Research Peptides FAQ
Research peptides explained: what they are and why they’re used
Research peptides are short chains of amino acids used in laboratories to study biological processes such as repair, regeneration, and cellular signalling. They are supplied as highly purified powders for laboratory research only. While not licensed medicines or supplements, they are valuable tools for generating reliable scientific data. Bluewell supplies batch-specific COAs so researchers know exactly what they are working with.
What does “COA-verified peptides” mean?
A Certificate of Analysis confirms that a batch has been independently tested for identity and purity using techniques such as HPLC and mass spectrometry. Each Bluewell batch ships with its own COA for transparency.
Why 99%+ purity matters for peptide research
High purity reduces interference from byproducts and supports reproducibility. Bluewell Peptides provides HPLC-verified 99.1% purity so researchers can work with confidence.
How to confirm peptides are genuine
Look for batch-matched COAs, technical identifiers, and clear specifications. Bluewell publishes documentation for every product to ensure traceability and trust.
Why products note “for research use”
To keep expectations clear and compliant: our peptides are produced and documented for laboratory research. They are not marketed as medicines or dietary products.
Are peptides safe for laboratory research?
When sourced as research-grade material and used according to protocol at appropriate concentrations, peptides are generally well tolerated in model systems. Safety depends on the compound, dose, solvent, and methodology. Not for human consumption.
Why are peptides supplied as a lyophilised powder?
Lyophilisation (freeze-drying) maximises stability and shelf life, reducing hydrolysis and microbial growth. Researchers reconstitute immediately before use to control concentration and maintain integrity.
What are the best peptides for research in 2025?
Popular research peptides include BPC-157, TB-500, GHK-Cu, CJC-1295, Retatrutide, and many more. These compounds are being studied for their potential roles in regeneration, recovery, metabolism, neuroprotection, and cellular repair. There’s a peptide for almost everything in modern research — you can explore our full range here: https://bluewellpeptides.com/product-category/all-peptides/.
How can I verify peptide quality or purity?
We have a dedicated Certificate of Analysis (COA) page where every batch is listed and verified twice — first during manufacturing and again by Axonis Analytics, an independent third-party testing lab. Each COA confirms identity and purity via HPLC and mass spectrometry. View COAs at https://bluewellpeptides.com/certificate-of-analysis-coa/. Get in touch if you’d like more details about a specific batch or test report.
Retatrutide 10 mg – Metabolic and Weight Management Research
Retatrutide is an investigational multi-receptor peptide agonist that has gained attention in metabolic research for its potential to regulate glucose metabolism, energy expenditure, and appetite control. It targets GLP-1, GIP, and glucagon receptors, making it one of the most advanced peptides studied for comprehensive metabolic optimization. Researchers explore Retatrutide in models related to insulin sensitivity, fat oxidation, and weight regulation, positioning it as a next-generation candidate in obesity and diabetes research.
Melanotan II (MT2) 10 mg – Pigmentation and Photoprotection Research
Melanotan II, or MT2, is a synthetic analog of the natural melanocortin peptide α-MSH. It is widely studied in pigmentation research for its ability to trigger melanogenesis—the body’s natural tanning process—by stimulating melanin production in skin cells. MT2 is also researched for its potential roles in photoprotection, appetite regulation, and libido modulation.
BPC-157 5 mg – Healing, Recovery, and Regenerative Research
BPC-157 is one of the most studied repair peptides for tissue healing and regeneration, frequently used in models for muscle recovery, joint healing, and anti-inflammatory response.
TB-500 5 mg – Wound Healing and Tissue Regeneration
TB-500, a synthetic fragment of Thymosin Beta-4, is studied for angiogenesis, actin upregulation, and inflammation control. Often paired with BPC-157 for synergistic effects in regeneration.
GHK-Cu 50 mg – Collagen, Skin, and Hair Research
GHK-Cu supports collagen synthesis, wound repair, elasticity, and antioxidant protection; also explored for hair follicle health.
Selank 5 mg – Nootropic and Stress Modulation Research
Selank is researched for nootropic and anxiolytic potential via GABA/serotonin modulation; studied for cognitive performance and stress resilience.
Semax 5 mg – Neuroprotection and Cognitive Function
Semax may promote neurotrophic factor expression (e.g., BDNF) and is studied for memory, focus, and neuroprotection.
CJC-1295 (No DAC) 5 mg – GHRH Analog
Short-acting GHRH analog used to explore pulsatile GH release, impacts on IGF-1, fat metabolism, and recovery.
CJC-1295 (With DAC) 5 mg – Extended Half-Life GHRH Analog
Albumin-binding extends half-life for more sustained GH profiles, studied for body composition and cellular repair models.
Ipamorelin 5 mg – Ghrelin Receptor Agonist Research
Selective GH secretagogue often paired with CJC-1295; studied for recovery and anti-aging applications.
Sermorelin 5 mg – GRF 1-29
Benchmarked in GH research for stimulating the pituitary’s natural GH production; explored in metabolic and recovery studies.
IGF-1 LR3 1 mg – Growth, Muscle, and Cellular Repair

Tesamorelin 5 mg – GHRH Analog
Studied for effects on body composition, lipid metabolism, and visceral fat.
Glutathione 15 mg – Cellular Antioxidant and Detoxification Research
Master antioxidant studied for redox balance, immune function, and detoxification.
Bacteriostatic Water 10 mL – Sterile Solvent for Research Use
0.9% benzyl alcohol diluent used for reconstituting lyophilised peptides with multi-use vial stability.
Why reconstitution matters
Peptide powders are lyophilised to maximise stability and shelf life. Correct reconstitution preserves activity and helps prevent degradation, aggregation, or contamination.
How to reconstitute peptides (quick start)
Let both the vial and bacteriostatic water reach room temperature (15–20 minutes). Disinfect stoppers with alcohol. Add 1–3 mL bacteriostatic water slowly down the vial wall; swirl gently until dissolved. Store at 2–8 °C. For exact volumes, use the Bluewell Peptide Calculator.
Best solvents for peptide research
Bacteriostatic water is standard. Sterile Water for Injection for single-use. Dilute acetic acid can aid difficult dissolutions.
Storing unmixed peptides (powder form)
Freezer (-20 °C): long-term (up to 4 years).
Fridge (2–8 °C): 12–24 months sealed.
Room temperature: only a few days.
Keep sealed: protect from light, moisture, and temperature swings.
Storing reconstituted peptides
Refrigerate at 2–8 °C. For longer horizons, aliquot and freeze to avoid repeated freeze–thaw; use a suitable cryoprotectant if storing frozen for extended periods.
How long do reconstituted peptides last?
Typical refrigerated stability is 3–6 weeks (practical sweet spot ~4 weeks). Frozen aliquots can last longer depending on protocol.
Common mistakes to avoid
Using tap or boiled water.
Vigorous shaking/vortexing.
Not letting vials reach room temp before opening.
Reusing needles/excess stopper punctures.
Multiple freeze–thaw cycles on the same vial.
