PRIMEPROPEL® TESTO CORE™
Men's Daily Vigour Formula — Powder
"It's Not About The Gym. It's About The Day After. And The Day After That."
Why men's vitality isn't a one-day metric — and how nutritional science supports the long game.
There's a version of this conversation that happens in fitness circles, another version that happens at the GP, and a third version that happens quietly, internally, when a man in his 30s, 40s, or 50s notices that something has quietly shifted.
Energy that used to be reliable isn't. Motivation that felt automatic requires more effort. The recovery that used to take one day now takes two.
None of this is dramatic. It's gradual. And it's extremely common.
Testosterone isn't just a gym hormone. It's linked to energy, mood, muscle maintenance, motivation, and overall vitality throughout a man's life. And your body's ability to maintain healthy testosterone levels is directly connected to its nutritional foundation.
When that foundation has gaps — as it does in most UK men, particularly in Vitamin D, Zinc, and B-vitamins — the effects are quiet but cumulative.
CORE-FLOW™ and TESTO CORE™ are built around closing those gaps.
Two Labels. One Formula. Two Audiences.
Before we go any further — a word about the two names.
CORE-FLOW™ and TESTO CORE™ share the same active formula. Same 23 ingredients. Same doses. Same manufacturing standards.
The difference is in how they speak.
- CORE-FLOW™ is positioned for the performance-oriented man — someone who frames their health goals in terms of output, energy, and physical capacity.
- TESTO CORE™ is positioned for the vitality-oriented man — someone who frames their health goals in terms of daily energy, hormone balance, and overall wellbeing.
Same science. Two conversations.
The Formula Architecture
Every daily serving of CORE-FLOW™ / TESTO CORE™ delivers 10,000mg of active formula across two scoops — one in the morning, one in the evening.
Here's what's inside, and why each piece matters.
THE MINERAL CORE
🧪 Zinc — 15mg elemental daily (100% NRV)
Zinc is the single most important mineral in this formula. Not because of marketing — because of the evidence.
✅ Zinc contributes to the maintenance of normal testosterone levels in the blood (Authorised health claim — GB NHC Register)
This is a legally authorised health claim in Great Britain — not a marketing suggestion, not an implication. It is a specific, evidence-based nutritional fact, approved by the GB regulatory system.
Zinc is essential for the enzymatic activity involved in testosterone production. It's also one of the most commonly low minerals in adult men — particularly those who train regularly, because zinc is lost through sweat.
We've included Zinc at full 100% NRV — and in TESTO CORE, we've paired it with:
🧪 Selenium — 100µg daily (TESTO CORE)
✅ Selenium contributes to normal testosterone levels in the blood (Authorised health claim — GB NHC Register)
Selenium works alongside Zinc in supporting the body's natural antioxidant defence system — including within the cells involved in testosterone biosynthesis.
THE VITAMIN FOUNDATION
🧪 Vitamin B6
✅ Vitamin B6 contributes to the regulation of hormonal activity (Authorised health claim — GB NHC Register)
Testosterone doesn't work in isolation — it's part of a broader hormonal signalling system. Vitamin B6 is one of the key nutrients involved in how your body regulates hormonal activity more broadly. This is why it's included here at 100% NRV — not as a filler, but as a functional part of the hormonal support layer.
🧪 Vitamin D3 — 50µg (2,000 IU) daily — From Lichen
✅ Vitamin D3 contributes to normal muscle function ✅ Vitamin D3 contributes to the normal function of the immune system (Authorised health claims — GB NHC Register)
Here's a number that matters in the UK context: approximately 1 in 6 UK adults has Vitamin D levels below the minimum recommended threshold. Not just in winter. Year-round, for many people.
Vitamin D is synthesised in the skin through sunlight exposure — and in the UK, the sunlight angle from October to April is insufficient for the body to make any Vitamin D at all, regardless of time spent outdoors.
For men focused on muscle function and physical performance, Vitamin D deficiency is one of the most impactful and most overlooked nutritional gaps in British men's health.
We've included Vitamin D3 at 50µg (2,000 IU) — sourced from lichen, making it fully vegan. That's 250% of the UK NRV, because maintaining adequate Vitamin D status in the UK context requires more than a token inclusion.
🧪 Vitamin C — 80mg (100% NRV)
✅ Vitamin C contributes to the protection of cells from oxidative stress (Authorised health claim — GB NHC Register)
Physical training generates oxidative stress as a normal metabolic byproduct. Vitamin C is one of the body's primary water-soluble antioxidants — supporting protection of cells from that oxidative load.
THE AMINO ACID CORE
🧪 L-Citrulline — 3,500mg daily
🧪 L-Arginine — 500mg daily
Combined amino acid dose: 4,000mg per day.
L-Citrulline and L-Arginine are two of the most widely researched amino acids in sports and performance nutrition. They are included in this formula as part of the amino acid complex at genuinely impactful doses.
Important note on claims: There are currently no UK-authorised health claims for L-Citrulline or L-Arginine. We include them as part of our formula's amino acid foundation — at doses consistent with those used in sports nutrition research — without making specific functional claims beyond what is legally authorised. You can research these ingredients independently and draw your own conclusions.
