Legion Forge Review

Forge is Legion’s newest fat-burner which, unlike most fat-burners, is specifically designed for training in a fasted state. The formula is pretty concise, with only three primary active ingredients: HMB, Citicoline, Yohimbine…

HMB

Hydroxy Methylbutyrate (HMB) is a metabolite of Leucine (discussed above), and about 5% of Leucine is converted into HMB after ingestion.

As Legion points out, the benefits of HMB have been seriously exaggerated by mainstream supplement companies claiming a variety of benefits.  While most of these benefits remain unproven (or disproven), research indicates that HMB is remarkably potent with regards to stopping catabolism (muscle-breakdown), and it also has virtually no influence on Insulin levels. Both of these properties make it ideal for fasted state training.

True to Legion, Forge contains a highly effective 2.5g dose of HMB per serving.  This takes the Forge formula from just a weight-loss supplement to a muscle-preservation formula as well.

Citicoline (CDP Choline)

Citicoline is a highly bioavailable source of Choline (second only to Alpha GPC) which has been shown to raise Acetylcholine levels in living model.
Acetylcholine is the neurotransmitter commonly attributed with controlling the mind-muscle-connection, and although this may be somewhat of an over-simplification, increased levels of Acetylcholine generally lead to cognitive improvements.

Forge contains 250mg of Citicoline, a standard dose which may help maintain optimal brain function during a fasted state.

Yohimbine HCL

Yohimbine acts as an alpha(2) receptor antagonist, meaning it inhibits the receptor responsible for blocking lipolysis (breakdown of fat). By blocking the action of this receptor Yohimbine allows for more lipolysis than would otherwise be possible from exercise.

To read more about the weight-loss potential of Yohimbine, check out this article.  Forge contains a highly effective 10mg dose of Yohimbine per serving, though not all individuals should attempt to take this dose.  Yohimbine is extremely potent and too much can potentially bring about unwanted side effects in certain individuals.

The Bottom Line

While we aren’t surprised to see another research-backed, clinically-dosed formula from Legion, we are (pleasantly) surprised to see what it is.  As far as we know, there are no other pre-workout fat-burners specifically designed for use in a fasted state.  Forge is ideal for those looking to maximize fat-loss and reduce catabolism during exercise, especially those who train in a fasted state.
