08 Jan 2024 --- The Applied Science and Performance Institute, US, has conducted a “first of its kind” test on American River Nutrition’s (ARN) GG-Gold geranylgeraniol supplement — derived from the annatto plant — to assess the product’s safety profiles and impact on hormone levels in healthy adult males and females. The findings indicate significant increases in total-, free- and bioavailable testosterone in a subgroup of males with low testosterone.
