Forslean -- A Powerful Nutrient Partitioning Agent

Forslean by ProSource

Nutrient partitioning is the term used to describe how macronutrients are shuttled to the cells; your body will either send the nutrients to muscle cells or to fat cells. Certain drugs and supplements have favourable nutrient partitioning effects, ie., they promote fat loss while maintaining lean body mass. Among these is a supplement with proven nutrient partitioning effects, namely ForsLean.

Landmark ForsLean Study
A recent randomized, double-blind, placebo-controlled study at the University of Kansas examined the effect of ForsLean on body composition, testosterone and metabolic rate in overweight and obese men [1]. Of the 30 individuals recruited, 15 were randomly assigned to receive ForsLean, whereas the other 15 subjects were assigned a placebo. Subjects were assessed for physiological changes a total of three times (pre, mid, post) during a 12-week trial period. Although there were no significant differences across time or among groups for daily caloric intake or resting metabolic rate, forskolin promoted favorable changes in body composition. Specifically, the ForsLean group lost 4.52 - 5.74 kilorams of fat mass while concurrently gaining 3.71 - 4.07 kg of lean body mass. The placebo group lost 0.51 - 1.91 kilograms of fat mass and gained 1.57 - 2.56 kilograms of lean body mass. Thus, the subjects of the Forslean group sent more of their incoming nutrients to muscle tissue, while the subjects receiving a placebo sent more of the incoming nutrients to fat tissue.

In other words, ForsLean acted as an nutrient partitioning agent. The reduction in fat mass in the ForsLean group was attributed by the authors to ForsLean's ability to directly activate adenylate cyclase within fat tissue, resulting in a greater release of free fatty acids.

The majority of fat loss supplements work through adrenergic receptor activation, but adrenergic receptor activation can down-regulate over time, resulting in diminished fat burning effects. However, ForsLean bypasses the adrenergic activation step and increases cAMP levels by either stimulating adenylate cyclase or by increasing the cAMP accumulating properties of catecholamines (e.g., noradrenaline). Thus, ForsLean can be used for LONG periods of time without diminished fat burning effects. In addition, ForsLean significantly boosted testosterone levels. In fact, testosterone increased 16.77 - 33.77% in the ForsLean group compared with a decrease of 1.08 - 18.35% in the placebo group. Any gym rat or athlete knows how crucial testorone is for muscle growth. Finally, this study demonstrated that ForsLean has no adverse effects on blood pressure; within both groups, a trend toward a significant reduction in systolic blood pressure (the top number is the blood pressure reading) was shown. Once you know the benefits of ForsLean, the paramount question becomes one of determining which supplemental source to add to your regimen.

ProSource produces the highest quality ForsLean product in a serving amount EQUAL to that used in the above mentioned study. Just ingest two capsules of ProSource Forslean and you get exactly the same amount the active ingredient than the study subjects. And since this is a ProSource product you can be assured that each production batch is stringently lab-tested, from raw materials to the finished product for purity, potency and bioavailability.
