Frequently Asked Questions
Quick answers to common inquiries regarding product handling, analytical testing, documentation, and shipping procedures.
What are research peptides and who are they intended for?
Research peptides are synthetic amino acid compounds that scientists and researchers use to investigate specific biological pathways, receptor pharmacology, and physiological mechanisms in controlled laboratory settings. They are intended exclusively for use by qualified researchers, scientists, and laboratory professionals conducting in vitro assays and preclinical studies. Furthermore, all peptides available in this catalog are supplied strictly for research purposes and are not intended for human or veterinary administration. Researchers working in endocrinology, metabolic biology, neuroscience, immunology, regenerative medicine, and aging biology are the primary users of our research compound catalog.
What purity standards do your research peptides meet?
All research peptides in our catalog meet a minimum purity standard of ≥98% as verified by high-performance liquid chromatography (HPLC). Furthermore, each compound undergoes rigorous quality control before shipping to ensure consistent purity, accurate labeling, and lyophilized powder integrity. Researchers can therefore rely on our compounds for precise dose-response studies, receptor pharmacology assays, and preclinical research protocols where compound purity directly affects data reliability and reproducibility. Additionally, we supply compounds in sealed, labeled vials to maintain integrity from production to point of reconstitution.
How should I reconstitute and store lyophilized research peptides?
The correct reconstitution solvent depends on the specific peptide. Most compounds in our catalog — including GLP-1 agonists, GHRH analogues, GHRPs, BPC-157, TB-500, and cognitive research peptides — reconstitute cleanly with sterile bacteriostatic water. However, certain peptides such as IGF-1 LR3, Melanotan I, and Melanotan II require initial solubilization with dilute acetic acid water before dilution to working concentration. Furthermore, we recommend adding solvent slowly along the inner vial wall and swirling gently — never shaking or vortexing — to preserve peptide integrity. Store all lyophilized vials at −20°C before reconstitution. Once reconstituted, maintain solutions at 4°C and use within 28–30 days. We supply both bacteriostatic water and acetic acid water as accessories to support your reconstitution workflow.
What is the difference between CJC-1295 with DAC and CJC-1295 without DAC?
Both CJC-1295 variants target the GHRH receptor on pituitary somatotroph cells and stimulate GH secretion. However, they differ fundamentally in their pharmacokinetic profiles and therefore serve different research purposes. CJC-1295 without DAC produces defined, short-to-intermediate duration GH pulses — making it the preferred tool compound for researchers studying GH pulse amplitude, pituitary responsiveness, and time-controlled GH stimulation protocols. CJC-1295 with DAC incorporates Drug Affinity Complex technology that enables covalent albumin binding, dramatically extending its active half-life from hours to days. Consequently, researchers use the DAC version in protocols requiring sustained, continuous GH elevation over extended experimental timeframes. Both variants are available separately to give researchers complete flexibility across the full range of GH axis research designs.
Can I use multiple peptides together in the same research protocol?
Yes — many researchers design multi-compound experimental protocols to study synergistic or complementary pathway interactions. For example, pairing a GHRH analogue such as CJC-1295 with a GHRP such as Ipamorelin allows researchers to study synergistic GH release through simultaneous GHRHR and GHSR-1a co-activation. Similarly, combining Cagrilintide with Semaglutide enables investigation of dual amylin and GLP-1 receptor pathway activation. Furthermore, we offer several pre-formulated combination products — including the CJC-1295 + Ipamorelin Blend, BPC + TB Blend, and Cagrilintide + Semaglutide — to simplify multi-compound research protocols and improve dosing consistency. Researchers should always design multi-compound protocols within their institutional research framework and validated experimental SOPs.
Are your research peptides available for shipping across Canada?
Yes — we ship research-grade peptides and lab supplies across Canada. All orders are carefully packaged to maintain lyophilized compound integrity during transit. Furthermore, our pricing is displayed in both USD and CAD to provide full transparency for researchers ordering within Canada.
