GLP3-RT Discontinued? A Lower-Cost Retatrutide (GLP-3 RT) Alternative to AlphaLabs
If you ordered GLP3-RT from GoAlphaLabs (AlphaLabs Peptides), you may have received an email titled "GLP3-RT DISCONTINUATION CONTINUES!" saying the final GLP3-RT inventory is selling alongside a 30% off sitewide sale. If you are now looking for where to buy GLP3-RT, or a retatrutide alternative to AlphaLabs, this page lays out the facts and our prices.
Snowman Research does not offer dosing information or usage guidance of any kind. Everything on this page is reference material about research products sold for laboratory research only.
What is GLP3-RT?
"GLP3-RT" and "GLP-3 RT" are common nicknames for retatrutide (LY3437943, CAS 2381089-83-2), a triple-agonist research peptide studied at the GLP-1, GIP and glucagon receptors. Vendors use different coded names for the same compound. Snowman Research lists it simply as Retatrutide, supplied as lyophilized powder for laboratory research only.
Is AlphaLabs discontinuing GLP3-RT?
AlphaLabs' customer email says its GLP3-RT is being discontinued and that the final inventory is on sale. We have not seen a public statement explaining why, so we won't guess. At the time of writing, GLP3-RT product pages were still live on their site at sale prices. If you rely on a steady retatrutide supply for ongoing research, now is a good time to line up a second source.

Why our prices are lower
We run a lean shop. We don't spend on influencer deals, paid ads or big promotions, so we don't have marketing costs to build into the price of each vial. That's the whole story: you pay for the research compound, not an ad budget.
