Peptides

Salmon calcitonin has been around long enough that most physicians learned about it before newer bone drugs existed. It was FDA-approved decades ago, once used widely for osteoporosis, and still carries approved indications today. But it also carries something else: a 2014 regulatory narrowing driven by a cancer risk signal and, separately, a long-running question […]

If you have type 1 diabetes, or you love someone who does, you have probably been told to keep a glucagon kit somewhere accessible. Maybe it is in a kitchen drawer, a bedside table, a school nurse's cabinet. What you may be less clear on is what glucagon actually is, how it works, which of

Ozempic and Rybelsus are the same drug — semaglutide — delivered two entirely different ways. One goes under the skin once a week. The other goes through your stomach every morning, after a ritual that requires an empty stomach, a small glass of water, and thirty minutes of nothing else. The active molecule in both

Spend any time researching anti-aging serums and you will encounter two peptide names more than any others: GHK-Cu and Matrixyl. Both are topical peptides. Both have published human trial data behind them. Both are available in affordable over-the-counter formulations. The natural question is whether they are doing different things — or whether one is just

Two peptides are mentioned together so often in injury-recovery communities that some people assume they are the same compound. They are not. BPC-157 and TB-500 have different structures, different primary mechanisms, and different regulatory classifications — yet both occupy the same grey zone: animal data that is genuinely interesting, human data that is nearly absent,

Thymosin alpha-1 is one of the more genuinely interesting peptides in this series — approved in more than 35 countries for hepatitis B and hepatitis C, backed by two decades of peer-reviewed research across multiple independent groups, and yet formally unavailable in the United States. Since 2023, compounding pharmacies operating under Section 503A of the

Every few years the fitness industry rediscovers a compound that sounds tailor-made for the thing bodybuilders want most: burn fat without touching muscle, avoid the diabetogenic side effects of full growth hormone, and do it all with a small synthetic peptide that slips through the regulatory net. HGH Fragment 176-191 — sometimes written Frag 176-191,

AOD-9604 is the textbook case of a peptide that failed its pivotal weight-loss trial more than a decade ago and still gets sold to consumers — partly because Australia briefly reclassified it as a supplement, partly because compounding pharmacies in the GLP-1 shortage era picked it back up. The compound originated at Monash University in

If you have seen Epitalon sold online as a "telomere peptide" that extends human lifespan, the reasonable question to ask is: where did that claim actually come from, and has any independent group confirmed it? The honest answer is that every piece of compelling human evidence for Epitalon comes from a single Russian research group
