How It Works

The Ultimate 90-Day Testosterone Challenge

We test you, we supply you, we test you again. You do the 90 days.

1Today

Start the 90-day challenge

Claim the challenge bundle: a full 90-day supply of the Ultimate Testosterone Booster at 20% off, plus $200 AUD in free gifts.

+ 2× Bloodwork+ Nutrition Protocol+ Workout Protocol
2Day 0

Baseline bloodwork, on us

The first thing we do is pay for your baseline test. Your MediTests link and free code land in your inbox the day you join, and the test can be done at any of 5,000+ pathology centres across Australia. Get it done while your boosters are on the way. That's your starting line, on paper.

3Days 1–90

Execute the 90-day challenge

Three capsules every morning, with food. Eat and train the way the protocols lay out, and cut the everyday stuff that's quietly lowering your T. Hormones respond to steady signal over weeks, not days. That's why it's 90 days, not 7.

4Day 90

Retest, on us again

Same test, 90 days later, also paid for. Do it when you've got about a week of capsules left, in the morning, not after a big night. Then send us the panel. What moved, and by how much, in ink.

+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.

Testosterone 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.

+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.

Stronger 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.

“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.

Inside the Challenge

How the challenge raises your testosterone

Testosterone isn't a switch, it's a system. Three parts of the challenge, each with one job.

Ultimate Testosterone Booster bottle and capsulesThree capsules every morning, with food
01The SupplementUltimate Testosterone Booster. Ten ingredients, three targets.
Target 01Make more of it

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.

Tongkat Ali 300mgFadogia 300mgAnacyclus 400mgHorny Goat Weed 200mg
Target 02Keep more of it usable

Most of your testosterone is locked to SHBG, where it does nothing for you. Boron helps free it while Shilajit and Forskohlii keep the signal strong, so the T you make is T you actually feel.

Shilajit 250mgForskohlii 250mgBoron 6mg
Target 03Protect the foundation

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.

Zinc 15mgMagnesium Bisglycinate 50mgVitamin D3 30mcg
Joe training in the gymTrain for it. Sleep for it. Eat for it.
02The ProtocolsTwo guides and a cheat sheet, for everything a capsule can't reach.
Free with the challengeTestosterone Nutrition Protocol

Your hormones are built from what's on your plate. The foods that matter for testosterone, how much and when, and the everyday hormone disruptors most blokes have no idea are dragging their levels down. No starving, no 4-hour meal prep.

Free with the challengeTestosterone Workout Protocol

How to train for testosterone, not just for the pump. Plus sleep, the single biggest lever for raising your T, and how to actually get it. One bad week of sleep can undo a good month of supplementation.

From The Founders

The highest-T challenge the world has ever seen

Riley and Joe. No script, no fluff.

Riley and Joe, founders of NattyPLUSRiley & Joe, Founders of NattyPLUS

Low testosterone is a bad time. Harder to put on muscle. Harder to lose fat. Harder to get hard. Everything just runs a bit mid.

And it's not just you. The latest studies have testosterone down around 50% in a few decades. With levels at an all-time low it's no wonder young blokes are jumping on TRT at record numbers.

None of that is news. We all know how important testosterone is and how little of it is going around in 2026. So instead of playing low-T victim and having a sook about it, we decided to do something. We want to raise your natural testosterone by up to 94%. We've got a plan, because we've already done it dozens of times: 30, 50, 70, 94% increases on real panels. One bloke went up 200%.

That's the Ultimate 90-Day Testosterone Challenge. We pay for your baseline bloodwork. We send you a 90-day supply of the Ultimate Testosterone Booster, the most potent test-boosting ingredients in their best forms at their clinical doses. We give you the Testosterone Nutrition and Workout Protocols, so you know what to do and what to cut out of your day-to-day. Then at 90 days we pay for your second panel.

What other supplement company backs its product that hard? Who else pays for their customers' bloodwork?

Frequently asked questions

Every doubt we hear, answered straight.

How does the bloodwork actually work?

We pay for it, twice. Once you're in, you get a link and a discount code by email for your baseline test. Walk into a pathology centre, get it done, results back in about 48 hours. At day 90 we send the second one. Same test, same lab, so the two numbers actually compare.

Do I need a GP referral?

No. The test is booked through our testing partner, not your doctor. You'll get the booking link and your code the day you join.

When should I do the tests?

Morning, before food, on a normal day. Not after a big night on the drink and not after a night of bad sleep. Do the baseline before your boosters arrive, and the day-90 test when you've got about a week of capsules left.

How do I take it?

Three capsules every morning, with food. Riley takes his after the first meal of the day. Take it every day for the 90 days. Sporadic doesn't move a blood panel.

