The Testosterone Story You Just Read. Here's The Science Behind It.

Ishan and Ashay — chemist and sports scientist — tested their first formula on themselves, then went back to the published research and rebuilt it. Nine ingredients, five human studies, every dose explained.

You're still in the gym routine. The diet is reasonably dialled. You're doing the things you're supposed to do.

And the results have stopped matching the effort.

Recovery is slower. Sessions feel harder for the same output. The energy that used to carry you through the day — sharp at work, present at home — has a ceiling it didn't used to have.

You can't put a finger on it. Nothing you can fix by pushing harder. Because you've already tried that.

There's a reason this is happening. And it's not the one you've been telling yourself.

"Exactly what I was looking for! After doing some research on Testosterone support supplements, I chose Pure Test+ The difference in the past 2 months has been unreal.. more energy, better skin, more focus - everything I feel I have lost over the years. I feel like a new man... Rather supplements like this than TRT. 100%"

01 · THE ORIGIN STORY

Two 22-Year-Olds. A Chemist and a Sports Scientist. One Frustrating Discovery.

Ishan and Ashay were training hard, eating well, doing everything on paper — and still running below capacity. Low energy. Slower recovery. Drive that didn't match their ambition. Sound familiar?

So they went into the research. Months reviewing peer-reviewed studies on testosterone, looking for the specific ingredients and doses actually shown to support it.

What they found: an industry failing men. Proprietary blends. Underdosed ingredients. Products built for marketing, not results.

So they built Pure Test+ — one daily formula, every ingredient dosed to the science it's based on. Zinc. Ashwagandha KSM-66®. Himalayan Shilajit. Boron. Vitamin D3 & K2. No fillers. No fluff.

02 · WHY THIS HAPPENS

The Reason It's Not "Just Stress"

Testosterone falls by roughly 1% a year after 30. That's the part everyone knows about. The part they don't:

Chart: average testosterone declines from peak at age 30 to around 70% of peak by age 60

Cortisol and testosterone run on the same biological pathway. Keep stress elevated — career pressure, broken sleep, training load — and testosterone gets suppressed. Not slightly. Materially.

That's why the effort stops matching the output: recovery slows, because testosterone drives the muscle-repair process that responds to training. It's why the flatness isn't just physical — mood, stress threshold, and mental sharpness run on the same hormone.

Most men chase the symptoms — more protein, better sleep, pushing harder. None of it moves the needle, because none of it touches the actual mechanism.

03 · VERSION ONE

They Tested Version One On Themselves. Then They Rebuilt It.

Before selling a single pouch, Ishan and Ashay took the original Pure Test+ for 70 days, alongside training and a healthy lifestyle — then had their blood tested independently. The results:

Both “before” samples were drawn at 8:37pm; testosterone naturally runs higher earlier in the day, so draw times can move a single result. Two people — not a clinical trial. Individual results vary.

Two people isn't a clinical trial — and they didn't treat it like one.

So they went back to the published research, rebuilt the formula around the ingredients with the strongest human data behind them, and matched each dose to the study wherever the safety limits allow.

That's Pure Test+ 2.0. The studies are below.

It wasn't just us. Customers who retested:

★★★★★

"My Testosterone was 6.4 and after taking Pure Test + for just over 3 months I'd a retest done and my level had increased in 26.7 Needless to say I'm very happy with the result and the service provided."

"Ive been on this for 3 months now can definitely tell the difference. I've also got my partner on it as she lacks energy and shes noticed a difference.

04 · THE RESEARCH

Nine Ingredients. Five Human Studies. Every Dose Explained.

You've read enough supplement claims. Here are the studies instead — who was tested, for how long, at what dose, and how ours compares.

IngredientStudy doseOur dose
Ashwagandha KSM-66®8 weeks · men in resistance training600mg600mg ✓
Himalayan Shilajit90 days · men aged 45–55500mg500mg ✓
Zinc3–6 months · men low in zinc30mg30mg ✓
Vitamin D312 months · men low in vitamin D3,332 IU4,000 IU ✓
Boron1 week · healthy men10mg6mg*

*Boron is dosed for every day, long term — safety limits sit around 10mg a day, so we stay well under the ceiling rather than on it.

01

🌿 Ashwagandha KSM-66® 600mg

The highest-concentration full-spectrum ashwagandha extract available — not the cheap standardised powder in most supplements. Primary clinical action: reducing cortisol. When cortisol drops, testosterone recovers.

