Study, Trial or Testing Result Summary
Members OnlyHuman studies
We found no human studies that test the ingredients in Univera Xtra Concentrate for male hormone health, such as testosterone levels, sex drive or related outcomes. The label lists only the product name, Xtra Concentrate, without naming each ingredient or giving the amount per serving. That means we cannot tell which compounds it contains or whether any of them reach the doses used in research. With no ingredient findings to report, there is no study evidence that this product helps or harms hormone balance in men. Six customer reviews were counted, and all of them were positive. However, no written reviews could be read, so we do not know whether those buyers were using it for hormone support or for something else. A handful of positive ratings is not enough to judge whether a product works. Until the full ingredient list and doses are known and human trials on those ingredients are available, this product stays at the emerging level for this goal. Animal and cell studies are never counted.

Biohacker Summary
Members Only0 of 10 recommend it
0 of 10 biohackers on our panel recommend it
Green tea is a smaller ingredient in this product, and the panel mostly likes it: six of the ten drink it or recommend it, mainly for focus and calm energy, fat loss, and burning calories, with one saying he takes a couple of capsules in the morning. Two panelists suggest adding lemon to the tea to keep more of its beneficial plant compounds, and one rotates it with coffee. Two others give cautions: very high doses of green tea extract could harm the liver, and green tea contains oxalates and may deplete folic acid, so it may not suit pregnancy. Vitamin B6 is also a smaller ingredient in this product, and views are mixed: one panelist prefers the active form over the synthetic one, another avoids supplementing it over nerve damage concerns, and one recommends it with folate and B12 for PMS.
