Research Peptide FAQ

Same-day dispatch on orders before the daily cutoff (HST) on business days. Most domestic orders arrive within 2 to 4 business days via USPS Priority Mail.

Yes. Orders of $400 or more ship free via USPS Priority Mail and also include free bacteriostatic water, one 3mL vial per peptide vial in your cart. Under $400, USPS Priority is a flat $19.99. If you need it faster, USPS Priority Express is $29.99 for 1 to 2 business days and is never discounted.

All orders ship in discreet, unmarked packaging with tracking. Lyophilized peptides are shelf-stable and ship safely with standard packaging. An optional cold chain add-on with insulated containers and gel ice packs is available at checkout for researchers who want extra temperature assurance.

Yes. We ship within the United States via USPS Priority Mail and internationally via USPS Priority International and Priority Express International. Shipping options and rates are shown at checkout based on your destination.

You'll receive a tracking number via email as soon as your order ships. You can also track orders directly from your account dashboard at any time.

All peptides are guaranteed ≥99% purity. Every batch is independently verified by third-party HPLC analysis and mass spectrometry before it ships. We never self-certify.

COAs are available on every product page, view online or download the PDF. Each COA includes batch number, purity percentage, and full testing methodology.

Lyophilized (powder) peptides should be stored at -20°C for long-term stability. Once reconstituted, refrigerate at 2-8°C and use within 14-28 days depending on the compound. Never refreeze a reconstituted peptide.

Most likely, yes. Our compounds ship as lyophilized (freeze-dried) powder, and most peptides require bacteriostatic water to reconstitute before use. If you are not sure, one 10mL vial covers most orders. Orders of $400 or more include free bacteriostatic water, one 3mL vial per peptide vial in your cart.

Bacteriostatic water (BAC water) is sterile water containing 0.9% benzyl alcohol. It's used to reconstitute lyophilized peptides. The preservative prevents bacterial growth, allowing multi-use from a single vial for up to 28 days.

Use our free Peptide Calculator, enter your vial size and target dose, and it outputs the exact syringe mark, total concentration, and doses per vial.

Yes, every single batch. Independent, accredited laboratories perform HPLC purity testing, mass spectrometry for identity confirmation, and endotoxin analysis. Full results are published on each product COA.

Research peptides are short chains of amino acids synthesized for scientific investigation. Compounds like BPC-157, TB-500, and Semax are studied for their biological activity in controlled laboratory settings. They are not approved for human use.

Lyophilized means freeze-dried. Peptides are frozen then placed in a vacuum chamber where water is removed through sublimation, converting ice directly to vapor without a liquid phase. This preserves potency and extends shelf life to 24 or more months at -20°C.

Draw bacteriostatic water into a sterile syringe. Angle it against the inside wall of the vial and add it slowly, never spray directly onto the powder. Gently swirl until fully dissolved. Never shake. Use our Peptide Calculator to determine the exact BAC water volume for your target dose.

HPLC (High-Performance Liquid Chromatography) is the gold-standard method for measuring peptide purity. A sample is separated by molecular properties under high pressure, producing a chromatogram that quantifies purity as a percentage. Blackwell BioLabs requires ≥99% HPLC purity on every batch.

BPC-157 is a synthetic 15-amino-acid peptide derived from a gastric protein, studied in animal models for tissue and gastrointestinal repair research. TB-500 is a synthetic fragment of Thymosin Beta-4, researched for its role in actin regulation and cellular migration. They are structurally distinct compounds with different mechanisms of action, often studied together.

Mass spectrometry (MS) confirms a compound's molecular identity by measuring its mass-to-charge ratio. While HPLC tests purity, MS verifies the compound is exactly what it claims to be. Blackwell BioLabs uses both HPLC and mass spectrometry on every batch, dual verification of purity and identity.

No. All Blackwell BioLabs products are sold strictly for in-vitro laboratory research purposes only. They are not intended for human or veterinary use, consumption, or administration. All customers are responsible for compliance with applicable laws in their jurisdiction.

We offer a 30-day money-back guarantee on all products. If you're not satisfied for any reason, contact us for a full refund, no questions asked.

Contact us immediately with photos of the damage. We'll ship a replacement at no cost, or issue a full refund, your choice.

Orders can be cancelled within 1 hour of placement. After that, orders enter processing and cannot be cancelled, but you can return the product under our 30-day money-back guarantee.
