I’m weighing recovery claims against ordinary life on Peptides Blog.

A free morning on the water is the goal in this post, not evidence of a peptide’s effect.

With a modest ambition, I’m opening Peptides Blog: a free morning spent doing something fun. A gentle paddle or a game with friends. No medal required. That’s the sort of life a “recovery” claim brings to mind.

But what did the research actually show? I want to know whether people got back to an activity they enjoyed, and what problems came with treatment. A result from a rat’s knee needs to stay a result from a rat’s knee.

The everyday goal is the part I care about

Amino acids link together to make a peptide. Proteins are built from those same small units, in longer chains. The name tells us about its chemistry. It doesn’t tell us whether something works or where it fits in medical care.

GHK-Cu is one example: a small peptide holding copper. In a study of rats after knee-ligament surgery, it briefly reduced looseness in the knee. The benefit didn’t last. The study couldn’t show a clear difference in walking or in the force needed to break the repaired ligament.

I can see why that experiment interests people. I can’t read it as evidence that a person will recover faster. The photograph here shows the sort of morning I’m talking about; it doesn’t show a treatment result.

I keep skin-care hopes apart from an energy claim

GHK-Cu and NAD+ both attract big claims about ageing. I want to know what changed for a person. A skin-cell experiment can explain an idea without proving a cream works. Higher blood NAD+ can be interesting without proving someone feels better. And despite often sharing the same conversation, NAD+ isn’t a peptide at all.