THE BOTANICAL COMPLEX
This is where the formula extends beyond pure micronutrient science into the world of traditional plant-based wellness — and where we are clear about what we're claiming and what we're not.
The following six botanicals are included in CORE-FLOW™ / TESTO CORE™. None of them carry UK-authorised health claims in this formula. They are included because they each have long, well-documented histories of use in traditional wellness systems across different cultures:
🌿 Korean Red Ginseng — 600mg daily
(Panax ginseng — traditional use: energy, vitality)
One of the most extensively studied adaptogens in the world, used in Korean and East Asian wellness traditions for centuries. Included at a full 600mg daily dose — a level consistent with traditional usage.
🌿 Fenugreek Seed Extract — 600mg daily
(Trigonella foenum-graecum)
Fenugreek is one of the most widely used plants in men's wellness supplements globally — traditionally consumed across South Asian, Middle Eastern, and Mediterranean cultures for centuries. Included at 600mg daily.
🌿 Ashwagandha Root — 500mg daily
(Withania somnifera — KSM-66® equivalent spec)
Ashwagandha is classified as an adaptogen — a category of plants traditionally used to support the body's response to physical and psychological stress. Its roots have been central to Ayurvedic practice for over 3,000 years. Included at 500mg daily.
🌿 Shilajit Purified — 500mg daily
(Himalayan mineral resin)
Shilajit is a naturally occurring substance found in Himalayan rock formations — formed over centuries from decomposed plant matter. Used in Ayurvedic medicine for millennia. Included at 500mg daily of purified form.
🌿 Pine Bark Extract — 330mg daily
(Pinus maritima, OPCs ≥95%)
Pine Bark Extract — standardised to ≥95% OPCs (oligomeric proanthocyanidins) — is a plant-derived antioxidant complex included at 330mg daily.
🌿 Black Maca Root — 190mg daily
(Lepidium meyenii — Black variety)
Maca root has been cultivated in the Peruvian Andes for over 2,000 years — used traditionally by indigenous communities for energy and vitality. The black variety is included here, selected for its specific traditional profile.
🧪 CoQ10 Ubiquinone — 300mg daily
Coenzyme Q10 is a naturally occurring compound present in every cell of the human body — playing a central role in cellular energy production (specifically the mitochondrial electron transport chain).
300mg of CoQ10 per day is a genuinely high dose — included as part of the energy and vitality layer of the formula. Micronised to <10µm for enhanced absorption.
There are no UK-authorised health claims for CoQ10. It is included as a premium nutritional compound with an extensive body of published research you can explore independently.
Why Powder — Not Capsules
Do the maths with us:
| Ingredient | Daily dose |
|---|---|
| L-Citrulline | 3,500mg |
| L-Arginine | 500mg |
| Korean Red Ginseng | 600mg |
| Fenugreek Extract | 600mg |
| Ashwagandha | 500mg |
| Shilajit | 500mg |
| Pine Bark Extract | 330mg |
| CoQ10 | 300mg |
| Black Maca | 190mg |
| Total botanicals + amino acids | ~7,020mg |
To deliver 7,000mg+ per day in capsule form, you'd need 14–18 large capsules daily. That's not a supplement routine — that's a part-time job.
Two scoops of powder delivers everything. No pill fatigue. No counting. No compromise on dose.
The Daily Routine
Serving size: 1 scoop = 5g Daily dose: 2 scoops (10g) — split morning and evening Supply: 60 scoops / 30-day supply Flavour: Natural Strawberry Format: Fully vegan | No artificial colours or flavours
Morning scoop: Mix 1 scoop into 300–400ml of cold water. Stir or shake well. Drink immediately.
Evening scoop: Repeat. Consistent daily use over weeks is where nutritional support delivers its most meaningful results.
What We're Claiming — And What We're Not
We want to be direct about this, because in the men's supplement category, the line between food supplement and medicine is often blurred — deliberately — by brands that make claims they're not legally permitted to make.
CORE-FLOW™ / TESTO CORE™ is a food supplement. It is not a medicine. It does not treat, cure, or prevent any medical condition.
What it does — with full legal authorisation:
- ✅ Support normal testosterone levels in the blood (Zinc)
- ✅ Support regulation of hormonal activity (Vitamin B6)
- ✅ Contribute to normal muscle function (Vitamin D3)
- ✅ Protect cells from oxidative stress (Vitamin C)
- ✅ Support normal muscle function (Magnesium)
- ✅ Contribute to normal energy-yielding metabolism (B-vitamins)
What it includes without authorised claims — but with transparency:
- 🌿 A traditional botanical complex with centuries of use in wellness traditions
- 🧪 A high-dose amino acid core consistent with sports nutrition research
- 🧪 300mg CoQ10 as a premium cellular energy compound
If you want a men's supplement that makes dramatic promises it can't legally back up — this isn't it.
If you want a formula built on the largest daily dose we could engineer into a powder format, anchored by legally authorised nutritional science, rounded out with traditional botanicals at meaningful doses — this is it.
Two Scoops. Morning and Evening. One Clear Daily Routine.
No pill clutter. No underdosed formulas hidden inside a capsule. No promises we can't keep.
Just 23 active ingredients, 10,000mg a day, built for the demands of a full life — not just the gym.
