Precision Research Lean Test is a natural testosterone boosting supplement. There are hundreds of products in this category so it can be difficult to stand apart. Precision Research achieves that with Lean Test.
Most testosterone boosters fall into a few categories. Effective and really expensive, quality ingredients but under-dosed, or more or less ineffective. Lean Test is in another group all together. The combination of a natural herbal testosterone booster called Spilanthes acmella extract at a potent dose, as well as a full dose of E-Xstane (3-deoxy-delta-3, 7-oxo-DHEA) make Lean Test different.
