Peptide Research

One page per compound. What it actually is, what the published work examined, what it did not, and the questions still open. Written to be read before you buy anything, not after.

GHK-CuCopper Peptide ComplexYour body already makes this one, and makes less of it as you get older. GHK-Cu is that same tripeptide bound to copper, and it is the reason copper peptides ended up in skincare at all.Read the researchBPC-157Body Protective CompoundYour stomach makes a protein known for protecting tissue. BPC-157 is the small piece of it researchers pulled out, and have been studying ever since.Read the researchTB-500Thymosin Beta-4Your cells are full of a protein that holds their internal scaffolding together. TB-500 is a synthetic copy of it, the full sequence, nothing trimmed.Read the researchMOTS-cMitochondrial Open Reading Frame PeptideAlmost every peptide in your body is written in the cell nucleus. This one is written inside the mitochondria, which is exactly what made it worth a second look.Read the researchCJC-1295 No DACGrowth Hormone-Releasing Hormone AnalogYour pituitary waits for a signal before it releases growth hormone. CJC-1295 No DAC is a synthetic version of that signal, rebuilt to survive a little longer.Read the researchGLOWResearch Peptide BlendThree peptides in one vial: GHK-Cu, BPC-157 and TB-500. Each is sold on its own here, and each has its own research behind it.Read the researchTirzepatideDual GIP and Incretin Receptor AgonistMost peptides in this space work one receptor. This one works two at once, and that single design decision is what made the whole field pay attention.Read the researchRetatrutideTriple Receptor AgonistTirzepatide pulled two levers at once and reset the field. Retatrutide pulls three, and the research program around it is now one of the largest running.Read the research
Long readTirzepatide vs RetatrutideTwo receptors versus three. What the third one actually does, where each compound is in its research program, and the honest answer to which is further along. Both are on this site, so we say what separates them rather than picking one.Read the comparison
