Cagrilintide: The Amylin Analogue, and What Its Published Trials Actually Report
Cagrilintide is an engineered amylin analogue with a genuinely interesting design story: native amylin forms amyloid fibrils so readily that a long-acting version was considered impractical for years. Here is how that was solved, and what the published trials report — including the one that missed its endpoint.

Bacteriostatic Water: The $20 Vial That Decides Whether Your Peptide Survives
Every lyophilised peptide you buy is inert powder until it is reconstituted — and what you reconstitute it with determines whether it lasts a week or a month. Sterile water is not the same thing. Here is why, and why it belongs in every order.
PT-141 (Bremelanotide): The Melanocortin Peptide That Went the Whole Way Through Approval
Most research peptides never reach a regulator. Bremelanotide did — it is an FDA-approved drug. Here is the mechanism, what separates it from every other compound in this category, and the distinction that matters when you buy research-grade material.
KPV: Three Amino Acids, and the Reason Researchers Keep Coming Back to Them
KPV is the smallest compound in this catalogue that anyone studies seriously — a three-residue fragment of alpha-MSH that retains anti-inflammatory activity without the pigmentation effects of the parent hormone. Here is why that matters, and how to buy it without guessing.
GHRP-6: The Old Secretagogue That Newer Peptides Still Get Compared To
GHRP-6 has been in the literature since the 1980s, which in this field makes it ancient — and that is exactly why it is still useful. Here is what separates it from ipamorelin and the GHRH analogues, and what to check before you buy.
IGF-1 vs IGF-1 LR3: The Two Are Not Interchangeable, and People Order the Wrong One Constantly
Native IGF-1 and the LR3 analogue are treated as the same product across most of the market. They are structurally different molecules with different binding-protein behaviour and different half-lives. If your protocol specifies one, the other will not do.
CJC-1295 With DAC vs No DAC: One Chemical Group, Two Completely Different Compounds
The most commonly mis-ordered peptide in Canada is CJC-1295, because two products share the name and differ by a single modification that changes the half-life from minutes to days. Here is how to tell them apart before you order the wrong one.
ARA-290 (Cibinetide): The EPO Fragment That Left the Blood Behind
Erythropoietin has a tissue-protective activity entirely separate from its effect on red blood cells. ARA-290 is the fragment that isolates it — and unlike most research peptides, it has been through a randomised controlled trial in patients.
5-Amino-1MQ: The One in This Catalogue That Is Not a Peptide
Everything else here is amino acids. 5-Amino-1MQ is a small molecule that inhibits NNMT — an enzyme whose knockdown protected mice against diet-induced obesity in a 2014 Nature paper. Different chemistry, different handling, different research questions.
SNAP-8 (Acetyl Octapeptide-3): The Topical Peptide That Works on Signal, Not Structure
Most cosmetic peptides in research aim at collagen. SNAP-8 does something different — it targets the neurotransmitter release step at the neuromuscular junction. Here is the mechanism, how it relates to Argireline, and what to verify before buying.
PNC-27: A Strictly In Vitro Compound, and Why That Restriction Is the Interesting Part
PNC-27 incorporates an HDM-2-binding domain and is studied in cell-culture cancer models. It is the one compound in this catalogue where the in vitro restriction is not boilerplate — it is the actual research context. Here is the mechanism and the honest state of the evidence.

BPC-157 vs TB-500: Why the Most Common Comparison in Peptide Research Is the Wrong One
One was isolated from stomach acid. The other from a protein in nearly every cell you have. They are studied in the same models through mechanisms that do not overlap at all — which makes "which is better" the wrong question.
Semax vs Selank: Same Laboratory, Same Trick, Completely Different Ancestors
Both were built in the same Moscow institute using the identical three-residue stabilisation trick — which makes them look like siblings. One descends from a stress hormone, the other from an antibody fragment. Here is what that actually changes.
GHK-Cu vs GLOW: One Molecule You Can Check by Eye, One Formulation You Cannot
GHK-Cu is the only compound in the reference library whose condition you can partly assess by looking at it — it is blue, and the colour is data. A blend gives up that clarity in exchange for covering several pathways at once. That trade is the whole comparison.
CJC-1295 vs Tesamorelin: Two Engineering Answers to the Same Two-Minute Problem
Native GHRH is destroyed by an enzyme within minutes of reaching circulation. Tesamorelin caps the end of the molecule to block it. CJC-1295 rebuilds the sequence from the inside. Same problem, opposite solutions — and the difference shows up on the bench.
NAD+ vs MOTS-c: The Mitochondrion as Author, and as Engine
One of these is a message the mitochondrion writes and sends to the rest of the cell. The other is the currency it runs on. Both sit at the centre of longevity research — and neither should be handled the way you would handle a peptide.
