WHY DIESEL TEST PRO CYCLE
More Than Just the most effective legal "Test Booster" on earth....
Following the success of DIESEL TEST Hardcore, first released in 2005, GET DIESEL introduced an even more advanced formula in 2009—DIESEL TEST Pro Cycle.
Rather than creating another version of DIESEL TEST Hardcore, GET DIESEL developed an entirely new flagship formula by combining the performance philosophy of DIESEL TEST Hardcore, the hormonal support found in RAW TEST, and the enhanced libido support that made Coq DIESEL so popular. The result was DIESEL TEST Pro Cycle—GET DIESEL's most comprehensive men's performance formula.
DIESEL TEST Pro Cycle is much more than an herbal testosterone support formula. It is High Performance Training Fuel.
DIESEL TEST Pro Cycle was developed to help amplify the results of hard training by supporting strength, lean muscle, motivation, mental focus, recovery, healthy testosterone levels, libido, and overall performance.
Hard training builds muscle. Progressive overload builds strength. Creatine, quality protein, and intelligent nutrition support growth and recovery. DIESEL TEST Pro Cycle was formulated to complement that entire process—not replace it. DIESEL TEST Pro Cycle helps you get more from every workout while maximizing the results of the effort you put into your training.
Unlike ordinary "test boosters," DIESEL TEST Pro Cycle doesn't focus on one benefit alone. DIESEL TEST Pro Cycle supports the mental and physical demands of serious training, including GET DIESEL's signature nootropic support for focus, determination, and training intensity. DIESEL TEST Pro Cycle also complements creatine, nitric oxide products, protein, and pre-workouts, helping support every aspect of your performance program.
One of the characteristics that separates DIESEL TEST Pro Cycle from traditional testosterone support products is its ability to function as a low-stimulant pre-workout. Many users experience greater workout intensity, training drive, motivation, focus, and an even stronger libido response, making DIESEL TEST Pro Cycle a unique combination of hormonal support and performance enhancement.
KEY DIESEL TEST PRO CYCLE INGREDIENTS
Every ingredient in DIESEL TEST Pro Cycle was selected with one objective—to help amplify the results of your training.
High-Icariin Epimedium (Horny Goat Weed) - Not all Horny Goat Weed is created equal. DIESEL TEST Pro Cycle uses high-Icariin Epimedium, a premium extract that has remained a cornerstone of the DIESEL TEST formula for more than 20 years. High-Icariin Epimedium supports healthy libido, vitality, nitric oxide production, and muscle pumps, making it an excellent complement to strength training and pre-workout formulas. While the cost of high-Icariin Epimedium has more than tripled since COVID, GET DIESEL chose to preserve formula quality rather than remove or replace one of its key performance ingredients.
Nettle Root - We select Nettle Root standardized for its active lignans, compounds believed to support healthy free testosterone by interacting with Sex Hormone-Binding Globulin (SHBG). While total testosterone is commonly discussed, free testosterone is the biologically active form available for the body to use. By helping support healthy free testosterone levels, Nettle Root complements the DIESEL TEST formula by supporting strength, recovery, motivation, libido, and overall male performance.
Rhodiola rosea - One of the world's best-known adaptogens, Rhodiola helps support training drive, motivation, focus, recovery, and the body's ability to adapt to physical and mental stress.
Bacopa monnieri - Bacopa is part of GET DIESEL's signature nootropic philosophy. It supports mental focus, concentration, and cognitive performance, helping create the mindset needed for productive, high-intensity training.
DIM (Diindolylmethane) - DIM supports healthy estrogen metabolism and hormonal balance, making it an important component of a well-rounded herbal performance formula designed to support healthy testosterone levels.
Tribulus terrestris (Standardized for Protodioscin) - Not all Tribulus is created equal. DIESEL TEST Pro Cycle uses standardized Tribulus selected for its protodioscin content, a recognized marker of quality. Tribulus has remained a cornerstone of performance formulas because of its traditional use in supporting vitality, libido, and training performance.
DHEA - DHEA (Dehydroepiandrosterone) is a naturally occurring hormone produced primarily by the adrenal glands and serves as a precursor to testosterone and estrogen. Natural DHEA production declines with age, making supplementation increasingly popular among active adults. In DIESEL TEST Pro Cycle, DHEA complements the herbal performance formula by providing an additional level of hormonal support.
Yohimbe - Yohimbe has long been valued by strength athletes for supporting workout intensity, circulation, energy, and libido. In DIESEL TEST Pro Cycle, Yohimbe works with the complete formula to support training drive, mental focus, motivation, and the low-stimulant pre-workout effect that has made Pro Cycle unique within the DIESEL TEST line.
WHY ARE MOST TEST BOOSTERS DIFFERENT TODAY?
The natural testosterone support category isn't what it was 15 or 20 years ago.
Beginning around 2016–2018, two major changes reshaped the industry. Increased FDA scrutiny caused many companies to move away from certain ingredients, while the cost of key botanical ingredients—including Epimedium (Horny Goat Weed), Tribulus, Rhodiola, and other adaptogens—rose dramatically.
For many companies, the answer was simple: reformulate, remove expensive ingredients, lower dosages, or abandon the category altogether. That's one reason so many of today's "test boosters" look very different than the formulas that built the category years ago.
GET DIESEL took a different approach.
DIESEL TEST Pro Cycle has remained true to the performance philosophy that made DIESEL TEST one of the most respected herbal performance supplements in sports nutrition. We didn't walk away from the category when ingredient costs increased, and we didn't strip the formula down to the bare minimum simply to protect margins. Our goal has always been the same—to build a formula that supports training intensity, strength, lean muscle, motivation, recovery, healthy testosterone levels, libido, and overall performance.
