Trending
What’s trending in peptides.
The peptide products women are actually searching for and buying, ranked by real-world demand — then graded on the evidence.
Evidence grade — our read, independent of the ranking
- FDA-approvedFDA-approved for the use in question.
- Some evidenceReal human data, though usually modest.
- Thin evidenceSmall, preliminary, or largely animal data.
- Mostly hypePopular well beyond what the evidence supports.
- Claim invertedThe evidence points the opposite way from the marketing.

Semaglutide (Ozempic / Wegovy)
Metabolic · GLP-1FDA-approvedWhy it’s trending: The best-selling drug franchise in the world (~$48B) and the most-searched peptide by far — ~1.5M US searches a month. Oral Wegovy launched January 2026.
Our read: FDA-approved for weight management and type 2 diabetes. The women's questions that matter most — muscle and bone loss, hair shedding, pregnancy — are the ones the ads skip.

Tirzepatide (Mounjaro / Zepbound)
Metabolic · GLP-1FDA-approvedWhy it’s trending: The fastest-growing GLP-1 and second most-searched peptide (~823K US searches a month), with weight outcomes that often run ahead of semaglutide.
Our read: FDA-approved and effective, but not yet in our catalog. Same muscle-, bone-, and hair-loss cautions apply — the hair-loss signal is notably higher in women.

BPC-157
RecoveryThin evidenceWhy it’s trending: The research peptide most people start with, and the most-searched of the non-GLP-1 peptides (~74K US searches a month), marketed for joint, tendon, and gut repair.
Our read: Animal data is genuinely interesting; human evidence is roughly three small studies. Removed from FDA Category 2 in April 2026 and recommended for the 503A list at the July PCAC review — but that's advisory only and it can't yet be legally dispensed on that basis.

Copper peptide serums (GHK-Cu)
Skin · CosmeticSome evidenceWhy it’s trending: The fastest-rising cosmetic peptide. Copper-peptide serums like The Ordinary Multi-Peptide + Copper are beauty-aisle bestsellers.
Our read: The best-supported topical peptide for skin — multiple human studies for firmness and hydration — but results are subtle and take months. Injectable forms are a separate, more-regulated story.

Matrixyl / palmitoyl-peptide serums
Skin · CosmeticThin evidenceWhy it’s trending: The default 'anti-wrinkle peptide' in most serums on the shelf, from budget to prestige.
Our read: Modest, real, and oversold. Small, often manufacturer-funded studies show mild fine-line improvement — and most cosmetic peptides struggle to even penetrate the skin barrier.

"GLP-1 for hair" add-ons
Marketing bundleClaim invertedWhy it’s trending: A fast-spreading Instagram/DTC pitch — pairing a GLP-1 program with a hair-growth 'support' product.
Our read: The evidence runs the other way: GLP-1s are associated with hair loss, and the risk is higher in women (about 7% vs under 1% in men in tirzepatide trials). A seller pairing the two is worth a hard look.

CJC-1295 + Ipamorelin (GH-axis stack)
Hormone · GH-axisThin evidenceWhy it’s trending: The classic growth-hormone-axis pairing sold by peptide clinics for body composition, sleep, and recovery.
Our read: Small, short human studies. CJC-1295 in particular carries a more cautious regulatory status — don't let a clinic treat it as interchangeable with ipamorelin or sermorelin.

Longevity peptides (NAD+, MOTS-c, epithalon)
LongevityMostly hypeWhy it’s trending: The fastest-rising category by growth rate, riding the broader longevity wave — heavily marketed, thinly studied.
Our read: Mechanistically interesting, but human evidence for the anti-aging claims is preliminary at best. Popularity here is running well ahead of the data.
How we rank
Demand, not endorsement. Ranking reflects real-world popularity as of September 2026 — US search volume, published sales and market data, and how heavily a product is advertised to women. A high rank means many people are looking; it says nothing about whether they should be.
The grade is separate. Each grade is our independent read of the evidence — from FDA-approved down to mostly hype — decided the same way as our peptide entries. When popularity and evidence disagree, we say so plainly.
