Pre-Workout Fat Burner Supplement

Q: Why is Forge only for use with fasted exercise?

The primary active ingredient in Forge is yohimbine, which accelerates fat loss by increasing calorie burning and improving your body's ability to break down the fat trapped inside “stubborn” fat cells. That said, elevated insulin levels completely negate yohimbine’s 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. [1] [2] Basically, yohimbine acts like a key that “unlocks” stubborn fat cells so the fat inside can be burned. High insulin levels “change the locks,” so that yohimbine no longer works. This is true whether you exercise or not, but research shows that exercising in a fasted state boosts blood flow in the abdominal region, which helps you burn the “stubborn” fat in this area. In other words, fasted exercise and yohimbine work synergistically to improve fat burning in traditionally “stubborn” areas like the belly and lower back on men and the hips and thighs on women. 1 http://www.ncbi.nlm.nih.gov/pubmed/2906290 2 http://www.ncbi.nlm.nih.gov/pubmed/12323115

Q: How does Forge differ from Phoenix? Can they be used together?

Although both Forge and Phoenix are fat burners, they work in slightly different ways. Forge helps you lose fat by mobilizing “stubborn” body fat, which can then be burned for energy, but it’s only beneficial when taken before fasted training. (Forge also marginally boosts metabolic rate, but not enough to warrant taking it if you aren’t also fasted training). Phoenix helps you lose fat by boosting metabolic rate, improving the body’s ability to metabolize body fat, and reducing appetite and cravings (and carb cravings in particular), and you can get these benefits regardless of whether you’re in a fasted or fed state. As to whether they can be used together—absolutely! In fact, we created Forge to work synergistically with our fat burner Phoenix and pre-workout drink Pulse . When taken together, these three supplements are a powerful fat loss “stack” that helps you lose fat as quickly, healthily, and enjoyably as possible.

Q: How quickly will I see results with Forge?

You'll see results with Forge quickly. Most people see a noticeable increase in fat loss (and especially stubborn fat loss) within two weeks of starting it.

Q: Even if Forge helps me lose weight, will I just gain it back when I stop taking it?

No, you won't just gain back the fat you lose while taking Forge. The only way you can regain the fat Forge helps you lose is by dramatically overeating after you’re done dieting, which is a common mistake many people make.

Q: Will I lose muscle if I do fasted exercise and take Forge?

No, you won't lose muscle if you do fasted exercise and take Forge. It’s true that fasted exercise increases muscle breakdown rates, but that’s why Forge contains a clinically effective dosage of HMB. HMB counteracts these negative effects and helps preserve your muscle while training in a fasted state.

Q: How long can I safely use Forge for?

You can safely use Forge for as long as you’re cutting. It doesn’t contain any molecules that will harm you over time.

Q: What the heck is a “pre-workout fat burner”?

A “pre-workout fat burner” is a fat loss supplement that's meant to be taken before you work out. It’s not a full-fledged pre-workout supplement in the traditional sense because its primary purpose isn’t to acutely increase workout performance. It’s first and foremost a fat burner, and the fact that it can improve workout performance as well is a bonus.

Q: Should I take Forge every day?

You should take Forge every day that you do fasted exercise because the more frequently you take it, the more it can help you lose fat faster. (Interestingly, yohimbine also becomes more effective the longer you use it.)

Q: Is Forge suitable for both fasted weightlifting and cardio?

Yes, Forge is suitable for both fasted weightlifting and cardio. Actually, Forge can be taken before any type of fasted exercise, and the more intense the exercise is, the more fat you'll burn as a result.

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.[10][11][12]

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.[13]

In a sense, yohimbine helps “take the brakes off” of fat loss so your body’s natural fat-burning chemicals can work more effectively.[14]

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.[15]

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.[16][17]

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.[18]

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.[19]

HMB is often sold as a muscle-building aid, but the research purported to demonstrate these benefits is shaky at best.[20]

Well-designed studies do show that HMB is an effective anti-catabolic agent, however.[21]

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.[22]

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.[23] 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).[24][25]

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.[26][27][28][29][30]

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.[31][32][33][34][35]
