Stimul8 by Schwartz Labs Review – Product for Men Over the Age of 30?

What Is Stimul8?

Stimul8 is a testosterone booster designed for men. The ‘off-cycle’ product is designed to be used during the period of time bodybuilders use to remove harmful toxins and substances from their body. Containing only all-natural ingredients and no prohormones, Stimul8 works to improve energy levels, increase strength, improve the ability to fight fat, and increase muscle gains through enhanced production of the natural testosterone in the body. While designed for ‘off-cycle’ use, the powerful supplement can also be used on a daily basis to improve test levels and bodybuilding and weightlifting sessions.

As the ingredients inside of this supplement blend together, users are offered workout advantages that allow explosive workouts filled with benefit after benefit. Men using this testosterone booster may feel like a younger version of themselves inside of the gym, lifting more weight than before and doing so with the heart of a tiger. With natural relaxing agents inside of the supplement, men using Stimul8 also enjoy less achy muscles following their workout.



Schwartz Laboratories manufactures the Stimul8 testosterone booster. The brand is a name well-known to those in the fitness industry, bringing more than 20 years’ of expertise and dozens of different products to the forefront. The company is based and headquartered in Cincinnati, Ohio, where they also operate their own laboratory for production of Stimul8 and their other fitness-based supplements. Aside from the Ohio, USA, location, Schwartz Laboratories has locations on each of the continents.

While Schwartz Laboratories focuses primarily on creation of fitness-based supplements, they also offer a variety of services to companies, including supplementation creation, label creation, and sales of supplements. Businesses that wish to use their services may submit an application for discount codes to offer to their customers. In addition, there is an Affiliate program available, as well as a newsletter sign-up for bodybuilders interested in learning the latest product news and information.


How Stimul8 Works?

Stimul8 works by enhancing natural levels of testosterone in a man’s body. Testosterone levels begin to decline with age, causing less desire to workout, inability to lift as much weight, lack of energy, difficulty attaining muscle and eliminating fat, and several other problems. This test booster works to send the levels of the hormone into overdrive, helping you hit the gym and attain the same benefits that you did as a young, eager and driven man. Men that use this test booster experience enhanced energy levels, easier elimination of fat, more strength and power, more desire to work out, and many other benefits.

Men choose to take one or two caplets of Stimul8, using it one time per day on an empty stomach and preferably around lunch time. Although many men find optimal results with use of only one capsule per day, adding a second may intensify results for the rest. Results vary from one man to the next, although most users state they notice minimal differences shortly after they being using the supplement.


Ingredients of Stimul8

Inside of Stimul8 are tested, proven ingredients that work together to increase the natural testosterone levels in your body. Ingredients inside include:


This is one of the ingredients bodybuilders look for when selecting a supplement. Fenugreek contains a number of concentrations important to athletic performance, including niacin, ascorbic acid, choline, potassium, and tryptophan. Disappointingly, sufficient Fenugreek dosage amounts suggest 300 mg per day for efficient results.

Tribulus Terrestris Extract

Also known as Devil’s Weed, this ingredient is known as the ‘king’ for many bodybuilders. Numerous studies have shown a spike in testosterone levels when used in a 10-day period, although those spikes occurred when 625 mg of the ingredient were consumed three times each day. Tribulus Terrestris Extract works by enhancing the LH hormone levels.

Pfaffia Paniculata

Also known as the Suma Root, this ingredient is found deep within the Amazon rainforests and is oftentimes described as ‘para tudo,’ meaning ‘for everything.’ Studies suggest weightlifters experience less pain after training and an increase in muscle size when this ingredient is used.

Eurycoma Longifolia Extract

More commonly known as Longjack, this ingredient improves recovery time after an intense workout.


This is something that the body needs in trace amounts, but for a bodybuilder, the ingredient is one that helps amp-up those workouts for lean, hard muscle gain.


This ingredient regulates blood sugar in the body, instantly increasing a lifter’s performance. It also works to help muscles uptake glucose rather than adipocytes (fat cells.)

Together these ingredients cause extreme benefits for men ready to see an increase in their muscle size, minus undesirable side effects. Although some of the ingredients inside of the supplement may cause nausea or upset stomach when used in high dosage, thorough testing of this product ensures adequate levels of each ingredient to prevent any side effects.



