Winged Treebine / Cissus Quadrangularis Explained

Winged treebine is identified on the EndoPeak label as Cissus quadrangularis, a plant studied mostly outside the specific sexual-performance claims used in supplement marketing.

What winged treebine is

The EndoPeak label lists 33.3 mg of winged treebine stem and identifies the botanical as Cissus quadrangularis. The plant has a history of traditional use and has been researched for several proposed health applications.

Its inclusion in a men’s performance formula does not establish that it has a sexual-function effect.

What the clinical literature looks like

Systematic reviews of Cissus describe a clinical literature that is heterogeneous in interventions, populations and outcomes. Small trials can generate interesting signals while still leaving substantial uncertainty.

The evidence should therefore be described by specific studied outcome rather than with a broad claim that Cissus “works.”

Dose and extract comparability

Research products may use extracts, defined ratios or doses that are not comparable with the 33.3 mg amount shown on the EndoPeak label. Without standardization details, a milligram-to-milligram comparison can be misleading.

This is a recurring issue across multi-ingredient supplements.

What the ingredient can tell us about EndoPeak

Cissus contributes to the formula’s botanical complexity, but its research does not validate the complete product. A finished formula would need finished-product testing for product-level claims.

For safety, use the label warnings and discuss multi-supplement use with a qualified professional when relevant.

Finished-product boundary: Ingredient research does not prove that the complete EndoPeak formula produces the same effects. We did not identify a peer-reviewed randomized controlled trial of the finished EndoPeak formula during this build.
