Single-compound explainers: origin, chemistry, what the published literature reports and how the material is handled at the bench.

Fifteen amino acids, an unusually stable structure and a very large preclinical literature. Here is what BPC-157 is, and what the published work does and does not show.

Half the confusion around TB-500 comes from treating it as a synonym for thymosin beta-4. It is not. Here is the actual relationship, and why it changes what you should expect from a datasheet.

Most peptides in your body are transcribed from nuclear DNA. MOTS-c is not — and that single fact is why it opened an entire research field.

Tesamorelin is one of the few peptides in this list that has been through full clinical development. That history makes it a useful reference point for everything else.

NAD+ is the odd one out in this series: it is not a peptide at all. It earns its place because almost every metabolic research programme runs into it eventually.

PT-141 is a good reminder that research rarely goes where it intends to. It began as a tanning study and ended somewhere else entirely.

Ipamorelin is usually described as the selective one. Here is what selectivity actually means in receptor terms — and why it is a chemistry claim, not a safety claim.

Four letters separate two very different molecules sold under the same name. If you only remember one thing about CJC-1295, make it this.

Four amino acids and a very large set of claims. Epitalon is a case study in reading a literature critically rather than counting citations.

Of the ten compounds in this series, thymosin alpha-1 has the longest and most conventional research history. It is a useful benchmark for the rest.
