It works like a miracle

I've struggled with progressive hair loss for years, even with finasteride and minoxidil. After trying FST-5 for 2 months, I've noticed a huge difference. My hairline is filling in, my crown is thickening, and I don't feel self-conscious taking my hat off anymore. Plus: no brain fog, no dead sex drive. It's been a real confidence booster.

I'd definitely recommend it to anyone dealing with hair loss and doesn't want the side effects of mino or finasteride.

What are peptides?

Peptides are short chains of amino acids—the same building blocks your body uses to create proteins like collagen and keratin. In hair care, they act as signaling molecules that communicate with hair follicles, helping support scalp health, strengthen follicles, and promote healthier hair growth naturally.

Why do peptides work?

Peptides are molecularly small, so they absorb easily into the scalp and reach the hair follicle where it matters. They mimic the body’s natural growth signals, helping wake up weakened follicles and restore a healthier scalp environment. Instead of forcing results, peptides support circulation, nutrient delivery, and longer growth phases—without the harsh side effects of traditional treatments.

Is this suitable for all hair types, ages, genetics?

Absolutely. Because peptides act on the scalp and hair follicles, they’re suitable for all hair types, all ages, and all stages of hair loss. It doesn’t matter if hair thinning is recent or long-term, influenced by genetics, or if you’ve tried other products before—peptides work by supporting the scalp’s natural growth signals from wherever you’re starting.

How to apply the peptide serum

Use 1 full dropper of the peptide serum once per day, ideally after showering. Your scalp can be dry or wet either works. Massage it in for

15–20 seconds, then style and use your usual products as normal. For best results, use consistently every day.

My wife pointed it out first

My hair has been thinning ever since my late 50s, and at 63 I figured it was just part of aging. This peptide serum brought back a level of thickness I thought I’d lost for good. My wife pointed it out first "your hair looks amazing". I'm suprised myself that it worked so well!

Peptides changed every thing for me

I never heard of peptides before. I asked my daughter and she said they are very popular on tiktok. I thought why not try it out. It's been 4 months and the results are amazing! Some of my friends ask if I got a hair transplant. To be honest I have better hair now than when I was 30.

William O.

Highly recommend

I only bought it out of curiosity, but I’m so glad I did. It took a little over 2 months to see a clear difference, but now my hair looks way fuller, my hairline improved a ton. Highly recommend to everyone still on mino or finast. This doesn't have side effects and really worked wonders for me.

Best thing I bought on facebook

Best thing I bought on facebook. I saw an ad somewhere and I clicked. I was pretty sceptic because I never heard of this brand. I asked my kid and they say its pretty well known on Tiktok. I don't use that app. I decided to try it and after 5 weeks I can see a clear difference. Glad I pulled the trigger, will continue and post more results. Thank you guys.

Absolute game changer

The product is amazing. I bought 3 bottles on the sale, have used them all over the last 3 months and the results have been amazing. My fiance literally thinks I got a secret hair transplant. It's an absolute gamechanger. I stocked up on 6 more bottles and got some hair vitamins this time.

Last 6.

I thought would be impossible

I thought it would be impossible to reverse my hair loss. I started loosing hair when I was 19. I tried rogaine, finasteride, all the shampoos and oils but nothing worked. I saw an ad for this and thought why not it's only a couple bucks and they have a 100% guarantee. It's been about 7 months now and for the first time in my life I feel like I have better hair than all my buddies. It's crazy.

The Truth is: Hair Loss isn't Just
About Blocking DHT or Genetics —
it's a Much Deeper Issue.

Here’s What’s Actually Going On Beneath the Skin:

1

DHT triggers cortisol production in scalp tissue

2

Cortisol creates inflammation that blocks amino acids from reaching your hair follicles

3

Traditional treatments block DHT everywhere (destroying your hormones) without restoring scalp tissue and amino acids

Most hair loss treatments only address the surface.

They try to 'block' DHT but they don't reach the root of the issue. Because the issue isn't just DHT — it's what DHT does to your scalp: it blocks amino acids from feeding your hair follicles.

What’s really causing it?

Cortisol production

Inflammatory barrier blocking amino acids

Follicles starving for growth signals

Regular treatments destroying your hormones without fixing the your scalp environment or amino acidic growth signals

That’s why FST-5 Peptide Complex by SwisseOne was created:

Peptides are molecularly small - they break through the inflammatory barrier and deliver amino acid peptides directly to the follicles that need them most.

Peptides feed your hair follicles the exact growth signals they're starving for. Instead of just blocking hormones and destroying sex drive - they fix the root of hair loss.

