PD-5 Complex™ Peptide Serum
The first topical peptide protocol formulated specifically for GLP-1-related hair loss. During treatment and after.
"My brush was getting full one stroke earlier each week. By month three on my medication I was scared to even touch my hair. Six weeks on this serum — my ponytail feels like my ponytail again."

Why GLP-1 Medications Cause Hair Loss
It's not one thing going wrong. It's three biological events happening at once — and none of the solutions your doctor can offer were designed for this.
Metabolic Shock
When you lose weight rapidly, your body goes into conservation mode. It diverts nutrients away from "non-essential" functions — like hair growth — to protect vital organs.
Telogen Shift
Up to 50% of your follicles can enter resting phase at once. 2-4 months later, they all release. That's why shedding often starts months after you begin medication — or continues after you've stopped.
Nutrient Depletion
Your appetite is suppressed. You're eating less. The zinc, iron, biotin, and vitamin D your follicles need to restart growth simply aren't arriving. Oral supplements go through the gut — and even less gets absorbed.
If you're 2-6 months into your medication and noticing more hair in the brush, on your pillow, or in the shower — you're in the shedding window. The time to act is before the peak.
The PD-5 Complex addresses all three — directly at the scalp. Not through the gut. Not through the bloodstream. Where the damage is actually happening.
Biotin goes through your gut and hopes to reach your follicles. Hair vitamins were built for genetic thinning. Minoxidil was built for pattern baldness. None of them address what's actually happening during GLP-1 shedding.

None of These Were Designed for GLP-1 Hair Loss
| The Problem | PD-5 Complex™ | |
|---|---|---|
| Biotin ($10-25/mo) | ✕ Goes through gut, useless unless deficient | ✓ Delivers peptides directly to scalp |
| Hair Gummies ($15-35/mo) | ✕ Sugar + vitamins. No clinical evidence for TE | ✓ 5 peptides backed by peer-reviewed RCTs |
| Nutrafol ($79-88/mo) | ✕ Oral. Designed for genetic thinning | ✓ Topical. Built for GLP-1 shedding window |
| Collagen ($20-40/mo) | ✕ Marginal at best, no evidence for TE | ✓ Saw Palmetto: 22% shedding reduction |
| Minoxidil ($15-40/mo) | ✕ Works, but must use forever. Side effects. | ✓ No prescription, no forever commitment |
| "Just wait it out" | ✕ The only answer doctors have | ✓ A protocol. For the 3-9 month window. |
Biotin + Nutrafol + collagen = $244/mo. The PD-5 Complex: $1.30/day.
What Women Are Saying
Stopped checking the drain. Week 6.
"My shower drain used to give me anxiety. Every single morning. After about six weeks on the serum, I stopped checking. Not because I was forcing myself — because there was nothing to check."✓ Verified Purchase
Baby hairs at month three.
"I spent over $400 on supplements that did absolutely nothing. Biotin, collagen, that expensive hair vitamin everyone talks about. This is the first thing that actually goes on my scalp where the problem is. I saw baby hairs at month three."✓ Verified Purchase
Kept the weight loss. Kept my hair.
"I was this close to stopping my medication. The weight loss changed my life but my hair was falling out in clumps. My friend found this and I figured what's one more thing to try. I'm glad I did."✓ Verified Purchase
Hairstylist noticed at month 4.
"Month one: skeptical. Month two: less shedding. Month three: baby hairs. Month four: my hairstylist asked what I changed. That's all the proof I needed."✓ Verified Purchase
Finally something that goes where it matters.
"I spent months swallowing biotin pills and nothing changed. The logic of putting it directly on your scalp just made sense. Six weeks in and the shedding has noticeably slowed."✓ Verified Purchase
Wish I'd started sooner.
"My only regret is not finding this 6 months ago when the shedding started. I'm at month two now and the drain is finally clear. My part line is still wider than I'd like but I see new growth coming in."✓ Verified Purchase
"Supporting the follicle environment during the GLP-1 shedding window makes physiological sense. A topical approach that delivers peptides directly to the scalp addresses the problem where it's actually happening."

Board-Certified DermatologistFrequently Asked Questions
"Is this safe to use with my medication?"
Yes. The PD-5 Complex is a topical cosmetic serum applied to your scalp. It does not interact with GLP-1 medications, oral supplements, or any prescription drugs. Always consult your healthcare provider if you have specific concerns.
"How long until I see results?"
Most women notice reduced shedding within 4-6 weeks. Visible new growth typically appears at month 2-3. Consistent use for 90 days is recommended for best results.
"Is weight-loss-related hair loss permanent?"
No. Telogen effluvium from rapid weight loss is temporary and reversible in the vast majority of cases. Supporting your follicles during the shedding window may help reduce the severity and duration.
"How is this different from Nutrafol or Viviscal?"
Those are oral supplements designed for genetic hair thinning — a completely different condition. GLP-1 hair loss is a different biological event. The PD-5 Complex is the first topical serum formulated specifically for this. Applied directly to your scalp, not through your gut. Different problem, different delivery, different protocol.
"Do I have to use this forever?"
No. This is designed to support your hair during the shedding window. Most shedding occurs during months 3-12 of rapid weight loss. Once your weight stabilizes and your hair recovers, you can discontinue.
"What if it doesn't work for me?"
We offer a 90-Day Consistency Guarantee. Use it daily for 90 days. If you don't notice a difference, contact us for a full refund. No questions.
