But virtually all of them are overhyped at this point. There are promising results popping up in petri dishes (in vitro studies) and in animal models, but human data is very limited at this point. Norton says hes cautiously optimistic about the true potential of peptides, but given that less than 50% of animal study findings carry over to humans, these compounds really should be vigorously tested in human trials before being marketed to the public. The digestion process may make many of these peptides biologically inert, as digestive enzymes can break them down, though there are some measures that can be taken to protect them during this process
Topical application and microneedling enhance delivery research like the 2025 Kuceki study shows that combining GHK-Cu with microneedling (which creates micro-channels in the scalp) dramatically improves delivery to the target cells and produces measurable regrowth
I would like to see rigorous clinical trials before approval
While there is no known therapy for actually de-aging any organ, including skin, the peptide is thought to exert possible cosmetic benefits on skin that warrant research
Curious about what else GnRH analogues can do
The vas deferens, which transports sperm from the testicles to the urethra, is cut and sealed during the procedure
