by the brand.
20 pairings are live across the library today. Checked 20 July 2026.
No study gave these as a pair, so they are not in the card above. But the reason they belong together is settled biochemistry, not a guess, so it is worth knowing.
Caffeine acts on adenosine receptors and raises circulating catecholamines while this amine releases stored noradrenaline directly. The cardiovascular effects add. Products carrying the amine almost always carry caffeine as well, inside the same undisclosed blend.
Anhydrous caffeine delivers a fast, high peak, and pairing that peak with a noradrenaline releaser compresses two pressor effects into the same window. The result is a sharper heart rate and blood pressure response than either component alone. This is the most common real-world stack for this compound.
Green tea catechins inhibit COMT, the enzyme that clears noradrenaline. Combined with an amine that increases noradrenaline release, less gets cleared per unit released. The mechanism is characterised but the size of the effect in a person taking both has not been measured.
Rhodiola constituents have weak monoamine oxidase activity in enzyme assays. Stacking that with a releasing amine puts two inputs on the same transmitter pool. Reasoning here is mechanistic and points toward caution rather than pairing.
