Why the names are coded at all
Amino Club
GLP-3 (RT)
Amino Club's product pages do not say retatrutide, tirzepatide or semaglutide. They say GLP-3 (RT), GLP-2 (TR) and GLP-1 (SM).
Research-chemical vendors commonly do this. Printing a brand-name drug's generic name next to a buy button invites trademark and regulatory attention, so the compound gets a house code instead.
The practical effect on a buyer is simple and not good: you cannot tell what you are ordering unless you already know the shorthand. That is why people search whether Amino Club sells real reta. They are trying to confirm the thing they are already looking at.

Amino Club code names and what they refer to
GLP-3 (RT): retatrutide
Retatrutide acts on three receptors at once: GLP-1, GIP and glucagon. That third one is what separates it from tirzepatide, and it is why the published trial results drew so much attention.
It is investigational. Eli Lilly has run it through mid-stage trials with striking weight-loss numbers, but it has not completed the full approval process anywhere in the world. No regulator has cleared it for use in people.
So a research vial of GLP-3 is not an early version of a prescription. It is a compound still being studied, sold outside any medical supervision.
GLP-2 (TR) and GLP-1 (SM): approved drugs, unapproved supply
Tirzepatide and semaglutide are different from retatrutide in one important way: both are approved medicines, sold as Mounjaro, Zepbound, Ozempic and Wegovy.
That does not make a research vial equivalent to a prescription. An approved product carries a known manufacturer, a regulated supply chain, a pharmacist and a dose titrated by a clinician. A research vial carries a certificate.
The gap between those two things is the entire reason this category exists, and the code name on the label does nothing to close it.
The rest of the catalog is named plainly
Outside the GLP range, Amino Club mostly uses real names: BPC-157, TB-500, GHK-Cu, MOTS-C, KPV, Ipamorelin, Epithalon, Selank, Semax.
A few house names still appear. GLOW is a BPC-157, TB-500 and GHK-Cu blend. KLOW adds KPV to that. The Wolverine stack is BPC-157 with TB-500. Our dosing hub covers where the figures for those blends come from.
Research Mist is the nasal-spray line: the same compounds supplied in solution rather than as powder you reconstitute.
What this means before you order
Decode the name first, then look up the compound rather than the code. The evidence base for retatrutide is not the same as for semaglutide, and neither resembles BPC-157.
Check the certificate for your specific batch. The code name tells you nothing about what a lab measured.
All of it is sold for laboratory research. That framing is easier to lose sight of when the label reads GLP-3 instead of the name of a drug you have seen advertised.
