We're thrilled to announce Superpower x Sequoia.
Sequoia has launched Superpower for its own 800+ employees. And Superpower is now available to eligible employers across Sequoia's ecosystem of 2,500+ companies.
Proactive healthcare, now reaching millions more people.
ANNOUNCING: Sequoia has launched Superpower for its own 800+ employees.
And through our new partnership, Superpower is now available to eligible employers across Sequoia's ecosystem of more than 2,500 companies.
Members get:
- Comprehensive biomarker testing
- A longitudinal view of their health
- Personalized recommendations
- 24/7 Health AI and clinical support
For employers, that means moving healthcare further upstream, before risk becomes a diagnosis or an expensive claim.
As we all know, healthcare has a timing problem. We start paying serious attention to our health only when something goes wrong.
We built Superpower around a different idea:
Give people an extensive understanding of their health earlier – then help them continuously act on it.
Eligible Sequoia clients that want to launch before the end of the year get a special opportunity to get started.
This is another step toward making proactive healthcare available to millions more people.
We're just getting started.

This is why the formula matters so much with topical GHK-Cu.
A serum can contain the right peptide, but if it doesn’t help enough of it cross the skin barrier, very little may reach the tissue underneath.
It can look great on paper and still underperform in real use.

Still, the biology behind it looks promising.
If researchers can turn that repair signal into safe, reliable treatments, GHK-Cu could end up having applications far beyond skincare.

There’s an important marker for the hair and skin story, and that is ferritin.
Ferritin shows how much iron your body has stored.
When it gets too low, hair shedding can increase.
Low iron stores can also show up as dull skin and poor nail quality.

GHK-Cu may work on some of the repair pathways behind appearance, but it does nothing to rebuild low iron stores.
So if you’re dealing with hair shedding or changes in your skin and nails, ferritin is one of the first markers worth checking.

There's a peptide in your blood that drops by more than half by age 60.
It's tied to collagen, hair growth, and wound healing.
In trials, restoring it closed diabetic wounds 3x faster and improved wrinkles, firmness and skin density in 12 weeks.
Here's the breakdown: (1/17)

Another tissue that heavily depends on healthy skin and repair signals is hair follicles.
Hair follicles constantly cycle through growth, rest and shedding.
This means that GHK-Cu could potentially influence hair growth as well.

In one 12-week study of 67 women, topical GHK-Cu improved:
- wrinkle
- skin density
- thickness
- firmness
- clarity
Other small studies reported similar results.

Aging skin was an obvious place to look next.
Skin depends heavily on collagen and elastin for its strength and elasticity.
So researchers began testing whether GHK-Cu could influence those same repair processes in aging and damaged skin.

The GHK-Cu wounds closed 3 times faster and were almost completely healed, compared with about 61% closure in the control group.
Infections were also much lower: 7% vs. 34%.

That eventually led to important human testing.
181 people with diabetic foot ulcers entered a multicenter randomized study.
Everyone received intensive wound care.
Some also received a topical gel containing GHK-Cu.

So they tested that idea in living wounds.
In a 1993 rat study, GHK-Cu increased:
- collagen
- DNA
- total protein
- other parts of the new tissue forming inside wounds
Collagen synthesis increased about twice as much as non-collagen proteins.

A lot of that rebuilding is handled by cells called fibroblasts.
They make collagen and other material that gives tissue its structure.
Researchers found GHK-Cu could increase collagen production and change how old and damaged tissue is broken down and rebuilt.

GHK is made from only three amino acids.
It also binds copper extremely tightly. Once copper attaches, it forms GHK-Cu.
This gave researchers a possible mechanism, since copper is involved in collagen formation and tissue repair.

The peptide in question is called GHK.
It was first isolated from human plasma in 1973 after researchers traced an activity in blood that made older liver tissue produce proteins more like younger tissue.
That gave them the first clue that GHK was involved in repair.

Researchers were also looking beyond erections.
Sexual function includes desire, arousal and motivation, all of which involve the brain.
This meant that melanocortin signaling could possibly influence those as well.

Sexual dysfunction may not need to be treated as one single problem.
Treatments could eventually become much more precise about whether they target desire, arousal, or the physical response itself.
