“Really?” can be a dismissal. I prefer it as the beginning of a longer conversation with an interesting result.

## Why this review exists

Really Research Review is a personal review of published research on NAD+, MOTS-c, GHK-Cu and semaglutide. The companions of a much-repeated result interest me: the comparison group, the other ingredient, the unchanged measurement.

A placebo group with a [rise in hair count](https://pmc.ncbi.nlm.nih.gov/articles/PMC4969472/) seems a fine place to begin. It complicates the story without emptying it of interest. The active mixture did better, and the unexplained share of credit between its ingredients gives the research somewhere to go.

Nothing on Really Research Review constitutes personal medical advice. These pages cannot evaluate an illness, weigh someone’s medical history or decide a treatment. There is no medical service or product checkout at Really Research Review.

## Conviction and doubt

My admiration is quite uneven. Putting [semaglutide beside another medicine](https://pubmed.ncbi.nlm.nih.gov/40353578/) in a direct weight comparison is a choice I admire. I question rejuvenation claims when a [review of human NAD+ trials](https://pubmed.ncbi.nlm.nih.gov/41083806/) finds limited efficacy and sparse tissue data.

Discarding a selective result for disappointing a larger hope strikes me as wasteful. An improvement in [muscle insulin sensitivity with unchanged body composition and HbA1c](https://pubmed.ncbi.nlm.nih.gov/33888596/) deserves a careful account of both findings. The unchanged measures make the improvement more specific.

None of those judgements requires dismissing laboratory work. Cell and animal experiments can expose a mechanism with remarkable precision. The question of a useful, safe treatment in people asks for additional evidence.

## When an account needs correcting

A mixed formulation credited to a lone ingredient, a human tissue experiment described as treatment in living people, a combined outcome stripped of its components: each would materially change the claim. Those are the corrections I welcome.
