Ingredients (2,760 milligrams per serving)
Yohimbine (10 milligrams per serving)
Yohimbine is a naturally occurring substance that’s found in several types of plants native to central and western Africa, including the bark of the yohimbe tree.
Studies show that yohimbine accelerates fat loss by increasing calorie burning and making “stubborn fat” deposits easier to lose.[9][10][11]
The details of how yohimbine speeds up fat loss in the stomach, hips, and thighs regions (the hardest spots to lean out for most people) are rather technical, but the gist is it “deactivates” a mechanism in fat cells that prevents them from being burned.[12]
In a sense, yohimbine helps “take the brakes off” of fat loss so your body’s natural fat-burning chemicals can work more effectively.[13]
Additionally, research shows that yohimbine may also improve exercise performance by staving off physical fatigue—a welcome bonus when calories are restricted for fat loss.[14]
There’s a slight catch with yohimbine, though:
Elevated insulin levels completely negate its weight-loss effects, and that means that if you want to reap its fat loss benefits, you want to use yohimbine only when you’re in a fasted state.[15][16]
The clinically effective dose of yohimbine is between 0.1 and 0.2 milligrams per kilogram of body weight.
Forge contains 10 milligrams of yohimbine per serving and just 2.5 milligrams per pill to allow for maximum flexibility in dosing, as optimal intake depends on body weight.
This also allows for maximum safety.
While yohimbine is generally well tolerated in lower (but still effective) doses, overdosing can cause various negative side effects, including agitation, anxiety, hypertension, and tachycardia.[17]
This is why people with anxiety or panic or trauma disorders (like PTSD) are not advised to take yohimbine.
So, for example, a clinically effective dose of yohimbine for a 150-pound woman would be 7 to 13 milligrams, and one serving of Forge (4 pills) fits nicely in the middle.
Furthermore, if she feels good at this dose, she could add an additional capsule to each dosage and reach the top of the clinically effective range.
A clinically effective dosage for a 200-pound man, however, is higher: 9 to 18 milligrams. In this case, he could start with 4 pills per dosage to assess tolerance and move up to 6 to 7 for the maximum dose for his body weight.

β-Hydroxy β-Methylbutyrate (2.5 grams per serving)
β-Hydroxy β-Methylbutyrate, also known as HMB, is a substance formed when your body metabolizes the amino acid leucine, which is an amino acid that directly stimulates protein synthesis.[18]
HMB is often sold as a muscle-building aid, but the research purported to demonstrate these benefits is shaky at best.[19]
Well-designed studies do show that HMB is an effective anti-catabolic agent, however.[20]
That is, it’s good at reducing muscle breakdown rates, which can help you recover faster from your workouts and experience less muscle soreness.
This also makes HMB perfect for use with fasted training because its anti-catabolic effects can counter the increased muscle breakdown rates that occur when exercising in a fasted state.[21]
In this way, HMB helps you reap all the fat loss benefits of fasted training with fewer problems related to muscle loss.
It’s also worth noting that HMB is superior to leucine in suppressing muscle breakdown.[22] This means it’s also more effective than BCAA supplements because they rely on leucine for their anti-catabolic effects (isoleucine and valine are very weak in this regard).[23][24]
The clinically effective dose of HMB is between 2 and 3 grams.

CDP-Choline (250 milligrams per serving)
CDP-choline (also known as citicoline) is a chemical that occurs naturally in the brain and increases levels of another chemical called phosphatidylcholine, which is vital for brain health and function.
CDP-choline can also increase levels of a neurotransmitter known as acetylcholine, which is a neurotransmitter involved in learning and muscular contraction.
Research shows that supplementation with CDP-choline improves focus and memory (and verbal memory in particular) and mitigates cognitive decline as we age.[25][26][27][28][29]
For attentional purposes, the clinically effective dose of CDP-choline is between 250 and 500 milligrams.

No Artificial Food Dyes or Other Chemical Junk
Studies show that artificial food dyes may cause negative effects in some people, including gastrointestinal toxicity and behavioral disorders.[30][31][32][33][34]