High Potency Peptides Backed
by 1000s Of Scientific Papers

Strong, potent doses

No Needles

No side-effects

Modern research now confirms this peptide formula contains exactly what hair follicles need to:

Re-activate dormant hair follicles

Your follicles are stuck in sleep mode.

FST-5's molecularly-small peptides reach 4mm deep to restart them.

Restore youthful scalp environment

Reverses years of inflammatory damage and brings your scalp back to the thriving, hair-growing environment you had as a teenager.

Triple growth phase

Signals your follicles to stay in growth mode longer - meaning thicker density, faster regrowth.

No side effects

Works only at the scalp level - doesn't touch your testosterone, sex drive, or mental clarity. Zero brain fog. Zero hormonal destruction. Just results.

Inside each bottle:

Copper Tripeptide-1 (GHK-Cu)

The star player. Molecular weight of just 340 Daltons—small enough to penetrate 4mm deep to your follicle root where the problem actually lives. Calms cortisol-driven inflammation, signals dormant follicles to reactivate, and mimics the exact growth signals your body produced at 17. Clinical studies show 35% hair density increase in 12 weeks.

Palmitoyl Pentapeptide-4

A tissue-repair peptide (molecular weight: 578 Daltons) that penetrates deep to strengthen follicle anchoring. Reduces shedding by up to 46% by reinforcing the connection between your hair shaft and follicle root. Keeps hairs locked in place instead of falling out every time you shower.

Acetyl Hexapeptide-8

Ultra-small peptide (molecular weight: 888 Daltons) that blocks inflammatory pathways triggered by DHT. Protects your follicles from oxidative stress and cortisol damage at the cellular level—stops the inflammation before it can choke out your follicles.

Adenosine

Prolongs the anagen (growth) phase by up to 40%, keeping your follicles in active growth mode longer instead of shedding prematurely. Clinical studies show 5% increase in hair density after 6 months. Prevents premature follicle shutdown.

Niacinamide

Improves scalp microcirculation and oxygen delivery to starving follicles. Strengthens the scalp barrier and reduces inflammation by 40%, creating the optimal environment for peptides to penetrate 4mm deep. Essential cofactor for amino acid delivery.

Panax Ginseng Root Extract

Stimulates dermal papilla cells at the follicle base and increases ATP (cellular energy) production by 60%. Wakes up metabolically-sluggish follicles stuck in resting phase. Traditional Korean medicine powerhouse backed by modern clinical studies showing improved hair thickness.

Polygonum Multiflorum (Fo-Ti Root Extract)

Ancient Chinese remedy that blocks 5-alpha reductase (the enzyme converting testosterone to DHT) locally at the scalp level only—not system-wide. Protects follicles from DHT damage without touching your testosterone, sex drive, or mental clarity.

Biotin

Essential cofactor for keratin synthesis—the structural protein your hair is literally made of. Without biotin, even if peptides signal "GROW," your follicles can't convert amino acids into actual hair strands. Ensures your body has the raw materials to build thick, strong hair.

Expert Advice from Specialized Dermatologist Dr. Marcus Kier, MD

"Peptides are one of the most effective and advanced ways to support hair regrowth today. Unlike traditional treatments that rely on hormonal manipulation or aggressive stimulation, peptides work by restoring natural follicle signaling and scalp health at the cellular level. Their small molecular size allows for better absorption, while their bio-identical nature helps activate growth pathways the scalp already recognizes - making peptides a smarter, safer, and more sustainable approach to hair regrowth"

"The FST-5 Peptide Complex by Keapers™ contains ingredients that are scientifically proven to support hair regrowth, improve scalp circulation, and extend the hair’s growth phase."

Frequently Asked Questions

How is this different from all the other solutions?

Most hair loss products try to force results by blocking hormones or overstimulating the scalp. Peptides work differently. They support the scalp’s natural signaling system, helping restore healthy follicle function instead of disrupting the body’s balance. Because they’re molecularly small and bio-identical, peptides focus on long-term scalp health—without harsh side effects or dependency.

How do I use this product?

Apply one full dropper once per day, preferably after showering. Your scalp can be wet or dry—both are fine. Massage gently into the scalp for 15–20 seconds, then continue using your regular hair products. Use daily and consistently for best results.

Are there any side effects?

No. The peptide serum has no known side effects when used as directed. Peptides are naturally occurring signaling molecules that work with the scalp’s normal biological processes rather than disrupting hormones or body systems.
