Blackstone Labs has done it again with its re-launch of Halo Elite, which is the first plant androgen (phytoandrogen) ever developed and sold in ethical doses. Phytoandrogens are substances produced in plants which have effects similar to testosterone, which regulates the development and maintenance of male characteristics by binding to androgen receptors. Blackstone Labs has found such an androgen in the plant Eucommia ulmoides which causes skeletal muscle development, bone density improvement, and increases in sex drive.

Plants containing compounds such as the isoflavonoids, with female hormone-like effects that bind to human estrogen receptors, have been known for decades. Eucommia ulmoides is the first to have corresponding male hormone-like effects that interact with the human androgen receptor. Blackstone Labs’ Halo Elite that contains a proprietary 100:1 extract (Andro 100) from the tree bark of Eucommia ulmoides and possesses bimodal phytoandrogenic and hormone potentiating effects by other lipidic components.
