#11 of 12 in 12 Testosterone Boosters, Ranked by What's Actually Been Tested
What the human studies found
- An ecdysteroid, from the same chemical family as the hormones insects use to molt. Promoted as a natural anabolic.
- The closest human study (2024) gave 11 young men single doses and measured other markers, not testosterone. The authors said the data “fail to fully support” it as a potent anabolic supplement.
- Its close relative, ecdysterone, was tested for 8 weeks in trained men: no difference in testosterone, no difference in strength.
- A 2026 lab analysis found several ecdysteroid supplements contained substantially less than their labels declared.
The studies (4)
The anchor source is a 2024 systematic review by a team of urologists (Morgado et al., International Journal of Impotence Research). They looked at 52 studies covering 27 proposed testosterone boosters. Their conclusion: most fail to increase total testosterone.
