Testncrease® (Curculigo and Fenugreek Extract — Cepham)

Curculigo orchioides (root) and Trigonella foenum-graecum (seed)
Evidence Level
Preliminary
1 Clinical Trial
2 Documented Benefits
1/5 Evidence Score

Testncrease is a patented ingredient from Cepham Inc. that combines root extract of Curculigo orchioides, a plant considered a sexual tonic in Ayurvedic medicine, with fenugreek (Trigonella foenum-graecum) seed extract. It is standardized to curculigosides and protodioscin and sold at 500 mg a day. The maker says it raises free testosterone and supports stamina, but no trial of the blend is indexed on PubMed, so those claims cannot be checked. Its fenugreek half has been tested on its own: a recent review of randomized placebo-controlled trials in men found a small rise in total testosterone with very low certainty and no reliable change in free testosterone. The Curculigo research cited here was done in rats. Evidence for the blend itself is therefore preliminary.

Studied Dose 500 mg a day is the maker's stated serving. No published trial of Testncrease reports a tested dose or duration; fenugreek trials used other extracts.
Active Compound Curculigo orchioides root extract standardized to curculigosides, combined with Trigonella foenum-graecum seed extract standardized to protodioscin; the ratio and percentages are not given in the listing.

Benefits

Healthy testosterone level support

No trial of Testncrease is indexed on PubMed. Its fenugreek component has been tested: a review of randomized placebo-controlled trials in adult men found a small rise in total testosterone with very low certainty, and no consistent change in free testosterone, the outcome the maker highlights. Those trials used other fenugreek extracts, not this blend.

Supported by Trial 1

Fenugreek among herbs studied for male testosterone

Across 32 randomized trials of 13 single herbs in men, 9 found a significant rise in testosterone, and fenugreek seed and ashwagandha extracts had the most positive results. Most trials were small, only 6 had a low risk of bias, and half enrolled men under 40, so the results may not apply to older men or to this blend.

Mechanism of action

1

Fenugreek glycosides (proposed)

Fenugreek extracts are standardized to steroidal glycosides such as protodioscin, which have shown androgenic and anabolic effects in male studies according to a review of fenugreek trials. The trials measured hormone levels, not how the glycosides act, so the mechanism in people is unproven.

2

Curculigo orchioides in rats

In diabetic male rats, a water extract of Curculigo orchioides at 100 and 200 mg/kg for 28 days improved mating behavior, sperm count, erection measures and seminal fructose, which the authors linked to antioxidant and anabolic activity. These are rat results at high doses and have not been tested with Testncrease in people.

Clinical trials

Fenugreek Preparations and Testosterone in Men: Review of Randomized Trials
PubMed

Systematic review and meta-analysis of randomized placebo-controlled trials of oral fenugreek preparations in adult men, searched to May 2026; none tested Testncrease (Yang et al. 2026, Front Nutr).

13 studies; 6 contributed to the total testosterone analysis and 5 to the free testosterone analysis.

Total testosterone rose slightly with fenugreek (standardized mean difference 0.25), but free testosterone did not change reliably (0.08, with high heterogeneity). No study had a low overall risk of bias, certainty was very low for both outcomes, and the authors concluded the evidence does not support testosterone-boosting claims.
