Research Guides
These laboratory guides cover practical work with research peptides. Each one stays focused on the method and links to published literature summarized on our product pages.
How to Reconstitute Peptides
Step-by-step peptide reconstitution: choosing a diluent, calculating concentrations, aseptic technique, and the mistakes that degrade peptides in solution.
Peptide Storage & Handling
How to store lyophilized and reconstituted peptides: temperature windows, light and moisture control, transit stability, and shelf-life expectations.
How to Read a COA
What each line of a peptide COA means — HPLC purity, mass spec identity, endotoxin, heavy metals — and the red flags that separate real testing from marketing.
Bacteriostatic Water Explained
Bacteriostatic water vs sterile water for peptide research: how 0.9% benzyl alcohol works, when each diluent is appropriate, and safe handling practice.
BPC-157 Research Overview
What the published literature on BPC-157 actually covers: tendon and ligament models, gastrointestinal protection, angiogenesis — and the limits of the evidence.
TB-500 Research Overview
TB-500 in the published literature: actin sequestration, cell migration, dermal and corneal wound models, cardiac studies, and what remains preclinical.
BPC-157 vs TB-500
BPC-157 and TB-500 compared: origin, mechanism, study models and stability — why the research literature treats them as complementary rather than interchangeable.
Semaglutide Research Overview
Semaglutide as a research compound: GLP-1 receptor pharmacology, the published SUSTAIN and STEP trial programs, and current laboratory research directions.
Tirzepatide vs Retatrutide
Tirzepatide (GIP/GLP-1) and retatrutide (GIP/GLP-1/glucagon) compared: receptor pharmacology, published trial results, and how researchers choose between them.
Retatrutide Research Overview
Retatrutide's mechanism and evidence: GIP/GLP-1/glucagon triple agonism, the 2023 phase 2 results, liver-fat findings, and the open questions phase 3 must answer.
GH Secretagogues Compared
Compare sermorelin, CJC-1295 and ipamorelin by receptor, mechanism, half-life and use in growth-hormone secretagogue research.
GHK-Cu Research Overview
Research on GHK-Cu spans collagen synthesis, wound models, age-related decline, gene-expression profiling, and practical handling of the blue copper complex.
Reconstituted Peptide Stability
Stability windows for reconstituted peptides at refrigerator temperature: what drives degradation, how semaglutide-class compounds differ, and when to retire a vial.
Peptide Calculation Guide
Calculate peptide concentrations, per-draw quantities, serial dilutions and mass-to-molarity conversions for in-vitro laboratory work.
HPLC Purity Explained
Learn how HPLC purity is calculated, why identity needs mass spectrometry and how peptide impurities can affect laboratory assays.
