How it raises your testosterone
Ten clinically dosed ingredients with one job: move your total and free testosterone on your next blood test.
Four botanicals signal your body to ramp up its own production. This is the part you feel first: sharper mornings, training aggression, drive that shows up without being forced.
Most boosters skip it. A big chunk of the testosterone you make gets bound up by SHBG and wasted. Boron, Shilajit and Forskohlii free the usable fraction, so it's T you actually feel.
Zinc, magnesium and D3 are the raw materials production runs on, and hard training burns through all three. Run low and it stalls, so this keeps them topped up in forms you actually absorb.
Don't take our word for it.
Take theirs.

@anabolic_gabe+580% testosterone in 12 months
“I just recorded my highest ever natural testosterone, a 580% increase from 12 months ago.”
I’m dialled in with my sleep, training, recovery and diet, but so are plenty of guys who are low T. My secret weapon is the Ultimate Testosterone Booster. Six months in and I’m leaner and stronger than I’ve ever been.

@alexmilovanovEnergy, sleep, motivation and drive through the roof
“Energy, sleep, motivation, drive, everything just went through the roof.”
I know there’s a lot of rubbish out there, but these guys are the real deal. When I stack it with the sleep support, it’s next level.

@rambobrahTestosterone at the top of the range
“The dosage is way higher, which is why this actually works.”
I was the biggest sucker for iHerb back in the day, flying in the dark, taking caps from all these random bottles, getting nothing. These guys put 10 researched and proven ingredients into one supplement, dosed at their clinically studied quantities. I was a customer well before I ever spoke to them about coming on board.

@jacobgracoo+74% testosterone in 2 months
“I doubled my natural testosterone.”
Coming out of my last competition season my blood work came back at just 10. I ran the Ultimate Testosterone Booster for 2 months and kept everything else the same, my training, my diet, my routine. My natural testosterone doubled. This stuff works.

@mad_nord_liftsStronger while losing weight with more energy than ever
“Dad with a hell of a lot on my plate.”
Working, looking after my daughter and trying to stay fit feels like an impossible task. Ever since taking the NattyPLUS Testosterone Booster, I felt like I’ve got even stronger while losing weight, and have had more energy than ever to do the things I love.

@leonardoly_More energy, better mood in two and a half weeks
“Does this stuff work? Hell yes it does.”
I’ve been running the Test Booster for about two and a half weeks now and I just feel overall so much better. So much more energetic throughout the day. My overall mood is just so much better.

What makes it the
Ultimate Testosterone
Booster
No proprietary blends, no sneaky sh*t. Every dose is printed loud and proud on the front.
Every dose printed on the bottle you receiveThis is why it shows up in testosterone blood test results, and why most boosters never will.
NattyPLUS vs
the rest
Six differences. Only one brand can point to real before-and-after testosterone blood test results.
NattyPLUS
Others
One of these was built to be sold. The other was built to be tested.
Most supplement companies sell
literal trash.
Hey guys, Joe and Riley here.
Supplements are supposed to work. They're supposed to improve your health, make you look and feel better, and let you see it working by checking your biomarkers.
But with all the trash out there that does next to nothing, saying that out loud has started to feel like a hot take.
So why do most companies sell literal trash? Underdosed, unbioavailable ingredients in single-pathway formulas that do nothing for you.
Because it's cheap. They'd rather pour money into marketing funnels and celebrity endorsements than into making the supplement actually work.
That's the exact thing we hated, and it's why we built NattyPLUS. The real formula on the front of the label, the correct bioforms, the studied standardisations, the doses that actually work.
It's why we've built an entire library of evidence, from human trials and customers' before-and-after testosterone blood test results, showing measurable changes. That should be the bare minimum. No one else has it.
Take Tongkat Ali. Not all of it is equal. We use the 2% eurycomanone version, where most use the cheap unstandardised one that rarely does anything.
If you've taken a natural test booster and got nothing, the booster didn't fail you, the cheap cashgrab version you took did.
We've applied that to every ingredient in the Ultimate Testosterone Booster, which is why we see 30%, 50%, 70%, even up to 200% increases in natural testosterone.

