High-Performance Liquid Chromatography (HPLC)
Every synthesized compound is screened using reversed-phase HPLC to quantify chemical purity levels. Loti Labs enforces a minimum threshold of ≥99.0% purity across our entire catalog. Chromatographic peak profiles are recorded and made fully accessible to verify the total absence of residual reagents, unwanted peptide side-products, or chemical degradants.
Mass Spectrometry (MS) & Molecular Weight Verification
To confirm molecular structure without ambiguity, each batch undergoes electrospray ionization mass spectrometry (ESI-MS) or Matrix-Assisted Laser Desorption/Ionization (MALDI-TOF). Spectra verify the observed monoisotopic molecular weight against calculated theoretical values, ensuring zero sequence errors or amino acid substitutions.
Public Certificate of Analysis (COA) Transparency
Every order shipped by Loti Labs corresponds directly to a verifiable, lot-specific Certificate of Analysis. Researchers can access complete batch chromatograms, mass spectra data, and laboratory technician sign-offs directly on lotilabsusa.com prior to conducting bench trials.
Regulatory Compliance & Cold-Chain Storage Specifications
Loti Labs operates in full adherence to domestic chemical distribution standards and scientific compliance frameworks. Our manufacturing, handling, and logistics infrastructure are engineered to preserve peptide bioactivity from synthesis to delivery.
Laboratory Storage & Lyophilization Handling
Lyophilized Powder Formulations: Synthesized peptides are freeze-dried into stable, amorphous solid cakes under sterile conditions to preserve tertiary structure and prevent degradation during transit.
Temperature Protocols: Finished products are stored in climate-controlled facilities kept strictly at -20°C to -80°C to preserve peptide bonds prior to fulfillment.
Desiccation & Nitrogen Purging: Vials are vacuum-sealed under an inert nitrogen blanket with low-moisture stoppers to prevent atmospheric hydration and hydrolysis during storage.

1. How does Loti Labs verify the purity and identity of its research peptides?
At Loti Labs, every single production batch undergoes double-blind testing at independent, ISO 17025-accredited analytical testing laboratories in the United States. We utilize High-Performance Liquid Chromatography (HPLC) to verify that chemical purity meets or exceeds our strict ≥99.0% threshold, ensuring the complete absence of residual reagents, trifluoroacetic acid (TFA) salts, or truncated side-products. Additionally, Electrospray Ionization Mass Spectrometry (ESI-MS) or MALDI-TOF analysis is conducted on every lot to verify monoisotopic molecular weight and exact sequence fidelity.
2. How can I view or verify the Certificate of Analysis (COA) for my order?
We maintain complete public transparency for every compound in our catalog. You can view or download the lot-specific Certificate of Analysis directly on the product page at lotilabsusa.com before making a purchase. Alternatively, you can use our batch lookup feature by entering the lot number printed on your product vial or package. Each COA displays raw HPLC chromatograms, mass spectra peaks, testing dates, and sign-offs from independent laboratory technicians.
3. Are products from Loti Labs intended for human or clinical use?
No. All products offered by Loti Labs—including lyophilized peptide vials, synthetic liquids, and biochemical reagents—are strictly sold for in vitro laboratory experimentation, analytical testing, and scientific research purposes only. They are not intended for human or animal consumption, clinical trials, therapeutic administration, or diagnostic procedures. Loti Labs is not a compounding pharmacy or a 503B outsourcing facility, and any misuse of our products violates our Terms of Service.
4. Where are Loti Labs products manufactured, stored, and fulfilled?
Our entire operation—from chemical synthesis and quality control to cold-chain storage and package dispatch—is housed 100% within the United States. By maintaining all operations domestically, Loti Labs eliminates international shipping delays, customs seizures, cross-border tariff complications, and unverified overseas supply chain risks. All inventory is stored in climate-controlled conditions (-20°C to -80°C) to prevent chemical degradation prior to fulfillment.
5. What are the recommended storage protocols for lyophilized peptides?
Upon receipt at your facility, unopened lyophilized (freeze-dried) peptide vials should be kept in a dry, dark environment at -20°C (-4°F) for optimal long-term stability (up to 24 months). If used short-term, storage at 4°C (39°F) is acceptable for up to 90 days. Avoid exposing vials to direct light, excessive moisture, or frequent freeze-thaw cycles. Once reconstituted with a sterile laboratory solvent (such as Bacteriostatic Water or Sterile Water for Injection), keep the solution refrigerated at 2°C–8°C and use within the recommended timeframe specified in your laboratory protocol.
6. What is your daily order processing cutoff and shipping timeframe?
Orders submitted and confirmed before 2:00 PM EST (Monday through Friday) qualify for same-day dispatch from our domestic fulfillment center. Orders placed after the cutoff time or over the weekend are dispatched on the following business day.

10. Why is my peptide cake appearing smaller or loose inside the vial?
Lyophilized peptide cakes can vary in physical appearance depending on the specific peptide sequence, mass, and freeze-drying conditions. A cake may appear as a solid plug, a fluffy powder, or slightly fragmented/loose at the bottom of the vial. This variation in physical form is completely normal and does not impact the quantity, purity, or chemical integrity of the compound. The precise mass is verified through analytical balances and HPLC testing prior to vial sealing.