THE TRUTH ABOUT "FULL LABEL DISCLOSURE"
A full-disclosure label doesn't create a better product. It creates an easier product to copy.
Today, many companies use "Full Label Disclosure" as a marketing buzzword to distract consumers from formulas that have been stripped down, underdosed, or designed around cost rather than performance. The real question isn't whether every ingredient is listed—it's whether the formula consistently delivers results.
At GET DIESEL, we've never built formulas to impress people reading a Supplement Facts panel. We've built formulas to impress people after weeks, months, and years of serious training.
AVAILABILITY
Because DIESEL TEST Pro Cycle contains Yohimbe, it is not available in countries where Yohimbe is prohibited or restricted.

DIESEL TEST® Procycle – Nothing Hits Harder with Better Results. Very Potent! The Planet Muscle Magazine 2015 & 2016 Test Booster of the Year has been upgraded again — more power, more drive, and more results. DIESEL TEST® Procycle isn’t another “natural booster” knockoff — it’s the real deal, built for lifters, athletes, and competitors who demand performance you can feel from day one. Get Diesel Nutrition took everything that made the original Diesel Test Hardcore legendary — then supercharged it by combining and adding Raw Test™ and CoQ Diesel® (libido booster) elements to create the most complete test booster available. No banned substances. No shortcuts. Just a legal, fully loaded formula engineered for maximum impact. For over 20 years, DIESEL TEST® Hardcore and DIESEL TEST® Procycle have dominated the test booster game — setting the standard for potency, purity, and results. These aren’t generic boosters; they’re proven, battle-tested formulas trusted by thousands of athletes worldwide. Where other products talk, DIESEL TEST® Procycle performs. From your first dose, you’ll notice sharper focus, stronger workouts, and that unmistakable alpha mentality that powers every rep, every set, and every goal. The unique DHEA + pregnenolone synergy supports optimal hormone balance and drive, while advanced adaptogens help manage cortisol so you stay locked in, lean, and powerful. By enhancing strength and training intensity, DIESEL TEST® Procycle helps promote lean muscle mass gains and a more favorable muscle-to-fat ratio. The result is a stronger, denser, more defined physique — and a mindset to match.
A "must have" during Post Cycle Treatment (PCT) for fast recovery of the Hypothalamic Pituitary Testicular Axis (HTPA). Effective at all age groups from 18-90+ years old! Libido (sex drive) enhancing results as early as three hours after first dose! Signs of increased free testosterone levels usually within the first 72 hours of use (which include: increased mental focus, assertiveness, motivation, positive outlook, elevated mood, aggressive workouts and that "Alpha Male" mentality). Simply put DIESEL TEST Pro-Cycle will out-perform any test booster available at increasing total and free testosterone while reducing/controlling excessive estrogen, cortisol and prolactin production.
The latest formula now includes 160 tablets per bottle — a massive value considering most users achieve outstanding results with just 3 tablets per day, far exceeding the effects of any other legal test booster. Built on the Hardcore foundation and enhanced with the strength of CoQ Diesel® and Raw Test™, DIESEL TEST® Procycle is not a 10 + 10 = 20 product — it’s 10 × 10 = 100 results. Each tablet is crafted for purity, potency, and consistency — tested annually for label accuracy and screened for select banned hormones (see more information at the company website). DIESEL TEST® Procycle helps support strength, motivation, recovery, and confidence naturally — no banned ingredients, no post-cycle therapy required. If you’re ready to move past average, it’s time to go Diesel. DIESEL TEST® Procycle – The Strongest. Still the King.
THE DIFFERENCE BETWEEN PROCYCLE AND HARCORE: Diesel Test Procycle contains Yohimbe (Hardcore doesn’t), is not for sale or shipment outside the US and is recommended over Hardcore for those who are over 35 years old, in PCT, have used pro-hormones/pro-steroids in the past or those wanting the strongest legal test booster pound-for-pound available. Procycle contains DHEA (hardcore doesn’t) therefore daily DHEA intake per day must be limited to a certain maximum (mg) amount for some individuals that compete in some WADA tested organizations.
⚠️ WARNING: Start with 1 to 2 tablets daily for the first 5 days to assess tolerance. This product is potent. Do not exceed the recommended dosage without prior experience using DIESEL TEST® Hardcore or Procycle. Take the large dose for the day closer to when you wake up, not closer to bedtime.
** Please note this is a very effective testosterone and libido booster! You may see a huge increase in aggression or you may become "short tempered" with a dosage over 6 tabs/day. It is very probable that you will see a HUGE (and sometimes it may be unbearable) increase in libido (sex drive). If "extreme" results are unwanted, reduce your dosage to 4-6 tabs or less/day.
GUARANTEED NO OTHER LEGAL TEST BOOSTER IS MORE EFFECTIVE THAN PROCYCLE
WHEN USED AS DIRECTED PERIOD!
*DIESEL TEST Procycle Stacks*
1) DTP with Raw Test for a large jump in test production (Extreme Double or Nothing Stack), works very well for those over 40 years old. Consumer 1 or 2 Raw Test with AM Procycle dose.
2) DTP with DIESEL FUEL pre-workout for increased training intensity (3-4 DTP tabs with pre-workout dose of DIESEL FUEL).
When it comes to real test boosters, no other brand hits like GET DIESEL!
