Cell Block80


Most Testosterone supplements just focus on boosting Testosterone, which could lead to undesirable side effects. Cell Block 80™ is formulated to address DHEA, SHBG, Cortisol, Estrogen and DHT conversion, which can all play a role in how much Free Testosterone actually reaches the Androgen Receptors, delivering the benefits most people are looking for.

Cell Block 80

Cell Block80 addresses all 5 anabolic phases...

1. Increase Testosterone precursor, DHEA1*
2. Bind SHBG2 and Increase Free Testosterone3*
3. Block Estrogen & DHT Conversion4*
4. Reduce Cortisol1*
5. Promote Prostate Health*

Cell Block 80

Researched ingredients - DM33® cactus flower extract And Organic Sensoril® Ashwagandha

What makes DM33® so amazing? In human cell research DM33® was shown to inhibit the conversion of Testosterone to BOTH Estrogen and DHT by over 80%.* This is why we named it Cell Block 80™. Two human clinical trials showed the cactus flower reduced Prostate issues by up to 80%.* In 2013, Clean Machine® was one of the first companies to use Sensoril® Ashwagandha in a testosterone supplement and was a Finalist for the Supply Side Editor’s Choice Award.

Sensoril® is a trademark of Natreon, Inc.

"Most people understand the link between testosterone and muscle growth, but the pathway to muscle growth is not a straight line. In fact, testosterone has a very complex pathway that can lead to dead ends… or undesirable side effects.

So, to understand what makes Cell Block 80™ such a breakthrough product we’ll need to follow the anabolic pathway all the way through. Cell Block 80™ addresses all 5 of the major areas where Testosterone can be inhibited from causing muscle growth. It’s not about how much T you have, it’s how much Free T actually reaches the finish line – the androgen receptor sites in the muscle. It is a long path with lots of detours and road blocks, but Cell Block 80™ is designed to help your T reach its goal of triggering muscle growth."

What's inside?

4 breakthrough ingredients That Naturally Boost Your T Levels


DM33® - 9:1 Opuntia Flower Extract

Shown in human cell research to:

  • Inhibit over 80% of 5-Alpha Reductase activity, an enzyme responsible for converting Testosterone into DHT. Elevated DHT has been linked to acne, hair loss and prostate issues.*
  • Inhibit over 80% of Aromatase activity, an enzyme responsible for converting Testosterone into Estrogen. Excess Estrogen may result in fat gain, water retention, breast growth in men and prostate issues.*
  • This amazing plant may help minimize the amount of Testosterone lost to conversion and reduce the negative effects of excess Estrogen and DHT.*

Sensoril® Organic Ashwagandha

  • Sensoril® in a double-blind, placebo controlled, Human Clinical Trial published in JANA, Sensoril® Ashwagandha increased DHEA by 32.2% and reduced Cortisol by 24%.*
  • DHEA is a master hormone that is converted into Testosterone. According to research, chronically elevated Cortisol levels inhibit testosterone production in men and can result in impotence and loss of libido.


  • Potent 12:1 extract providing Divanillyltetrahydrofuran (DVTHF)
  • For Testosterone to have an effect it has to be "Free Testosterone". Free means that T is not bound to binders like Sex Hormone Binding Globulin (SHBG).
  • The DVTHF found in Stinging Nettle was shown in research to have the highest binding affinity for SHBG.* More bound SHBG, allows for more Free Testosterone to stimulate muscle growth.
Bron citrate

Boron citrate

  • Based on a pilot study involving 8 healthy men, taking boron (5 mg, twice daily) for one week resulted in a trend toward increased testosterone within the normal range.

How does it work?

Cell Block 80 Covers all 5 Phases of Testosterone production

  • 1. Increase Testosterone precursor, DHEA1*
  • 2. Bind SHBG2 and Increase Free Testosterone3*
  • 3. Block Estrogen & DHT Conversion4*
  • 4. Reduce Cortisol1*
  • 5. Promote Prostate Health*

Why Cell Block 80?

the first and only natural Testosterone supplement with the Power of DM33®

Phase 1

Increase Testosterone Precursor, DHEA, by as much as 32%1*

DHEA is a master hormone that the body utilizes to create Testosterone. Cell Block 80™ contains Sensoril® Ashwagandha which has been proven in a clinical, human trial to give you a boost of DHEA by 32%1!*

Cell Block 80

Phase 2

Binds SHBG to increase free Testosterone2*

Up to 80% of circulating testosterone is bound to Sex Hormone Binding Globulin (SHBG). When testosterone is bound to SHBG it is essentially out of action. Research has shown that the 3,4-Divanillyltetrahydrofuran (DVTHF) in Nettle, has the highest binding affinity for SHBG of all lignans investigated so far.* Cell Block 80™ contains a potent 12:1 extract to maximize its effects.

Cell Block 80

Phase 3

Blocks Teststerone conversion to Estrogen4*

DM33®, Prickly Pear (Opuntia ficus-indica) 9:1 Flower Extract, was shown in human cell research to block over 80% of the conversion of Testosterone into Estrogen. 4*

Cell Block 80

Phase 4

Blocks the conversion of Teststerone to DHT

DM33®, Prickly Pear (Opuntia ficus-indica) 9:1 Flower Extract, was shown in human cell research to block over 80% of the conversion of Testosterone into DHT.

Cell Block 80

Phase 5

Reduce Cortisol - the stress hormone that can suppress Testosterone

Increased Cortisol has been shown to have both suppress testosterone and increase fat gain. Sensoril® Ashwagandha is clinically proven to reduce cortisol by 24%!1*

"After 8 weeks on Cell Block 80 I set a world record..."

"After 8 weeks on Cell Block 80™ I went from 213 to 194 pounds and I set a “world record” yesterday. The highest total for the double half snatch ever recorded by the IKLF.

I also placed first in the Iron Man Challenge (5 events, 10 minutes each for 50 minutes of competitive lifting) at the USAKL Bolt Competition. Thanks Team Clean Machine!"

Dan Bettcher, KOR Strength & Conditioning, San Diego, CA

Y. Salaam

"To be honest, I’m naturally very thin and I don’t even exercise. That said, I found that before I’d gotten half way through my first bottle of Cell Block 80, my arms were noticeably bigger! …just from going about my day-to-day routine (carrying my kids, etc.) and taking Cell Block 80!"


Santa Monica, CA

"This is best product I have ever tried. I am 42 6’5″ and I have been stuck on a plateau that has felt like an eternity... I am almost done with the first bottle and I picked up another today. I have made some significant gains this past month. Thank You!"

"I have been LOVING Cell Block 80! My “puffiness” has reduced significantly…I have made crazy strength gains and I feel my muscle are more solid, full…if that makes sense? 

My upper body, shoulder, back have always been incredibly stubborn to any kind of gains and now I actually have shoulders!! It has also helped with my cramps every month which are usually so so intense. Wasn’t expecting that!"



"I love it! I am a 39 year old, 6ft. 260lb. Natural Powerlifter. I gained 10lbs, gained strength, reaching new personal bests in all three lifts (squat, bench, deadlift) and feel great...

And my workout intensity has increased noticeably. My girlfriend is enjoying it too. Thank you. I look forward to using it again!"

Brian Linderson

"When taking everything into consideration Cell Block 80 is the best T supplement by far. Compared to others that are advertised as leaders in the space, Cell Block 80 naturally boosts your own natural testosterone while blocking estrogen at the same time but at a fraction of the price.

I’m currently on week 3... Already excess belly fat has been coming off, I've more energy and noticeable strength gains. A quality product!"