The Study

Men new to resistance training took 600mg of KSM-66 a day (300mg twice daily) or a placebo for 8 weeks. Testosterone rose significantly more in the KSM-66 group — alongside bigger gains in strength and muscle size.

02

⛰️ Himalayan Shilajit 500mg

A mineral resin from high-altitude Himalayan rock, naturally rich in fulvic acid. Supports mitochondrial energy production — which is why energy is often the first thing men notice. Not a stimulant buzz, a sustained cellular lift.

The Study

96 men aged 45–55 took 250mg of purified shilajit twice a day, or a placebo, for 90 days. Total testosterone rose 20% and free testosterone 19% — significantly more than placebo.

03

⚡ Zinc + Copper 30mg + 2mg

Training depletes zinc faster than diet replaces it. Zinc is the most common deficiency linked to low testosterone in men who train. Copper maintains mineral balance — the detail most formulas miss.

The Study

Men who were marginally low in zinc took 30mg a day for 3–6 months: average testosterone went from 8.3 to 16.0 nmol/L. In the same paper, young men put on a low-zinc diet saw theirs fall from 39.9 to 10.6 nmol/L. Zinc is also the one ingredient here with an authorised claim: it contributes to the maintenance of normal testosterone levels in the blood.

Study dose 30mg  ·  Our dose 30mg ✓

04

🔩 Boron 6mg

Lowers SHBG — the protein that binds testosterone and locks it away. Less bound T means more free T, the biologically active form your body actually uses. Most men feeling this are low in free T, not just total T. That distinction matters.

The Study

8 healthy men took 10mg of boron a day for a week. Free testosterone rose and oestradiol fell significantly, and SHBG dropped within six hours of the first dose. Small and short — but a clear signal.

Naghii et al., Journal of Trace Elements in Medicine and Biology, 2011

Study dose 10mg  ·  Our dose 6mg — set for daily, long-term use

05

☀️ Vitamin D3 4,000 IU

Technically a hormone, not a vitamin — and in the UK the sun is too weak to make it from October to March. The cells that produce testosterone carry receptors for it directly. Dosed at 4,000 IU, not the token amount in a multivitamin.

The Study

Men low in vitamin D took 3,332 IU a day for a year: total testosterone rose significantly, while the placebo group's didn't. A later trial in men whose vitamin D and testosterone were already normal found no change — it works by fixing a shortfall, not by pushing past normal.

Study dose 3,332 IU  ·  Our dose 4,000 IU ✓

06

🦴 Vitamin K2 (MK-7) 200µg

D3's working partner. D3 helps you absorb calcium; K2 helps direct it into bone rather than letting it build up where it shouldn't. Pairing them is the detail most D3 products skip.

Why It's In

There's no human testosterone study for K2, and we won't pretend there is. It's here because 4,000 IU of D3 every day should come with K2.

07

🛡️ Selenium 200µg

Supports thyroid function — often the missing piece in fatigue that doesn't resolve even when testosterone normalises.

Why It's In

Selenium contributes to normal thyroid function and normal sperm production. No testosterone trial — it's here for the systems around it.

08

🌶️ Piperine 4.75mg

Black pepper extract. Slows the breakdown of everything above in the gut and liver, so more of each dose actually reaches your bloodstream. Small ingredient, big multiplier.

Why It's In

Studied for decades as an absorption aid. A small dose doing a supporting job — no testosterone claim attached.

No fillers. No binders. No additives. 60 capsules. Two per day. Everything on the label earns its place.

Pure Test+ is specifically formulated for men in their 30s and 40s. Testosterone begins declining around 1% per year after 30 — and chronic stress compounds that decline faster than age alone. The men who benefit most aren't waiting until their 50s. They're in their 30s and 40s, doing everything right on paper, and wondering why the results have stopped matching the effort.

No. Pure Test+ works with your body's own production process — it doesn't introduce synthetic hormones or suppress natural output. The formula supports the conditions your body needs to produce testosterone naturally. Nothing in this formula is a synthetic hormone or controlled substance. It's fully compliant with all sporting body regulations.

"I have been taking pure test for almost a month now, noticed some benefits after about day 4 (more energy, increased cognitive function) and now there has been a considerable increase in energy/motivation/training intensity and ability to handle stressful situations. Just signed up to the bi-monthly subs, and also been v impressed with the customer service from Ishan and the team. Highly recommend."
