WHAT PEOPLE SAY
READ THREADS ON REDDIT ↗COMMUNITY SENTIMENT
60% positive
“Did an experiment with 5g/day for two months. My fingernails grew 30% faster over 4 weeks vs another 4 weeks without any. My hair also grew faster. Subjectively, I had a wound heal pretty quickly that surprised me. As far as the joints and vascular tissue I don't know. I assume these are benefiting from collagen but I don't have a way to measure directly.”
U/JAICOBB ↗“Protein, proven to have an effect on the body. Creatine the single most studied supplement on the planet with positive effects. And collagen which is a hard sell and may or.may not have benefits”
U/NO_MEDIUM_8796 ↗“Have had problems with tendons in both elbows for years due to gym/lifting. Tried bpc. Helped a bit. Added collagen. No longer have any issues. Occasional flare up but I recover in days instead weeks”

Add context that might help others — skin type, conditions like PCOS, what you'd tried before. The more specific, the more useful.
