EndoPeak Ingredients: What the Current Label Actually Contains
The current Supplement Facts panel lists nine active ingredients—not eight. Here are the amounts, evidence limits and the most important discrepancies to understand.
Current Supplement Facts
The label shows a serving size of 2 capsules, 30 servings per container and nine actives. [1] A label record sourced from the NIH Dietary Supplement Label Database reports the same serving size and ingredient amounts. [2]
| Ingredient | Amount / 2 capsules | Evidence note |
|---|---|---|
| Tribulus terrestris (fruit) | 500 mg | Some human sexual-function research; testosterone evidence is weak. |
| Magnesium (oxide) | 133.3 mg | Essential mineral; not proof of EndoPeak-specific effects. |
| Chrysin | 50 mg | Poor oral bioavailability limits translation of preclinical findings. |
| Epimedium / horny goat weed | 33.3 mg | Mechanistic/preclinical interest; human clinical evidence remains limited. |
| Tongkat ali | 33.3 mg | Some human testosterone evidence; dose/formulation differences matter. |
| Saw palmetto | 33.3 mg | Not supported for BPH symptom improvement when used alone. |
| Chinese hawthorn berry | 33.3 mg | Not established as evidence for the finished product's advertised outcomes. |
| Winged treebine / Cissus quadrangularis | 33.3 mg | Human research exists in other indications; not product-level proof. |
| Zinc (oxide) | 20 mg | Essential mineral; label lists 182% DV. |
Why does the seller say 8 ingredients when the label shows 9?
The current sales page introduces “8 carefully-selected ingredients” and then lists hawthorn berry, tribulus, chrysin, epimedium, saw palmetto, tongkat ali, winged treebine and magnesium. [3] The Supplement Facts panel also lists zinc, bringing the active count to nine. [4]
We treat the Supplement Facts panel as the stronger source for composition because it provides amounts and is specifically designed to disclose the formula. This discrepancy is one reason buyers should prioritize the current label over marketing summaries.
Ingredient-by-ingredient evidence
Tribulus terrestris — 500 mg
A 2025 systematic review of clinical trials concluded that tribulus has a low level of evidence for improving erectile function and found no robust evidence that it increases testosterone. [5] This is directly relevant to common marketing themes, but it still does not test EndoPeak itself.
Tongkat ali — 33.3 mg
A 2022 systematic review and meta-analysis reported a significant increase in total testosterone in men receiving Eurycoma longifolia, with results particularly relevant to hypogonadal men, while the authors said more research is needed before clinical use. [6] EndoPeak contains 33.3 mg per serving; studies can use different extracts and doses, so direct extrapolation is inappropriate.
Chrysin — 50 mg
A pharmacokinetic review notes that current clinical studies were largely negative and identifies poor oral bioavailability as a key limitation. [7] This is a good example of why a plausible biochemical mechanism should not be presented as proof of a meaningful outcome in people.
Epimedium / horny goat weed — 33.3 mg
Icariin, a constituent associated with epimedium, has been studied for PDE5-related mechanisms and erectile-function pathways, but much of this literature is mechanistic or preclinical. Human clinical evidence for EndoPeak's specific dose and finished formulation remains insufficient for a strong conclusion.
Saw palmetto — 33.3 mg
NCCIH states that saw palmetto, when used alone, probably is not helpful for urinary symptoms associated with BPH and that evidence is insufficient for other uses. [8] That evidence does not support using saw palmetto as proof of the seller's testosterone-related language.
Winged treebine / Cissus quadrangularis — 33.3 mg
A systematic review/meta-analysis of randomized trials found evidence in areas such as bone-fracture recovery and, for combination products, metabolic outcomes. It did not establish EndoPeak's advertised male-performance outcomes. [9]
Magnesium, zinc and hawthorn
Magnesium and zinc are essential nutrients. Chinese hawthorn has a history of cardiovascular research. But nutrient adequacy or an ingredient's biological role is not evidence that the EndoPeak finished formula will produce a specific sexual-performance result in a person who is not deficient.
The central evidence limitation
Ingredient evidence is not finished-product evidence.
Even when an ingredient has positive human research, studies may use a different extract, dose, population, duration or endpoint. EndoPeak combines multiple ingredients at its own doses. Without a trial of the exact finished formula, we should not treat individual-ingredient research as proof that EndoPeak itself works as advertised.
