WELCOME TO 5150 LEGENDARY SERIES HIGH-STIM PRE-WORKOUT

If you’re a true master of the craft and lifting is your life then you already know 5% Nutrition is the only LIFESTYLE to GROW by. The very name of this product should be warning enough that you’re heading into deeper waters.

What is the meaning of 5150?

Rich Piana originally went with the name “5150” for this ultra-high stimulant pre-workout because he wanted to convey that this pre-workout was not for the ordinary, but for only the serious stim junkies among us. And while Rich wasn’t insinuating that taking a few scoops of 5150 pre-workout would result in a 72-hour “involuntary psychiatric hold”, he wanted to convey that this product meant business!

Have you grown bored of other pre-workouts, having ‘tried them all’ before getting this point?
Do the results you seek lay beyond the normal conditions of training?
Do you need to focus and energize your workout while hydrating your muscles and keeping your body anabolic?

If yes, then you may have met the qualifications to start training like a true 5%ER; to enter the territory where only a few thrive: mass monster territory. If you routinely seek the pain of a long training session and routinely need to be spotted by at least two smaller freaks of the gym, then we’d like to welcome you to 5150 Legendary Series High-Stim Pre-Workout.

STIM-CRAZY CAFFEINE COMPLEX - 513 mg

Consisting of Caffeine Anhydrous, Dicaffeine Malate, Theobromine, Green Tea, Yerba Mate Extract, Guarana Extract, Green Coffee Bean Extract, and Gotu Kola Extract. This is a precise combination of eight types of caffeine and sourced specifically to create a smooth, extended energy curve while effectively eliminating the jitters of caffeine and the “caffeine crash” that accompanies most highly caffeinated products.

The new and improved 5150 Legendary Series, High-Stim Pre-Workout has arrived. This supercharged formula will have the stim-junkies lined up, again! With just a single scoop of 5150 over 400mg of total caffeine will begin to take hold and course through your veins. Prepare yourself for what’s next, blasting yourself into a gym session fueled by a blend of caffeine frp, 8 sources:

COCOABUTEROL® Cocoa Alkaloid Extract (Theobroma caco L.)
Cocoabuterol® is a new dietary weight loss supplement to activate thermogenic fat burning within the body while boosting your energy and mood. The natural alkaloids in Cocoabuterol® can significantly increase cAMP via beta-adrenoceptor which activate thermogenic fat burning and muscle building functions. This translates to fat burning PLUS support for the building of lean muscle tissue without the side effects.

Compared with caffeine, Cocoabuterol® doesn’t have the edginess often associated with caffeine while it lasts longer and while similarly balancing the onramp and offramp of caffeine into your body, enhancing caffeine’s most desirable qualities. Because Cocoabuterol® acts to smooth out the caffeine curve, you’re unlikely to experience the shakes and jitteriness associated with excessive caffeine consumption.

CAFFEINE ANHYDROUS
Commonly used as a fast-acting energy source, Caffeine Anhydrous has been used in many of the best pre-workouts and energy-based products alike. This ingredient will assist with mental alertness as it stimulates the central nervous system, making your energy output much more enhanced in a short amount of time.

DI-CAFFEINE MALATE
What makes Di-Caffeine Malate so interesting is the time-released energy production that is so heavily influenced and reflected by this ingredient. Just like caffeine, this specific ingredient helps improve energy levels and mental focus. Best of all, Di-CM helps to improve endurance and stamina, giving you the energy to combat fatigue accrued during your workout.

THEOBROMINE
Theobromine is similar in structure to caffeine and falls into the same class of methylxanthine compounds. Although theobromine is similar in structure to caffeine, it’s only about 1/10th the strength of caffeine.

Theobromine is somewhat unique in that compared to most stimulants, it's actually been shown to decrease blood pressure. It has mild vasodilating properties, similar to the amino acid Arginine, and is believed to increase blood flow.

YOHIMBINE HCL
Yohimbine hydrochloride (HCl) is a synthetic form of Yohimbine, the active chemical found in Yohimbe Tree bark, and widely studied for its fat-loss and aphrodisiac properties. Research shows that it can increase blood flow, nerve impulse transmission, and excitability in the genital area.

OTHER SOURCES OF CAFFEINE
Caffeine sourced from Green Tea leaves, Yerba Mate Extract, Guarana Seed Extract (Paullinia cupana), Rauvolfia Canescens (Alpha-Yohimbine), Green Coffee Bean Extract (Seed), and Gotu Kola Extract (Centella asiatica).

CHOKING HAZARD
Flavor Name: Bone (S), Size: 6 Count (Pack of 1)
CHOKING HAZARD: I purchased these bones for my small Yorki.. He ate the first two without incident; however, on the third bone he unfortunately choked. As the bones wear down, they become extremely stringy, and those strands do not appear to be digestible. I had to rush my dog to the emergency room, which cost $700. Three days later, he became even sicker because he was unable to pass the remaining portion of the bone still in his stomach. I then had to take him to his regular veterinarian, where he was admitted overnight and diagnosed with pancreatitis and a severely irritated gastrointestinal tract. This entire ordeal cost me over $1,500 in addition to the initial $700 emergency visit. I am grateful that my dog is now alive and well, but these bones pose a serious choking hazard and do not digest properly. I strongly caution other pet owners, especially those with small dogs.

High-Quality Magnesium That’s Gentle and Effective
Size: 90 Count (Pack of 1)
This magnesium glycinate is easy to take and very gentle on the stomach compared to other forms. It absorbs well and is a great option for supporting relaxation, muscle comfort, and overall well-being. It’s especially helpful for easing tension and can support better sleep when taken regularly. Magnesium glycinate is known for its high absorption and calming effects without causing digestive upset. The capsules are a bit larger, but still manageable and worth it for the quality. Overall, a reliable and effective magnesium supplement.

Gentle Gentle Magnesium That Helped My Night Routine
Size: 90 Count (Pack of 1)
I bought the Thorne Magnesium Glycinate Capsules (90 servings) for $25 because I wanted a magnesium supplement that could support relaxation and better sleep as part of my nightly routine. I’ve been taking it for about a month and noticed I feel more relaxed in the evenings and wind down easier before bed. I also tend to get tension and poor sleep when I’m run down, so having magnesium in my routine has been helpful for overall balance. The capsules are easy to swallow and very gentle on the stomach, which I appreciate because some magnesium supplements can cause digestive discomfort. Magnesium glycinate is also known for being one of the more absorbable and well-tolerated forms of magnesium. I actually ran out for about a week while waiting for my reorder, and that’s when I realized how much I liked having it in my routine. Once I started taking it again, it quickly became part of my evening habit. The only downside is the price is higher than some other magnesium brands, but Thorne has a strong reputation for quality and third-party testing, which is why I chose it. Overall, this feels like a high-quality magnesium supplement and a good option if you’re looking for a gentle, easy-to-tolerate form of magnesium.

Superior Quality & Effective
Size: 90 Count (Pack of 1)
Thorne Magnesium is a total game changer! The quality is exceptional, and it has finally helped me get the restful sleep I've been missing. I’ve struggled with insomnia and tried numerous other brands to no avail, but Thorne is truly superior. It is absolutely worth the investment for results that actually work.
