Vicerex's formula relies on 5 main herbs. Vicerex's formulation consists of tongkat ali, horny goat weed, maca, trubulus terrestris, and ginkgo biloba. Vicerex lists that it contains both horny goat weed and epimedium grandiflorum, but in reality, they are both the same herb, so we question the listing.
Vicerex uses tongkat ali which is used in the Capatrex formula, but Vicerex doesn't disclose what concentration of tongkat ali is used. It could be a 10:1 extract, or it could be a 100:1 extract. Capatrex uses an extract of 100:1 tongkat ali, which is also known as LJ-100. We don't see any disclosure from Vicerex that suggests that the tongkat ali contained in their formulation is extracted to a high ration.
Vicerex uses horny goat weed, but again, does not disclose what extraction ratio of horny goat weed is in Vicerex. Vicerex could be using an extract of horny goat weed that is too low to provide any effect. Any horny goat weed below an extract of 5:1 would take an inefficiently large amount of horny goat weed to actually work.
