Quick answer: A third-party page reports eight Maxentra ingredients: Tongkat Ali, Tribulus terrestris, horny goat weed, saw palmetto, hawthorn berry, chrysin, Cissus quadrangularis and magnesium. No doses are published. Evidence for most is limited, and several interact with heart, prostate or hormone medicines.
Spec sheet
First, an honesty note
Reported, not confirmed: the brand images show no Supplement Facts panel. The eight ingredients here come from a third-party Maxentra page, which also mixes in brain and nerve-health wording copied from another product. We do not invent doses; read the label on the bottle you receive.
The reported ingredients
Tongkat Ali (Eurycoma longifolia)
A Southeast Asian root. Small trials at 200 to 400 mg of extract a day found modest improvements in stress hormones and testosterone, mainly in men with low levels. Product quality varies widely.
Tongkat Ali research on PubMedTribulus terrestris
A traditional herb common in men's formulas. Reviews find it does not raise testosterone in healthy men; a few small trials report better desire scores.
Tribulus research on PubMedHorny goat weed (Epimedium)
Contains icariin, studied in the lab for blood flow. Human evidence is very limited, and high doses have been linked to dizziness and fast heart rhythm.
Epimedium research on PubMedSaw palmetto
A palm berry extract mostly used for urinary symptoms of an enlarged prostate. Large NIH-funded trials found it worked no better than placebo for those symptoms.
NCCIH on saw palmettoHawthorn berry
A traditional heart tonic. It may affect blood pressure and can interact with heart medicines such as digoxin and nitrates.
NCCIH on hawthornChrysin, Cissus and magnesium
Chrysin is a flavone sold as an "estrogen blocker", but it is poorly absorbed and human data is lacking. Cissus quadrangularis is studied for joints and weight. Magnesium supports muscle and nerve function.