I’ve noticed a huge difference taking this for 2 months. More energy, better sleep, and more easily aroused 😈. I’m in my 40s, feels like it worked a lot better than I was expecting.
Overall Nattyplus supps have been phenomenal. The test booster and Sleep support have been particularly noticeable. Would highly recommend to anyone to try them out!!!
It helped me with my training and just overall health
Been taking the ultimate test booster for a month now and been feeling and looking great, especially this last week really starting to notice it.
Keen to continue with it and see more gains!
So here it is, after a £300 that I have debated for months on end following the adverts and discussion.
I exercise and work out as regularly as anyone that is interested in this so I know it won’t be a miracle, but an assist to go those extra steps every now and again.
From the initial delivery I was disappointed. Damage to the box exterior, no flash in personalisation from the team with damage to the internal part of the one box showing that something has been removed rather than a separately designed package for the Ultimate Turbo Bundle.
The tubs are clean and informative with dosage and ingredients. I can only give it time, three months to see true changes I can understand and look forward to reviewing over time. Maybe a look at some blood work soon but can’t say I am off to a flying start.

Frequently asked questions
Every doubt we hear, answered straight.
Test boosters don't work. I've tried them.
You've tried underdosed, single-pathway formulas built to look good on a label. The booster didn't fail you, the formula did. This is ten actives at clinically studied doses, every one printed on the front, working three pathways at once. Get a baseline testosterone blood test, run it for 90 days, retest with the same panel, and let the numbers settle it.
Is it just placebo?
Feelings can be placebo. A testosterone blood test can't. Mood and energy are subjective, but your total and free testosterone on paper are not. Get a baseline testosterone blood test, repeat the same panel after a few months, and read the difference.
How do I know it's not underdosed like the rest?
Because every dose is printed loud and proud on the front of the bottle. No proprietary blends, no hiding. Ten actives at their studied doses, in forms that actually absorb. When a brand won't show you the doses, it's usually because there's nothing worth showing.
My labs say I'm normal, but I still feel flat.
“Normal” is a huge range, and the bottom of it feels nothing like the top. Feeling flat and under-recovered while sitting in range is common, and it's usually stress, sleep, micronutrients and SHBG dragging on you, not one broken number. This supports the whole system, not a single marker.
Why not just take Tongkat Ali on its own?
Because your testosterone isn't low for one reason, so one ingredient rarely fixes it. One bloke needs production support, another needs the free fraction freed up, another's low on the raw materials. This covers all three at once, which is why it moves on a panel when a single herb usually doesn't.
Shouldn't I just get on TRT?
TRT works, but it's a serious, usually lifelong commitment: needles, medical supervision, and side effects like fertility changes to weigh up. Most guys haven't actually supported their natural production properly first. This is the step to try before that, not a replacement for it. If you're seriously considering TRT, have that chat with your doctor.
Is it safe? Will it mess with my hormones?
It supports your body's own production rather than replacing it, so it works with your system, not against it. That said, supplements can interact with medication or existing conditions, so if you take anything prescription or you're unsure, check with your doctor before starting. Everything's made to GMP standard.
How do I take it, and how long until I notice?
Take it daily and consistently, the label has the exact directions. It's not a stimulant you feel in an hour, it's built to support the systems behind your testosterone, so give it time. Natural formulas build over about 8 to 12 weeks, so run it 90 days and let a retest show you the difference.
Is it worth it, or just another supplement I'll forget about?
Fair question, most supplements are exactly that. The difference here is you don't have to guess whether it's working. Get a baseline testosterone blood test, run it for 90 days, then repeat the same panel. If your total and free testosterone numbers don't move, you'll know, and you can stop. It's also covered by our 30 day money-back guarantee, so the risk sits with us, not you.
Can I take it with my other supplements?
Yes, for most guys it stacks fine, it's built to be the foundation of a stack. One rule: don't double up on the same actives from another product, and if you take prescription medication or anything hormonal, check with your doctor first.