Bodybuilders oftentimes stack bodybuilding supplements together in order to achieve maximum benefits from their workout. Sadly, not all test boosters work well with other products. Fortunately, Stimul8 doesn’t fall into this category and stacks well with whey proteins, HGH, and other products that you might desire to use to enhance your workout. For men that desire to produce massive muscles in a short time, the ability to stack this test booster is one that is enjoyed.

The Stimul8 testosterone supplement uses only all-natural, proven and tested ingredients that have been specially formulated inside their lab in Ohio. The inclusion of only natural ingredients ensures that the product is safe for use by most healthy men 18 years of age and older while also reducing side effects that can accompany some bodybuilding supplements that are currently on the market.

Men using this testosterone booster report increased energy levels, thanks to increases in the natural levels of the hormone in the body. This increase in energy aids in exceptional workouts that also provided improved strength and more endurance, as well as benefits that ensure that you’re not down and out the day after a powerful workout.



Stimul8 is manufactured in Cincinnati, Ohio, inside of the Schwartz Laboratories facility. This facility is responsible for creation of products from some of the biggest and best names in the industry. Schwartz has a full Research & Development (R&D) team working inside of the facility, ensuring that products are made with only the highest-quality ingredients, tested for safety and effectiveness, and bottled for you. While many of the test booster manufactures use nutritional supplement guidelines when creating their products, Schwartz takes things one step further to provide consumer protection, using OTC drug manufacturing standards that are higher than those for a supplement.



Stimul8 seems to have a positive following of satisfied men using their product, at least according to some of the customer testimonials. Have a look at some of those testimonials for yourself.

Stimul8 is one of the best supplements I’ve used and I’ve been in the industry for over 10 years now. Since I began using it, I’ve felt super-human inside of the gym, lifting nearly double the weight from one month prior. I owe it all to this product. I will continue using and benefiting from Stimul8 for as long as it is around and I hope that is for many years to come.

The product does what it says; nothing more, nothing less. It isn’t one of those fancy products with a fancy price tag, but it works, and does so at a cost that doesn’t exceed my budget.

Awards & Media Coverage

Money-back Guarantee

One of the biggest disadvantages of this testosterone booster is the fact that, while unopened products are eligible for return, there is no money-back guarantee with the product. If you purchase more than one bottle of Stimul8 and find that it is not right for you, calling a customer service agent and requesting a Return Merchandise Authorization (RMA) number allows a return to be made within a period of 30-days from purchase. Orders should not be returned without first obtaining the RMA number, as returns that do not include this number are not accepted.



Ordering Stimul8 is easy and getting the product is even easier, thanks to multiple shipping options to cater to all needs. Many shoppers choose to use UPS shipping and the regular ground shipping method, which costs $4.95 for the first item and an additional $1.00 per additional bottle or item, but there are also other options available if you want to receive your order faster. Choose from 3-day delivery at a rate of $9.95 per order; 2-day delivery for an additional $14.95 per order; or overnight shipping for a cost of $19.95 per order.

Safe & Secure Checkout

An easy, safe and secure checkout process is never optional when ordering a testosterone supplement. Personal information, as well as credit card details, are at risk if a site does not have the top security measures in place to protect their customers. As a leader in the world of fitness supplements, Schwartz Labs takes customer privacy and protection seriously and goes above and beyond to keep all information secure.

One bottle of Stimul8 contains 60 capsules, allowing men to use the two-per-day maximum dosage and still receive a full month supply with just one bottle. Using the minimum dosage of only one pill per day results in a single bottle providing two months of usage. At a cost of $49.95 per bottle, the one-month supply is comparable in cost to many of the other test boosters currently on the market, but may provide significant savings when used at minimal dosing amounts.

Currently there are no other ordering options for the product, although discount codes or other special offers may be found via a Google search. Keep in mind that businesses can receive discount codes to offer to their customers for various discounts. These discount offers vary, and all businesses interested in obtaining codes must first complete an application and submit it to the company for approval.

Individuals wishing to order Stimul8 may do so using a credit card or debit card online 24 hours per day. Pre-paid credit cards are accepted as a form of payment if a credit or debit card is unavailable or if you do not feel comfortable providing your actual card information.
