10mThe collagen powder in a grocery store and the vial labeled "research use only" share one word and almost nothing else. This guide explains what each one is, how each is regulated, what the human evidence shows for collagen on skin, joints and bone, and where the copper peptide GHK-Cu fits.
12mA goal-by-goal map of the peptides people ask about most, scored on human evidence and regulatory status. The only ones with strong evidence are approved drugs; most of the rest are animal data. No vendors, no dosing.
11mNo peptide is FDA-approved for building muscle in healthy adults. Here is what the human trials actually measured for growth hormone secretagogues, IGF-1 analogs, MOTS-c and the GLP-1 drugs, where each sits on the evidence ladder, and what regulators and anti-doping rules say.
10mPeptides are short chains of amino acids that act as messengers in the body. Some are FDA-approved medicines like insulin and the GLP-1 drugs. Many sold online are unapproved research chemicals. Here's the plain-language version.
7mWomen have unique considerations with peptides, from hormones and cycle changes to muscle retention, recovery, skin health, and tracking.
8mConfused about peptide compounding categories? This guide breaks down 503a compounding pharmacies, 503b outsourcing facilities, and why “research use only” is not a consumer pathway PeptIQ endorses.
12mRetatrutide is Lilly's investigational GIP/GLP-1/glucagon triple agonist. This hub covers what it is, what the trials actually reported about dosing and weight loss, how vial math works, where approval stands, and links to every retatrutide guide on PeptIQ.io.
