Claim-free literature overviews, analytical methodology, and batch announcements.
Semax: A Research Primer
What Semax actually is: a synthetic heptapeptide (MEHFPGP) built as an ACTH(4-10) analogue, its CAS and formula data, the research fields that reference it, and how it is handled and tested as a reagent.
Tirzepatide: A Research Primer
What tirzepatide is at the identity level: a synthetic 39-amino-acid dual GIP/GLP-1 receptor agonist, its CAS number and formula, the research field that references it, and how it is handled and tested as a laboratory reagent.
Semaglutide: A Research Primer
Semaglutide explained: a long-acting GLP-1(7-37) receptor agonist analog, its CAS number and molecular formula, the backbone sequence and side-chain chemistry, the research field it appears in, and how each lot is handled and tested.
PT-141: A Research Primer
What PT-141 (Bremelanotide) actually is: a synthetic cyclic melanocortin peptide, its CAS number and formula, the sequence on the label, the research field that references it, and how each lot is tested.
Tesamorelin: A Research Primer
Tesamorelin explained: the identity of this stabilized GHRH(1-44) analog, its CAS and molecular-formula data, the research field that references it, and how it is supplied and tested as a reagent.
CJC-1295 (no DAC): A Research Primer
What CJC-1295 (no DAC) is: a synthetic modified GRF(1-29) analog, also called mod GRF 1-29, with its CAS number and formula, the research field that references it, and how each lot is handled and tested as a reagent.
Selank: A Research Primer
What Selank is: the synthetic tuftsin analog's identity, its CAS and formula data, the neuropeptide and behavioural research areas that reference it, and how it is supplied and tested as a reagent.
Semax vs Selank: A Research Comparison
Semax and Selank compared by identity, not effect: an ACTH-related heptapeptide versus a tuftsin analog, their sequences and CAS numbers, and how each lot is supplied and tested.
BPC-157 vs TB-500: How They Differ
BPC-157 and TB-500 side by side on identity alone: different parent molecules, a 15-residue chain versus a 43-residue N-acetylated one, different CAS numbers, and the separate research fields each appears in.
Ipamorelin: A Research Primer
What Ipamorelin actually is: a synthetic pentapeptide growth hormone secretagogue and ghrelin-receptor ligand, its chemistry and CAS number, the research field it turns up in, and how each lot is handled and tested.
TB-500: A Research Primer
What TB-500 actually is: a synthetic 43-amino-acid peptide (CAS 77591-33-4), an N-acetylated fragment related to Thymosin Beta-4, the research fields it appears in, and how each lot is tested.
Buying Research Peptides in Vancouver
Why buying research peptides in Vancouver means no customs and same-day BC dispatch, why the per-lot certificate still matters more than the postcode, and what BC researchers should check before ordering.
BPC-157: A Research Primer
What BPC-157 actually is: a synthetic 15-amino-acid partial sequence (PL 14736), its chemistry and CAS number, and how each lot is tested.
GHK-Cu: A Research Primer
GHK-Cu explained: the copper-binding tripeptide's identity, chemistry and CAS data, the research areas it appears in, and how it is supplied and tested.
What HPLC Purity Percentage Actually Tells You
HPLC purity measures one narrow thing: the target peak's share of total detected area. Here is what that number hides, and why baseline, wavelength, and identity all matter.
Third-Party vs In-House Peptide Testing: Why It Matters
Why an independent lab number beats a supplier grading its own product, what third-party really means, and how to tell which test a COA is actually showing you.
Storing Lyophilized Research Peptides: A Handling Reference
Why research peptides ship freeze-dried with mannitol, and how to store the reagent at -20C, in the dark and sealed, with the chemistry behind each rule.
Red Flags When Buying Research Peptides
The warning signs of a bad research-peptide supplier: no per-lot COA, purity without identity, generic 99% badges, and no one you can actually reach.
Buying Research Peptides in Canada: What to Actually Check
A practical checklist for sourcing research peptides in Canada: per-lot certificates, domestic vs offshore shipping, payment norms, and the research-use-only line.
How to Read a Peptide Certificate of Analysis (Using Two of Ours)
A plain-language walkthrough of HPLC purity, mass-spec identity, and potency on a real peptide COA, worked through our BPC-157 and Retatrutide lab reports.
