Semaglutide works on one receptor. Retatrutide works on three. That is the entire technical difference behind “reta vs sema” — but the two also sit in completely different legal categories, and mixing that up is the most common confusion in this space. Findings Semaglutide works on one receptor; retatrutide works on three. Semaglutide is an…

Retatrutide and tirzepatide are the two most requested research peptides in Canada right now, and the difference between them is one receptor. Tirzepatide is a dual agonist — GIP and GLP-1. Retatrutide, commonly shortened to “reta”, engages those same two receptors plus a third: the glucagon receptor. Everything else people debate about the pair follows…

The difference between GLOW and KLOW is exactly one peptide. Both blends are built on the same three-part core — GHK-Cu, BPC-157 and TB-500. KLOW adds a fourth, KPV. Choosing between them is really one question: does that fourth peptide belong in your research or not? Findings GLOW and KLOW differ by exactly one peptide….

Tesamorelin is a modified version of a hormone your body already makes. The natural molecule, growth hormone releasing hormone, is broken down in circulation within minutes. Tesamorelin is that same sequence with one structural change designed to slow the breakdown down — and that change is essentially the whole point of the compound. Findings Tesamorelin…

NAD+ is not a peptide. It sits in peptide catalogues, gets ordered alongside peptides, and is discussed in the same research conversations — but structurally it belongs to a different class of molecule entirely. That is worth understanding before you order it, because it changes what the purity figure on the COA is actually measuring….

Bacteriostatic water is sterile water with one addition: roughly 0.9% benzyl alcohol. That single ingredient is the entire difference between it and ordinary sterile water, and it is the reason it is the standard diluent in peptide laboratories rather than a nice-to-have. Findings Bacteriostatic water is sterile water plus about 0.9% benzyl alcohol, which stops…

GLP-1 is a real hormone. GLP-2 is a real hormone. “GLP-3” is not. It is a label that circulates in the research-peptide market, and it usually refers to retatrutide — a compound that is not a GLP-3 anything, because no such hormone exists. If you are searching these terms, here is what each one actually…

CJC-1295 and Ipamorelin act on growth hormone signalling by different routes. What the no-DAC form is, why the distinction matters, and how to verify it. Research use only.

MOTS-c is a mitochondrial-derived peptide studied for cellular energy and metabolic signalling. What it is, how it is supplied, and how to verify purity. Research use only.
