Catalog differences
Research peptide comparisons
These notes keep catalogue records apart when two names are easy to collapse on a receiving log. Each page is catalogue differences only: sequence or length, receptor or target class named in the cited papers, fill size, and whether a Certificate of Analysis row is published. They are not a protocol. None of them ranks a vial for personal use. BlueNex Labs materials are research use only.
A missing certificate row means that lot was not published. It does not mean a neighbouring PDF applies. Semaglutide and SS-31 50 mg are examples of live URLs without a row. A blend file does not cover a different SKU. Open the certificates library for the rows that do exist. Payment is Interac e-Transfer. Parcels move on Canada Post Xpresspost inside Canada. Weekday cutoff and tracking expectations are on the provincial fulfilment FAQ.
Read the list as an index. Open the comparison, then open each shop URL named under it, then the certificate row when one is published. Sequence length and receptor class stay on the comparison. Price and stock stay on the shop URL. A Janoshik task identifier stays on the library row. Research-use-only labelling on any of those pages is not a Health Canada authorization and it does not create a Drug Identification Number.
Catalogue differences only. These notes compare sequences, receptor classes, fill sizes, and Certificate of Analysis rows. They are not a protocol, and they do not rank materials for personal use. Research use only.
Published rows are in the certificates library. Weekday cutoff and tracking are on the provincial fulfilment FAQ. Checkout is Interac e-Transfer and Canada Post Xpresspost. Class notes are on the mechanism hub. Short definitions are in the RUO glossary. These side-by-side notes follow the documentation standards. Questions about the scientific lead go to Alice Kay, Ph.D.
Melanotan I vs Melanotan II: Research Comparison
Melanotan I is the linear 13-residue analogue [Nle4, D-Phe7]-alpha-MSH. Melanotan II is a cyclic lactam heptapeptide. The shared nickname is why a receiving log collapses them. The note records chain versus ring, catalog size, and which certificate row exists. PT-141 and KPV sit on the same category route and are not either sequence.
CJC-1295 / Ipamorelin vs Ipamorelin: Research Comparison
One URL is ipamorelin alone, a five-residue ligand discussed at GHSR-1a. The other is a convenience fill that also contains CJC-1295 without the albumin-binding group, discussed as a GHRH-receptor analogue. The paired vial is not a larger ipamorelin lot. Each fill has a separate certificate row when one is published.
Sermorelin vs Tesamorelin: Research Comparison
Sermorelin and tesamorelin are both discussed as GHRH-receptor analogues, and they are not the same sequence or the same catalog URL. Each name has its own 10 mg listing. A mass match for one vial does not document the other. The note records which certificate rows were present on the library review.
Semaglutide vs Tirzepatide vs Retatrutide: Research Comparison
Semaglutide, tirzepatide, and retatrutide are separate incretin-class research fills. Papers assign them different receptor sets. Those sentences describe published literature. They are not assay results for a BlueNex Labs vial, and they are not a use instruction. Cagrilintide is an amylin analogue on the same category route and is not a fourth column in the table. Match each milligram size to its own lot file.
BPC-157 vs TB-500: Research Comparison
BPC-157 is a 15-residue gastric fragment. TB-500 is a thymosin beta-4 fragment. The catalog also sells two dual fills, 5 mg/5 mg and 10 mg/10 mg. A certificate for one container does not document the other three. TB-500 10 mg has its own purity row. The 5 mg/5 mg file is not a substitute.
Thymosin Alpha-1 vs TB-500: Research Comparison
Thymosin alpha-1 is a 28-residue thymic sequence. TB-500 is a short thymosin beta-4 fragment. Shared thymosin wording does not make the masses interchangeable. Each name has its own shop URL and its own documentation status. A report for one does not file the other.
MOTS-c vs SS-31: Research Comparison
MOTS-c is a 16-residue mitochondrial open-reading-frame peptide. SS-31 is a synthetic tetrapeptide discussed with cardiolipin in the inner mitochondrial membrane. Length alone separates them. The catalog lists more than one milligram size for each name. A certificate for one size does not document the other size, and the SS-31 10 mg file does not document MOTS-c.
GHK-Cu vs GLOW and KLOW: Research Comparison
GHK-Cu is the copper tripeptide on its own 50 mg URL. GLOW 70 mg and KLOW 80 mg are multi-peptide fills that include that complex plus other sequences. A GHK-Cu certificate does not document either blend, and a blend file does not document the single-complex vial. Component names on a label are not lot identity.
Semax vs Selank: Research Comparison
Semax is the ACTH-fragment heptapeptide Met-Glu-His-Phe-Pro-Gly-Pro. Selank is the tuftsin-derived heptapeptide Thr-Lys-Pro-Arg-Pro-Gly-Pro. Both listings are 10 mg, and both can wear a blue cap. The shared tail and the shared fill are why a receiving log collapses them. The note records the two sequences and which certificate row includes an endotoxin link.
GLOW vs KLOW: Research Comparison
GLOW 70 mg names GHK-Cu, TB-500, and BPC-157 and does not print a per-peptide split. KLOW 80 mg prints GHK-Cu 50 mg, BPC-157 10 mg, TB-500 10 mg, and KPV 10 mg. The copper-complex comparison is a different page. This note is blend versus blend: the component list, whether a split is printed, and the separate certificate rows.
Cagrilintide vs Semaglutide: Research Comparison
Cagrilintide is a lipidated amylin analogue on a 5 mg URL. Semaglutide is a GLP-1 analogue listed as 10 mg and 20 mg. A lipid mark in both papers does not make the classes the same. The three-way incretin comparison stays a different page. This note records the class split and which name had a certificate row on the library review.
PT-141 vs Melanotan II: Research Comparison
PT-141 and Melanotan II share a cyclic lactam scaffold. Melanotan II is the C-terminal amide. PT-141 is the C-terminal acid. The linear Melanotan I comparison is a different page. This note records the terminus, the 10 mg listings, and which name has a certificate row.
