Supplement FAQs

What is the supplement shelf life?

Under proper storage conditions, supplements have a two-year shelf-life after the MFG date (the MFG or Manufacturing date is printed next to the lot# on the underside of each container). If a product has been opened, we recommend consuming it within 60 days of opening.

Where are your supplements made and manufactured?

All of our dietary supplements are made in the USA and manufactured in Certified GMP and FDA registered facilities. Our manufacturers are GMP NSF certified and are thus held to very high standards.

How does Slam Fuel ensure quality and consistency of product?

Our products adhere to stringent standard operating procedures. Ingredient suppliers are carefully validated and ingredients are run through identity, micro, purity, and heavy metal testing.

Are all ingredients in Slam Fuel products approved?

Yes! All ingredients in our supplements are approved by the FDA and sports testing agencies. For a full breakdown of each ingredient in our products, please visit our content page.

Are all ingredients and ingredient amounts on the label?

Yes. All ingredients and ingredient amounts are listed on our product labels. This transparency is a core part of Slam Fuel, as all customers should know what exactly is in the products they are taking. We also take specific measures to avoid using proprietary blends, ensuring our customers know our ingredients are properly dosed and deliver their intended benefits.

Product Information Slam Pre

What are the benefits of Slam Pre?

Slam Pre has been scientifically formulated with proven, high quality ingredients in effective doses to give you the best workout possible.

■ Boosts energy

■ Laser focus

■ Increased muscular endurance and power output

■ Hydration

■ Powerful pumps

When and how should I take Slam Pre?

We recommend mixing one scoop of Slam Pre with 8-10 oz of cold water 30 minutes prior to training. Start with ½ serving to see response and assess tolerance, then gradually increase the dosage. For full effects, mix two scoops in 16 oz of water 30 minutes prior to training.

Will I have jitters or a post workout crash with Slam Pre?

No! Slam Pre has been carefully formulated with high quality ingredients to prevent jitters and crashes. Slam Pre is sugar free, and we added an important ingredient, L-Theanine, in its effective dosage amount of 200mg. L-Theanine Powder ensures a smooth, crash free stimulant release, without counteracting the effects of caffeine.

Why doesn't Slam Pre have creatine?

In clinical studies, creatine has been proven to be effective if properly loaded and maintained, which means it will be ineffective in the amount typically found in pre-workout. To properly load creatine, it is recommended to take 20-25g of creatine for 5-7 days before decreasing the dosage to 5g daily for maintenance. Many companies will add creatine to pre-workout products, however the sad truth is those taking the products will likely not get the benefits unless they are supplementing their creatine elsewhere.

How much caffeine is in Slam Pre?

Slam Pre contains 220mg of Caffeine Anhydrous. We also added 133mg of Infinergy® DiCaffeine Malate. Total caffeine per serving: 320mg

Infinergy® is a precise combination of caffeine and malic acid fused together using an ionic bond into a compound known as di-caffeine malate. Infinergy contains approximately 75% caffeine and 25% malic acid by molecular weight.

The malic acid in Infinergy works to buffer the salts in caffeine, allowing for easier digestion whilst also replenishing the energy produced by caffeine, which also helps to minimize the dreaded post-caffeine energy ‘crash’.
