About Retatrutide(GLP-3)PremixedPen
The GLP-3 (RT) pre-mixed pen in Canada is supplied by Horizon Peptides in 16 mg and 40 mg research pens, available singly or in 3-pen and 5-pen packs. The pen supplies GLP-3 (RT) already in solution, so no preparation step is required before laboratory handling.
GLP-3 (RT) is a long synthetic sequence carrying several Aib substitutions, non-standard residues introduced to resist enzymatic cleavage. Its molecular formula is C162H261N43O51 with a molecular weight of 3493.83.
The pen differs from the vial in one respect: the material arrives already in solution at a set concentration. For comparative work across many samples, that removes preparation as a variable, which is the main reason a laboratory would choose this format over powder.
Two pen sizes are stocked so that a study can be matched to the quantity of material required.
Key research areas
- Multi-receptor metabolic signalling models
- Receptor-binding and selectivity assays
- Aib-substituted peptide stability research
- Pre-prepared solution consistency across sample sets
- Comparative studies against lyophilized presentations
Research areas describe how this material appears in published laboratory work. They are not claims about any effect in people or animals.
Other GLP-3 (RT) formats and related research peptides
The same compound is stocked as GLP-3 (RT) lyophilized vials in four sizes. Comparable metabolic receptor sequences include tirzepatide and semaglutide.

Research background
Retatrutide, first published under the code LY3437943, is a synthetic peptide that activates three hormone receptors at once: those for GIP (glucose-dependent insulinotropic polypeptide), GLP-1 (glucagon-like peptide-1) and glucagon.

Testing and documents
Batch documents are published on the Lab Results page as they become available, searchable by product or batch.
What a certificate of analysis shows
-
Identity
Mass spectrometry checks the measured molecular mass against the expected one: is this the right molecule.
-
Purity
HPLC separates a sample and reports the target as a share of everything detected.
-
Batch
A certificate describes one batch. The batch on the document should match the one you are asking about.
-
Date and analyst
The document should say who carried out the analysis and when.
Not every batch has a published document. Where one exists, it is listed; this page says nothing about results.
