KLEEN BIO SYN-X7

Not a booster. A binder. The first formula built to clear microplastic from the tissue that makes your testosterone.

01 What's inside.
Activated Charcoal
500 mg
Binds to microplastics, heavy metals, and synthetic compounds in the digestive tract before they recirculate through the bloodstream. Medical-grade. Not the stuff in your face wash.
Chlorophyllin
300 mg
Derived from chlorophyll. Binds to lipid-soluble toxins at a cellular level — the class of compounds microplastics fall into. Clinical literature shows significant reduction in systemic toxin load.
Psyllium Husk
2 g
The escort. Creates the bulk matrix that carries bound compounds out of the body before they re-absorb. Without a carrier, binding does nothing.
Zinc  /  Selenium
15 mg · 100 mcg
Reinforces the intestinal barrier that microplastics exploit to enter your bloodstream. Without this layer of protection, cleared particles can simply re-enter circulation.
02 The science.
Two studies. Both peer-reviewed. Neither paid for by us.
University of New Mexico · 2024 · Toxicological Sciences
Microplastics in testicular tissue
PMID 38745431

Microplastics were detected in testicular tissue in 100% of human samples examined. Samples with higher microplastic concentration correlated with lower testosterone output.

Nanjing University · 2022
Microplastics in Leydig cells
PMID 35177090

Microplastics were shown to accumulate specifically in Leydig cells — the cells directly responsible for testosterone biosynthesis — physically disrupting their function.

These are peer-reviewed studies. Publicly available. We didn't write them. We built SYN-X7 around what they found. The mechanism isn't theoretical. The blockage is documented. The formula targets it directly.
03 How to take it.
One serving per day with 16oz of water. Morning is ideal — before food if possible.
Weeks 01 — 02
The binding phase.

Activated charcoal and chlorophyllin begin capturing and flagging compounds for removal. Most men notice subtle cognitive shifts — clearer mornings, slightly less afternoon fog. Don't look for dramatic changes yet.

Weeks 03 — 04
The clearing phase.

Psyllium husk escorts the bound load out. This is where men start reporting the hormonal shift — drive returning, energy stabilising, mood levelling out.

Weeks 05 — 12
The reset phase.

Zinc and selenium signal Leydig cell reactivation. This is the phase most supplements never reach — because men give up at week two expecting a stimulant effect. SYN-X7 is not a stimulant. It's a system.

One rule

Don't take SYN-X7 within two hours of other medications or supplements. Activated charcoal binds indiscriminately — give it a window to work on what matters.

04 Frequently asked questions.
Is this just another testosterone booster?
No. SYN-X7 contains zero testosterone precursors, herbal stimulants, or "T-boosting" compounds. The mechanism is microplastic removal — not supplementation. That's the entire point. Boosters push harder on a blocked system. SYN-X7 removes the block.
Do I need to change my diet or lifestyle?
No. The bundle bonuses are designed to accelerate results — not gatekeep them. SYN-X7 works on its own. The protocols make it work faster and help stop re-exposure. Use them if you want to maximise the 90 days. Don't use them if you just want to run the supplement.
Is it safe to take with other supplements?
Yes — with one exception. Don't take SYN-X7 within two hours of other supplements or medications. Activated charcoal binds broadly. Give it a dedicated window.
Why haven't I heard of this before?
Because the supplement industry is built on selling you more testosterone, not on removing what's blocking it. A removal product doesn't fit the "boost" narrative that's been profitable for thirty years. The research on microplastics in testicular tissue has only recently become impossible to ignore.

what's in the bundle

Store in a cool, dry place away from direct sunlight.

Keep the bottle tightly closed to maintain freshness.

Best used within 12 months after opening.

You're not low.
Something's
in the way.

You train hard, eat clean, and you've run through the whole shelf of supplements— and the needle barely moves. The issue was never the missing testosterone. It's what's sitting in the tissue that makes it.

Subject SUBJECT

Why boosters
don't fix this.

Microplastics have been documented inside the human body — including the exact tissue responsible for producing testosterone.

Boosters push production harder while the interference stays exactly where it is. SYN-X7 does the opposite — it supports your body's own clearance of microplastic, so the tissue can work without something in the way.

What's
inside.

Modified Citrus Pectin 01 Citrus pectin
Ingredient 01 / 04

Modified Citrus Pectin.

Citrus × paradisi

Soluble fiber studied for binding particles in circulation so they're carried toward elimination. The first action of the protocol — meeting the interference at the level of the bloodstream.

STEP 01/Grabs the plastic in your blood
Ingredient 02 / 04

Chlorella.

Chlorella vulgaris

A freshwater algae used in binding protocols. Holds onto what's pulled from the bloodstream at the gut level — keeping it from re-entering circulation as it moves through.

STEP 02/Traps it in your gut
Chlorella 02 Chlorella
Psyllium Husk 03 Psyllium husk
Ingredient 03 / 04

Psyllium Husk.

Plantago ovata

The mechanical sweep. Moves bound material out of the body instead of letting it recirculate — the closing motion of the protocol's clearance phase.

STEP 03/Sweeps it out
Ingredient 04 / 04

Zinc.

Element · Zn · 30

An essential mineral for normal testosterone production and tissue recovery. The rebuild step — what restores the system once the interference is no longer in the way.

Week By Week. 
What To Expect.

WEEK 2

The Flush Begins

SYN-X7 binds and begins clearing. Most men notice subtle cognitive shifts — less afternoon brain fog, slightly sharper mornings. Don't look for dramatic changes here. The system is clearing.

WEEK 2

The Fog Lifts

Men report the clearest sign in week two: mental clarity returns first. The brain contains some of the highest microplastic concentrations in the body. When clearance begins systemically, cognition shifts first.

WEEK 3

Drive Returns

This is where men start noticing the hormonal shift. Morning energy. Competitive instinct returning. Desire — physical and psychological — coming back without effort.

WEEK 4

The Baseline

You're not "boosted." You're restored. This is the difference between a stimulant effect and a biological reset. What you feel in week four is what your body was capable of before the plastic accumulated.

This is what 1980s baseline biology feels like.
