BPC-157
A closer look at a tendon-healing experiment and the gap between animal findings and human recovery claims.
Included evidence
Animal study
TB-500
Why a trial of thymosin beta-4 eye drops cannot validate injectable TB-500 recovery claims.
Included evidence
Related-molecule trial
GHK-Cu
What a cell-culture experiment can tell us about skin biology—and what it cannot tell us about visible results.
Included evidence
Cell-culture study
Ipamorelin
A human trial exists, but its surgical setting and negative efficacy result matter when assessing wellness claims.
Included evidence
Human randomized trial
Retatrutide
A selected obesity trial shows a weight-loss signal. That finding does not validate products sold outside clinical development.
Included evidence
Human phase 2 trial
Tirzepatide
A selected randomized obesity trial provides clinical evidence, with clear limits on what that evidence says about other products.
Included evidence
Human phase 3 trial
Read the evidence in context
A study is a starting point.
These selected-source editorial reviews explain what the included research found and where its conclusions stop. They are not systematic reviews or medical advice.
Our approach and commercial relationshipsLook at the setting
People, animals, and laboratory findings answer different questions.
Read the limitations
Study design and unanswered questions matter as much as reported results.
