How Rambo almost
1.5X’d his
testosterone
naturally

Lifetime natural.
No TRT, needles or steroids.

For years, Rambo's testosterone sat around 550.

After three months of fixing his routine and taking the Ultimate Testosterone Booster every morning, his next blood test came back at 810.

Almost 1.5XIncrease in his testosterone levels

And his LH and FSH came back normal, so his body was still making testosterone on its own.

I trained six days a week and my testosterone never moved

I'll keep it real with you. I've never touched gear. Lifetime natural.

Six days a week in the gym. Coaching clients all day, training at 7 at night. Doing everything you're meant to do.

And my testosterone was always sitting around 550. Year after year, same number.

Not low enough to worry a doctor. Nowhere near what you'd expect from a guy training the way I do.

I was crashing by 3pm and dragging myself through night sessions

“I always get like a crash around like 3, even around lunchtime.”

Training at night made it worse. By the end of my session I was done. I just wanted to leave and go home.

My sleep was hit and miss. My energy didn't match my physique.

When you train like I do, you expect your body to back you up. Mine wasn't.

I had a table full of random herbs. None of them did a thing.

So I did what most guys do. I bought whatever a mate or a Reddit thread said would lift my testosterone.

I was the biggest iHerb customer going. Tongkat Ali, cistanche, black ginger, all these random bottles.

I was flying in the dark, taking caps from all these random bottles, getting nothing.

What I worked out later: the ingredients that work for some guys don't work for others. Everyone's testosterone is low for different reasons.

Taking one herb at a time was a guessing game.

I fixed the basics first. Food, sleep, recovery, no booze.

No capsule does it on its own. I changed how I lived first.

  • Stopped drinking
  • Swapped long runs for steps
  • Stopped overtraining and made recovery the priority
  • Got my food on point
  • Sorted my sleep

I wasn't trying to force one number up. I was giving my body a reason to make testosterone again.

The Tongkat Ali I was buying was only 100mg

Routine dialled in. But every test booster I looked at was the same story. One or two herbs, tiny doses.

The Tongkat Ali I'd been buying off iHerb? Only 100mg.

I was paying for a shelf full of bottles and still piecing it together myself.

Then I found the NattyPLUS Ultimate Testosterone Booster

I was a customer well before I ever spoke to them about working together.

Science-backed ingredients, clinical doses, the forms your body actually absorbs. All in one daily formula. Sign me up.

And they're the only supplement company I've seen that posts their customers' blood tests.

I read the label myself. 300mg Tongkat and 9 more, all in one.

The ingredient list on the Ultimate Testosterone Booster bottle in Rambo’s hand

I put my old bottles next to it and read the doses. Ten ingredients, all on the bottle:

  • Anacyclus Pyrethrum400mg
  • Tongkat Ali300mg
  • Fadogia Agrestis300mg
  • Shilajit250mg
  • Coleus Forskohlii250mg
  • Horny Goat Weed (Icariin)200mg
  • Magnesium Bisglycinate50mg
  • Zinc15mg
  • Boron6mg
  • Vitamin D330mcg

Tongkat Ali at 300mg. The one I was buying was 100mg. That's 3X the dose.

And instead of betting on one herb, it has 10 of the most researched testosterone ingredients in one capsule. It covers all your bases.

The dosage is way higher, which is why it actually works.

Three months of taking it every morning. My energy came back.

Every morning, while I kept my food, sleep, training and recovery locked in.

More energy than I've ever had. The 3pm crash stopped.

I started staying back at the gym to do extra steps on the treadmill. Unheard of for me. And I'd still get home with energy.

I was stoked, man. I couldn't believe it.
