Peptides for Women Over 50
Peptides for women over 50 tend to cluster around three research areas: skin and collagen, cellular energy, and reproductive hormone signaling. The three vials below match those areas one for one each with a batch-matched COA.
Why These Three
GHK-Cu is the skin one. This copper-binding tripeptide occurs naturally in human plasma and its level falls hard with age. Loren Pickart’s work tied it to collagen production and tissue remodeling which is why it now shows up in so much skin research.
NAD+ is the energy one. The same 2012 human tissue study that anchors the longevity research applies here: levels drop with age, so labs study what happens when they’re restored.
Kisspeptin is the newest of the three. It sits at the top of the reproductive hormone chain and a 2020 review makes the case for it as a research lever in female hormonal disorders.
Common Questions
Are these third-party tested?
Yes, any vendor we recommend has their vials matched to a signed certificate of analysis from an outside lab. Check the batch number on the label against the COA before it goes anywhere near a research protocol.
What do they cost?
GHK-Cu is $29.99 for a 50mg vial, NAD+ runs $69.99 for 500mg, and kisspeptin is $49.99 for 10mg. Those are current Amino Club prices, checked today.
What about fakes?
GHK-Cu gets copied constantly because skincare demand drives prices up. A blue tint proves nothing about copper content – the COA does.