What if my numbers don't move?

Show us you ran it properly: both panels, the booster every morning, the protocols followed. Provide proof of all three and we work with you 100% to raise your testosterone in the 90 days. Sporadic dosing, a hard cut or a new medication will flatten a result, so run it clean and let the panel talk.

What happens if I start a cut, or a new medication, mid-challenge?

Be honest with yourself here. A hard cut, a new script or four hours of sleep a night will drag testosterone down faster than any supplement can push it up. The protocols exist so you're not fighting your own stack. Run the 90 days clean and the numbers look after themselves.

Can I stack it with anything?

Yes. The two we'd add: Ultimate Ashwagandha Complex to bring cortisol down further, and Ultimate Sleep Support, because a proper night's sleep raises testosterone more than anything else you'll do. Both optional. Don't double up on the same actives from another brand.

What do I actually get in the free gifts?

Two blood tests, the Testosterone Nutrition Protocol, the Testosterone Workout Protocol and the Testosterone Cheat Sheet. Around $200 AUD of value, none of it upsold later.

What happens after day 90?

You send us your results and we'll be as keen to see them as you are. Delivered every 90 days, cancel anytime. Whether it continues is entirely your call.

Test boosters don't work. I've tried them.

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, and you don't have to believe a word of it: the bloodwork settles it either way.

How do I know this isn't underdosed too?

Every dose is printed on the front of the bottle. Tongkat Ali 300mg, Fadogia 300mg, all ten of them. Compare it against anything in your cabinet, then check the third-party test on your batch. No blends, nothing hidden.

Is it safe? I don't want to mess with my hormones.

There are no hormones in the bottle. It supports your body's own production. It doesn't replace it or shut anything down. And because you're testing before and after, you're never guessing about what's happening inside you.

Shouldn't I just get TRT?

For some men, eventually, maybe. But TRT is a lifelong commitment, and most guys jump to it without knowing what their own system can do with proper support. This is the rational step before that decision: 90 days, measured, then you choose from data.

We pay for it, twice. Once you're in, you get a link and a discount code by email for your baseline test. Walk into a pathology centre, get it done, results back in about 48 hours. At day 90 we send the second one. Same test, same lab, so the two numbers actually compare.

Do I need a GP referral?

No. The test is booked through our testing partner, not your doctor. You'll get the booking link and your code the day you join.

When should I do the tests?

Morning, before food, on a normal day. Not after a big night on the drink and not after a night of bad sleep. Do the baseline before your boosters arrive, and the day-90 test when you've got about a week of capsules left.

How do I take it?

Three capsules every morning, with food. Riley takes his after the first meal of the day. Take it every day for the 90 days. Sporadic doesn't move a blood panel.

What if my numbers don't move?

Show us you ran it properly: both panels, the booster every morning, the protocols followed. Provide proof of all three and we work with you 100% to raise your testosterone in the 90 days. Sporadic dosing, a hard cut or a new medication will flatten a result, so run it clean and let the panel talk.

What happens if I start a cut, or a new medication, mid-challenge?

Be honest with yourself here. A hard cut, a new script or four hours of sleep a night will drag testosterone down faster than any supplement can push it up. The protocols exist so you're not fighting your own stack. Run the 90 days clean and the numbers look after themselves.

Can I stack it with anything?

Yes. The two we'd add: Ultimate Ashwagandha Complex to bring cortisol down further, and Ultimate Sleep Support, because a proper night's sleep raises testosterone more than anything else you'll do. Both optional. Don't double up on the same actives from another brand.

What do I actually get in the free gifts?

Two blood tests, the Testosterone Nutrition Protocol, the Testosterone Workout Protocol and the Testosterone Cheat Sheet. Around $200 AUD of value, none of it upsold later.

What happens after day 90?

You send us your results and we'll be as keen to see them as you are. Delivered every 90 days, cancel anytime. Whether it continues is entirely your call.

Test boosters don't work. I've tried them.

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, and you don't have to believe a word of it: the bloodwork settles it either way.

How do I know this isn't underdosed too?

Every dose is printed on the front of the bottle. Tongkat Ali 300mg, Fadogia 300mg, all ten of them. Compare it against anything in your cabinet, then check the third-party test on your batch. No blends, nothing hidden.

Is it safe? I don't want to mess with my hormones.

There are no hormones in the bottle. It supports your body's own production. It doesn't replace it or shut anything down. And because you're testing before and after, you're never guessing about what's happening inside you.

Shouldn't I just get TRT?

For some men, eventually, maybe. But TRT is a lifelong commitment, and most guys jump to it without knowing what their own system can do with proper support. This is the rational step before that decision: 90 days, measured, then you choose from data.
