The compound library
What it is, and what to ask
One page per compound — the plain description, what the format changes, and the questions worth putting to any supplier including us. Not what it does: for the science, each page links to Dr. Schuster's field guide. This is the buyer's and clinician's lens, and it is the one nobody in this category writes down.
Tissue repair & recovery
BPC-157
Body Protection Compound 157
A synthetic peptide that everyone in this space has heard of and few can describe precisely. Here is what it is, and what to ask before ordering it.
TB-500
Thymosin Beta-4
Often sold alongside BPC-157 and often confused with it. A different molecule, a different origin, and the same questions worth asking.
Anti-aging & longevity
GHK-Cu
Copper Peptide
A copper-bound tripeptide that turns up in skincare and in vials, which are not the same product. What the difference is, and what to ask.
MOTS-c
Mitochondrial-derived peptide
A mitochondrial-derived peptide with a genuinely interesting origin story and the same supply questions as everything else here.
Epithalon
Epitalon
A four-amino-acid peptide with a long history in the longevity conversation and very little settled about it. What is known, and what to ask.
Growth hormone & body composition
CJC-1295 + Ipamorelin
CJC-1295 with Ipamorelin
Two peptides almost always sold as a pair, which raises a documentation question a single compound does not.
Tesamorelin
Tesamorelin acetate
One of the few peptides in this category with an approved drug counterpart — which makes the approval question sharper, not simpler.
Sermorelin
Sermorelin acetate
A long-standing peptide with a history in compounding pharmacy, which shapes the questions worth asking about any given vial.
Cognitive & wellness
Semax
Semax peptide
A peptide from a different research lineage than most of this list, which is itself worth understanding before ordering.
DSIP
Delta sleep-inducing peptide
A peptide whose name makes a claim its evidence does not fully support. What it is, and why the name is the thing to be careful about.
Sexual health & vitality
Immune & other actives
NAD+
Nicotinamide adenine dinucleotide
One of the most-searched names in the longevity world, sold as an IV, an injection and a precursor pill. What the molecule is, and why the format is most of the conversation.
Glutathione
GSH
A tripeptide the body makes on its own, sold as an injectable and an IV. What it is, and why 'the body already makes it' is not the end of the conversation.
Thymosin Alpha-1
Thymosin α1
The third of the confusingly-similar thymosin names, and a distinct molecule from the other two. What it is, and how to keep them straight.
Ordering for a practice?
There is a version of this written for clinics — the same plain answers, plus what to ask before you commit to anything, and who to talk to when a question goes past what a page can settle.
