A 20:1 pumpkin seed concentrate, rich in β-sitosterol, phytosterols, and cucurbitin — addressing the male DHT-driven hair-loss factors².

Male hair loss mostly comes back to one name — DHT. It is not a disease, but a male hair-loss factor within the body; for some scalps, some follicles, its influence shows more plainly than for others.
Pumpkin seed 20:1 concentrate is the second DHT-defense research base in this formula — set alongside saw palmetto, each carrying its own 24-week human study. Putting two independent research bases in one formula isn't about being louder; it's about making the coordinates clearer.
Pumpkin seed has travelled a long road in the diet of North America. First as seed, as food, as a kitchen staple; only later as research material. The Latin name Cucurbita pepo L. — appearing once is enough.
What we chose is a 20:1 concentrate, standardized on β-sitosterol as its marker. This means the measurable active compounds of twenty parts of raw material are compressed into the density of one part of finished product. A powder, a dry concentrate — not the pumpkin seed oil common on the market.
What should be stated up front — the study most often cited to date (Cho 2014)³ enrolled only 76 men. Female users' response was not validated in that study. This botanical goes into the formula because its research coordinates are clear enough — but which population those coordinates belong to, we'll say up front, not hide in the back.
Aligned to the β-sitosterol standardisation grade of the studied active — the same research-grade standard. On form, the study used pumpkin seed oil; we use a 20:1 dry concentrate — what aligns is the measurable level of β-sitosterol, not the form.
This study ran 24 weeks at a dose of 400 mg of pumpkin seed oil (PSO) per day, with 76 participants — all men with visible signs of hair loss³. The investigators set three directions of observation: clinical assessment, user self-assessment, and an actual count of hair density.

Withania somnifera

Serenoa repens (W. Bartram) Small

Elaeis guineensis Jacq.
All three directions showed improvement. The most often externally cited +40% hair count comes from the last — that is, a gap of about +10% relative to the placebo group (P<0.001).
What this study can tell you — under the conditions of men, 24 weeks, 400 mg of pumpkin seed oil per day, this botanical's research coordinates are clear. What it cannot tell you: female users' response, which this study did not validate; we won't tell you “research has proven this works for you.” Research is just research — not a word more.
After converting the 20:1 concentration ratio back to the equivalent weight of raw material, HairBooster™ sits above the dose used in the Cho 2014 study at both the 1× (maintenance) and 3× (advanced) dose tiers³.
On the question of “is it enough,” the formula-level answer is: it already lands above the dose range used in the published research. The difference in form (the study used oil, we use a dry concentrate) was laid out earlier.
But for some people, this formula isn't suitable — and that has to be said up front, not hidden in the back.
This isn't a warning — it's something this formula is willing to state up front.
Pumpkin seed extract comes in no single form on the market — raw seed powder, cold-pressed oil, ethanol extraction, supercritical CO₂, concentrates at different ratios, different standardisation markers, or none. Our choice is set at a position with research coordinates to align to.
Specification is what stays constant about this raw material:
Each batch's β-sitosterol COA data, the full supplier-qualification file, and the “not this extract” distinguishing description — these belong to the raw-material sub-file, currently in development. They'll be made public once the raw-material sub-file lands.
Pumpkin seed 20:1 concentrate is one of the two specialized botanicals in this formula — set alongside mixed tocotrienols, each carrying its own coordinates under its own research.
Sharing the formula are three flagship botanicals (Annurca apple, ashwagandha, saw palmetto) and thirteen foundational actives (B-vitamins, iodine, selenium, niacinamide, biotin, zinc, vitamin D3, and more).
Five cores, thirteen foundations — designed, not assembled.
