The short answer
How are SLU-PP-332 and retatrutide different?
SLU-PP-332 and retatrutide are both sold by us as freeze-dried research powders. They are not the same kind of compound, and they are not interchangeable on a lab bench.
Retatrutide is a synthetic single-chain peptide, an incretin analog. SLU-PP-332 is a small synthetic molecule, not a peptide. That gap in make-up is the main difference between the two.
Because they are built differently, each one has its own label, its own certificate and its own product page. Read those pages for specs rather than assuming one matches the other.

Other names
What else are they called?
SLU-PP-332 is also written SLU PP 332 or SLUPP332. You may see it listed as ERR agonist SLU-PP-332, which is how some suppliers name it. The hyphens and spaces vary, so match on the full name on the label.
Retatrutide is sometimes shortened to Reta, and some vendors print GLP-3 on the vial. We use Retatrutide on ours.
A search for one of these names can turn up the other. If a listing shows only a nickname and no full name, treat that as a gap in the paperwork.
Spelling matters most for SLU-PP-332, because the digits are easy to drop or swap. Check the full run of letters and numbers against the product page before you compare anything else.

Sizes
Which sizes come in the box?
SLU-PP-332 comes as a 10mg vial. You can take one vial, or a kit of the same vial. Retatrutide comes in three sizes: 10mg, 30mg and 60mg, each as a single vial or a kit.
A kit holds more vials of the same size from the same run. A lab running a longer series often takes a kit so each run starts with matched material.
The live sizes and stock for each compound are shown in the order box on its product page.

| Retatrutide | 10mg, 30mg, 60mg | Yes |
Paperwork
What should you check on the certificate?
Start with the lab name and the test date. Then look for the identity result and the purity number. Identity tells you the vial holds the compound on the label.
For a small molecule like SLU-PP-332 and a peptide like retatrutide, the identity test is different. A peptide report usually shows a mass. A small molecule report may show a mass or a structure scan. Neither is better. Each should fit the compound.
Our certificates are posted on the certificate page. Some chemistry fields for both compounds are still being confirmed, so we link to the product pages for specs instead of printing them here.
