Regenpep: Advancing Science Through
Uncompromised Purity
We are more than a supplier; we are a strategic partner to the scientific community. Regenpep provides high-purity, laboratory-grade peptides verified by HPLC and Mass Spectrometry, ensuring that your research data is built on a foundation of absolute integrity.
Redefining Reliability in Peptide Synthesis
The field of biochemical research is exacting. Variables must be controlled, and the margin for error is non-existent. Yet, for too long, researchers have faced a marketplace flooded with inconsistent products, opaque sourcing, and questionable purity claims. Regenpep was established to solve this crisis of confidence.
Our mission is singular: to equip laboratories, universities, and independent researchers with reference materials that meet the highest standards of chemical fidelity. We understand that a single impure batch can compromise months of longitudinal studies. That is why we have engineered a supply chain that prioritizes traceability, transparency, and testing above all else.
By partnering directly with ISO 9001:2015 accredited manufacturing facilities, we eliminate the degradation risks associated with long storage times and multiple middlemen. When you order from Regenpep, you are receiving compounds that have been synthesized, lyophilized, and sealed with the express purpose of maintaining structural integrity until they reach your bench.

Why Purity Metrics Matter
Understanding the difference between 95% and 99% in a research setting.
High-Performance Liquid Chromatography (HPLC)
Purity is not an abstract concept; it is a measurable value. We utilize HPLC to separate, identify, and quantify each component in a mixture. In peptide synthesis, “impurities” often consist of deletion sequences (peptides missing one amino acid) or incomplete deprotection byproducts.
Regenpep standards require a minimum purity of ≥99% for our premium line. This minimizes the risk of experimental noise caused by truncated sequences interacting with cellular receptors in unforeseen ways. Lower purity peptides (95-98%) may contain Trifluoroacetic acid (TFA) salts or water content that skews mass weighting, leading to inaccurate dosing calculations in your experiments.
Mass Spectrometry (MS) Analysis
While HPLC determines purity, Mass Spectrometry confirms identity. It measures the mass-to-charge ratio of ions to verify the molecular weight of the peptide matches the theoretical weight of the amino acid sequence.
Every batch at Regenpep undergoes MS analysis to ensure the correct molecular structure. This is critical for preventing “sequence errors” where an amino acid might be swapped (e.g., Leucine vs. Isoleucine) which HPLC alone might struggle to differentiate. Our commitment to dual-verification (HPLC + MS) ensures you are working with the exact chemical structure your protocol demands.
The Art of Lyophilization
Peptides in solution are fragile and prone to hydrolysis or oxidation. To ensure longevity, our products are lyophilized (freeze-dried) into a stable powder cake. This process involves freezing the product and then reducing the surrounding pressure to allow the frozen water in the material to sublimate directly from the solid phase to the gas phase.
The result is a highly stable powder that can endure shipping at ambient temperatures while retaining its potency. This “powder cake” appearance is a hallmark of quality; a collapsed or melted cake can indicate improper processing or heat exposure, which is why our visual inspection protocols are as rigorous as our chemical ones.
Domestic Logistics & Speed
In biological research, timing is often a critical variable. Waiting weeks for international shipments is not an option for active laboratories. Regenpep operates a streamlined, USA-based fulfillment center.
By warehousing our verified inventory domestically, we ensure rapid turnaround times. Most orders are processed within 24 hours. Furthermore, domestic shipping removes the risks associated with customs holds or temperature fluctuations during trans-oceanic transit, ensuring your materials arrive in optimal condition.
Privacy & Data Security
We respect the nature of your work and your right to privacy. Whether you are an independent researcher or purchasing for an institution, your data is sacrosanct.
Our website employs advanced SSL (Secure Socket Layer) encryption for all connections. Our payment processing is tokenized and compliant with the highest security standards. We do not sell customer data, and our packaging is discreet to ensure professional delivery to your facility.
Frequently Asked Questions
Are your peptides suitable for human consumption?
No. All products sold by Regenpep are strictly for in-vitro laboratory research and development use only. They are not intended for human or animal consumption, therapeutic, or diagnostic use. Our products are sold to qualified researchers who understand the protocols for handling lyophilized proteins.
What is the difference between research grade and GMP grade?
Research Grade peptides are intended for laboratory experiments (cell culture, biochemical assays) and are typically >98% pure but not manufactured under full GMP (Good Manufacturing Practice) regulations required for human clinical trials. Regenpep supplies premium Research Grade materials suitable for high-sensitivity R&D applications.
How should I store my peptides upon arrival?
Upon receipt, lyophilized peptides should be stored in a freezer at -20°C (or colder) to maintain stability for months or years. Once reconstituted (mixed with bacteriostatic water or solvent), they typically must be kept refrigerated at 4°C and used within a shorter timeframe, depending on the specific peptide’s stability profile.
Do you provide Certificates of Analysis (COA)?
Yes. We believe in total transparency. Batch-specific Certificates of Analysis demonstrating HPLC purity and Mass Spectrometry identity are available. This allows you to verify that the reagent you are using matches the stringent requirements of your study.
