How it raises your testosterone
Ten clinically dosed ingredients with one job: move the number on your next blood panel.
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.
A lot of the testosterone you make is bound up and unavailable. Boron, Shilajit and Forskohlii work on the free, usable fraction, so the T you make is T you actually feel.
Zinc, magnesium and D3 are what production runs on, and hard training burns through all three. Run low and everything upstream stalls. This keeps the tank full, in forms your body absorbs.
What they say about
the Ultimate Testosterone Booster
When the number moves, everything moves with it. Here's what changed for the guys who train for a living.
@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
Most boosters hide behind proprietary blends. This is the entire formula, doses and all.
Every dose printed on the bottle you receiveThis is why it shows up on bloodwork, and why most boosters never will.
NattyPLUS vs
the rest
Six differences. Only one brand shows up on a blood panel.
NattyPLUS
Others
One of these was built to be sold. The other was built to be tested.
We love supplements.
We hate this industry.
Hey, Joe and Riley here.
What we can't stand is an industry where most products aren't built to actually do anything. Underdosed, single pathway, and designed to look good on a label instead of move anything on a blood test.
So we built the opposite. Every ingredient loud and proud on the front of the bottle, at doses proven in trials, in the forms your body can absorb. No proprietary blends. No filler. No hype.
We're not asking you to trust us on faith. If you ever want to know for certain, get a blood test before you start and again a few months in, and let the numbers settle it. Plenty of customers have done exactly that, and their panels are further up this page.
Honestly? We'd rather you find out it isn't working and stop buying, than keep paying us for something that isn't moving the needle.

I've been using the Testosterone, and Blood Sugar supports for a few months now. And if you're on the fence, get off it and get on these supps. I'm waking up ready to go (lads, you get it) and I haven't had this much energy since my 20s. I have no brain fog and my mood is incredible. These are the first supps I've stuck to because I simply cannot go back. Please boys, if you're not sure, this is your sign.
Massive fan of their testosterone booster, have be using it for just under a year, it helped increase my lifting on my squat bench and deadlift as well as improving my physique. To get the different elements all in one is a absolute saver. Alongside this considering that it's international shipping it's not much longer than a week from order to delivery. Definitely one supplement I plan to keep in rotation.
When I first started using natty plus supplements I had a subscription of the ultimate testosterone booster. It gave me the drive and motivation to keep going when I might have given up in the past. Around six months in the EOFY sale came around and I took the plunge and upgraded to the ultimate performance bundle. I would not look back and I can honestly say that the cost is justified by the results.
Early days but definitely starting to feel the benefits of the test booster. The sleep supplement is also a game changer, knocks me right out. Loving it
Frequently asked questions
Every doubt we hear, answered straight.
You've tried underdosed, single pathway formulas built to look good on a label. You didn't fail. The formula did. This is ten ingredients at clinically studied doses, every one printed on the front. And if you ever want certainty, a blood test before and after will settle it either way.
Compare the label. Tongkat Ali 300mg, Fadogia 300mg, Anacyclus 400mg, and the other seven, all printed on the front of the bottle. No proprietary blends, nothing hidden, and every batch is third party tested for purity and potency.
There are no hormones in the bottle. It supports your body's own production rather than replacing it or shutting anything down. Natural ingredients at researched doses, manufactured to GMP standard with a certificate of analysis on every batch.
Three capsules a day, every day. One bottle is a 30 day supply. Consistency matters far more than timing, so take them whenever you'll actually remember.
Most men report energy, drive and mood shifting within the first few weeks. Hormones respond to steady signal over weeks rather than days, so give it a full 8 to 12 weeks before you judge it, and longer again if you want to see the change on a panel.
For some men, eventually, maybe. But TRT is a lifelong commitment, and most guys jump to it without ever finding out what their own system can do with proper support. This is the rational step before that decision.
Yes. It stacks with the rest of our range and with most standard supplements. If you're on medication or under a doctor's care, check with them first.
