community peptides seems to have dramatically decreased hairloss!

85 upvotes 4 months ago

Peptides like GHK-Cu, BPC-157, and TB-500 have significantly reduced hair loss, with GHK-Cu being particularly effective. The discussion also covers the high cost of these peptides and explores more affordable purchasing options.

community "14" peptides will be able to be legally compounded by US pharmacies soon, according to RFK Jr. podcast comments.

in Product 52 upvotes 6 months ago

Peptides are being discussed for potential hair loss treatments, but most are not proven effective for this purpose. Minoxidil and finasteride are mentioned as more reliable options for hair growth.

community Anyone that has been using peptides and seen hair results?

9 upvotes 8 months ago

Peptides, specifically GHK-Cu, are being considered for hair growth benefits, such as increasing blood flow to the scalp and preventing hair follicle shrinkage. A user reported starting GHK-Cu after hearing it made a friend's hair thicker.

community Had anyone used peptides for help with regrowth?

in Treatment 7 upvotes 1 year ago

Peptides like GHK-Cu are discussed for hair regrowth, with mixed results; some users report no regrowth, while others notice thicker hair. Topical application is common, and proper sourcing and mixing are emphasized.

community Peptides that Stop Hair Loss? | In-depth Literature Review Video

76 upvotes 2 years ago

Peptides like TB500, KPV, GHK-CU, and BPC-157 are overhyped for hair growth with limited proven effectiveness in humans. Combining peptides with delivery methods like iontophoresis and sonophoresis shows promise, but many claims remain unproven.

learn PP405

Did you know PP405 peptides can help protect your follicles from DHT? PP405 is not a peptide and does not block DHT: it is an experimental topical gel from Pelage Pharmaceuticals that inhibits the mitochondrial pyruvate carrier, aimed at waking dormant follicles. Its registered Phase 2 trial (NCT06393452) measured safety and tolerability in 78 adults with pattern hair loss; it is not approved and not for sale.

learn retinol

Can retinol help enhance the absorption of ingredients like minoxidil or peptides? Retinol may enhance absorption of minoxidil and peptides by modifying skin barrier properties.

learn GHK-Cu

Heard alopecia areata leaves scar-like spots? Some peptides are helping those areas regrow hair. Alopecia areata patches usually still have living follicles. Peptides are being studied as a possible add-on, but the evidence is small and early. See a dermatologist for treatment.
