  • Increase Strength and Muscle Hardness
  • Increase Sex Drive and Response to Stimulation
  • Decrease Bad (16-hydroxyestrogen) Estrogen
  • Dramatically Increase Erection Hardness
  • Increase Semen Volume and Sexual Pleasure

With DIESEL TEST™ Hardcore you will experience increased free testosterone levels, a huge jump in libido (sex drive), see increased semen volume and experience monster erections on demand BUT more importantly you will get strong as hell with increased muscle hardness, power gains, lean muscle mass gains and experience faster recovery!  There are tons of herbal test boosters out there but we guarantee nothing surpasses DIESEL TEST Hardcore in effectiveness!

DIESEL TEST Hardcore is the most complete herbal test booster available.  Some herbal test boosters increase libido with no effect on test levels.  Some increase free testosterone or total testosterone but not both and have no effect on reducing bad estrogen, cortisol or prolactin.

With this new "red bottle" formula, DIESEL TEST Hardcore hits harder and the Nitric Oxide effects are stronger than most products sold primarily as NO boosters at a price equal to or higher than DIESEL TEST Hardcore and those NO products have no effect on anything besides pumps.

Simply put DIESEL TEST Hardcore is guaranteed to out perform any herbal test booster available at increasing total and free testosterone while reducing/controlling excessive estrogen, cortisol and prolactin production.  As a libido enhancer, semen volumizer, erection enhancer and nitric oxide product nothing comes close!

The DIESEL TEST™ Hardcore difference:

  • Increase Total Testosterone
  • Increase Free Testosterone
  • Increase Libido (sex drive)
  • Increase Erection Hardness and Frequency
  • Decrease Bad Estrogen
  • Increased Muscle Hardness
  • Decrease Cortisol (stress hormone) 
  • Increase Mood 
  • Increase Motivation
  • Increase Drive
  • Increase Training Intensity
  • Increase Nitric Oxide
  • Improved Muscle to Fat Ratio
  • Less Fat in Mid-Section
  • Increased Strength/Power
  • Increased Endurance
  • Faster Recovery
  • More Endurance
  • Faster Lean Muscle Mass Gains
  • Increased Mental Clarity
  • Reduced Stress
  • Increased Response to Stimulants

- 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).

- 100% natural/herbal with no sneaky "under the radar" ingredients that may be banned in the future.

- 100% legal in any drug tested organization.

- Contains no "experimental" never consumed by humans ingredients.

Stop wasting your money on over hyped, under dosed, "gotta stack with two or three other products for results" test boosters and GET DIESEL!

** Please note this is a very effective natural/herbal testosterone and libido booster!  You may see a temporarily increase in aggression or you may become "short tempered" with a dosage over 3-4 tabs/day.  It is very probable that you will see a HUGE (and sometimes it maybe unbearable) increase in libido (sex drive).  If "extreme" results are unwanted, reduce your dosage to 2-3 tabs or less/day or use two days on one day off, or every other day.

Get Diesel Three Kings Stack By: Bill

Review posted on: 2009-09-03 11:13:29 -0400

I just finished a 32 day run of Get Diesel 3KS. I was initially planning on a 50 day run but decided to stop sooner in order to try a couple of new products that have my attention. Overall I feel that this is the best natural stack on the market and I believe that I have tried them all. It is second only to ALRI’s “Mass Stack”, but then there are some that feel that this stack is closer to a PH than a natural stack. I am committed to building naturally so I will not use go there again. Below is my honest overall impression of this stack. Strength: (7/10) – I never felt this stack “kick-in” as some describe it but I did notice a nice gradual increase in overall strength. My strength was actually highest at the very end of the run. Libido (3/10) – My libido was low throughout the run. Natty test boosters tend to kill my libido anyway. For me this is not a real big issue as this stack works like a natural Viagra and I could still perform on demand whenever my wife was in the mood. I also noticed an increase in semen volume again for me this is not an issue either way. Moreover, my “boys” were bigger and fuller throughout. I’m not sure if there is any benefit to this but in general a nice effect. Muscle Hardness and Vascularity: (7/10) – I did finally noticed a slight increase in muscle hardness and vascularity toward the end of the cycle. I have used Diesel natty products in the past and an increase in hardness was one of the most pronounced effects. This stack seemed to get there but not as fast and effect was not as pronounced as in the past. Muscle Pump: (8/10) – In general I had great pumps throughout the run. However, I was also taking either JP8 or NO Shotgun thirty minutes prior to my workouts so I’m not sure how much of this effect to contribute to each product. Both JP8 and NO Shotgun provide good pumps on their own, so my best guess is that they are primarily responsible, however I have no doubt that DTHC and DTP both contributed to the overall effect. I was using NO Shotgun most of time because of taste and it seems to work equally well for me. I also used NOS Ether from time to time but too much magnesium gives me the runs so I have to be careful. Lean Mass: (8/10) – Somewhat difficult to gauge. I began the run at a solid 185# and finished at 186# so a 1# gain. But as I said I leaned out toward the end of the run so I may have gained a bit more. Throughout my muscles felt fuller and I seemed to look bigger particularly in the chest and shoulder area. Waist measurements remained constant and I gained about a 1/8” of girth around my arms. Overall I was very pleased with my results. I will be using DTHC again in the future however DTP and Sunami is a bit iffy for me. I am somewhat concerned about the long term effects of both pregnenolone and DHEA. Both can easily be converted to estrogen. I know that DTP contains both DIM and Resveratrol (quantities unknown) for estrogen control. DIM is a solid product with a lot of research behind it but Resveratrol is yet to be proven effective in humans. I also believe that both pregnenolone and DHEA are too far upstream to be effective as bodybuilding supplements. However DTHC seems to be very solid and I feel comfortable using it long term. After a two weeks sabbatical, I am planning another natty stack. This time I will be using DTHC as a base and stacking it with Drive by AN and either Primal Male by MAN or T-Force by Omega. Both Primal Male and T-Force contain Fadogia Agrestis which looks very interesting and Drive contains Forslean another interesting product. Stacking all three I believe will provide a synergistic effect by increasing test from several different pathways. I will be taking additional DIM throughout to insure estrogen is under control. I will be posting the results on Lean Bulk forum.

As far as natty test boosters go my vote goes to Diesel Test Hardcore from Get Diesel. Hands down the best, but don't take it if you don't like punching babies while running through walls and tearing through sorority houses. Ha!

Solid product which delivers. By varying dosage one gets libido results or strength/aggr benefits. Energy, strength and recovery has increased overall, but I do experience some lethergy when I dose higher. A great natural test booster that all can benefit from and a staple for those of us in the 35+ crowd.

I trust Get Diesel products and the quality. This formula is complete and potent. I just ordered a new bottle from Nutraplanet which always has good hard to find products for the best prices. I hope Get diesel grows and succeeds in this Industry and makes money. I will buy there JPX soon as well becasue I care about what i put in my body and stay away from artificial sweetners aflavors and colors.
