Each peptide batch includes its own Certificate of Analysis conducted at independent external facilities. All chemical analysis is performed using HPLC with UV detection coupled to mass spectrometry.

We are the only supplier in Brazil of research peptides that offers independent third‑party testing by certified laboratories. Our testing protocols verify molecular identity, CAS number confirmation, purity levels (98%+ or 99%+), and appearance specifications.

All COAs are available prior to purchase so you can verify quality standards for your research applications.

Each COA displays the assay number, date received, report date, and product‑specific information (CAS number, quantity, identity, purity percentage, and appearance).

Each COA includes the lead chemist’s signature from the testing laboratory and the testing methodology used. Product photos show the actual vial appearance and labeling for verification.

Research applications typically require 95% to 99%+ purity for reliable results. Lower purity can introduce variables that interfere with in vitro studies and compromise data integrity.

Our 99%+ purity variants meet pharmaceutical‑grade standards. Higher purity reduces experimental noise and provides cleaner baselines for your research protocols. Only purchase peptides from trusted sources that guarantee this level of purity.

Proper storage is essential. Peptides can be kept at room temperature as long as they are protected from light, heat, and moisture. For long‑term storage of lyophilized peptides, keep them at −20°C in their originally sealed vials. In all situations, keep them away from heat, light, and moisture.

Under these conditions, our research‑grade peptides maintain stability for 3 to 5 years. A sealed, desiccant‑protected environment preserves molecular integrity for long‑term laboratory use.

Reconstituted solutions remain stable for 3 to 4 weeks at 2–8°C. For longer storage, create small aliquots and freeze at −20°C or −80°C.

Avoid repeated freeze–thaw cycles, which can cause loss of peptide functionality. Always use sterile bacteriostatic water and aseptic technique when preparing solutions for multi‑use research applications.

Most in‑stock peptides with orders placed by 2:00 p.m. ship the same day; after this time, the next business day. Delivery times vary by region. On the product page, enter your local ZIP/postal code (CEP) to view shipping rates and estimated timelines.

All lyophilized peptides are shipped at ambient temperature in specific protective packaging to ensure the integrity of the vials and their contents.

Research peptides sold “for research purposes only” are considered legal in most jurisdictions when clearly labeled for laboratory use.

In Brazil, purchasing peptides for research purposes (i.e., use in scientific laboratories, in vitro analyses, or academic projects) is not automatically prohibited, provided the research purpose is clear and the substances are not registered as medicines or prohibited by Anvisa.

However, Brazilian law does not have a statute that specifically regulates “research peptides,” which makes their commercialization, exclusively for research purposes, legal.

This notice indicates that our peptides are scientific‑grade compounds intended only for laboratory applications. They have not been evaluated by ANVISA for human safety or efficacy.

We maintain strict regulatory compliance. All products are manufactured and labeled for scientific research purposes under International Good Manufacturing Practices, including within FDA regulations (Food and Drug Administration).

Peptides sold by Biopelabs in Brazil are intended exclusively for scientific research, such as laboratory studies, in vitro analyses, or academic development. They are not approved for human or animal use, nor for therapeutic, aesthetic, or performance purposes.

Any use outside the research context:

• Is not recommended,
• Is not authorized,
• And occurs under the full responsibility of the user, without any endorsement, guidance, or warranty from Biopelabs.

Improper use may:

• Violate current sanitary and regulatory standards,
• Involve unknown health risks,
• Characterize misuse of the product.

For this reason, Biopelabs does not provide instructions for use, dosages, or clinical guidance, reinforcing its commitment to scientific ethics, applicable legislation, and safety.

By purchasing a Biopelabs product, the buyer acknowledges that it is intended exclusively for scientific research.

Due to the characteristics of the products sold, Biopelabs does not offer direct installment payments at checkout. The only accepted Brazilian payment method is PIX.

However, some banks offer a “PIX in installments” modality, allowing customers to arrange installments directly with their financial institution according to the bank’s terms and rules.

Due to temperature‑sensitive storage requirements and the nature of research compounds, as well as transport conditions, we do not accept returns of peptides once they have been shipped (with tracking code).

Email contato@biopelabs.com with questions about products, technical specifications, or order assistance. We respond within 24–48 business hours.

Delays or issues may occur due to Correios operational factors. In such cases, we recommend contacting the Correios customer service center or visiting a nearby branch with your tracking code.

We guarantee dispatch within our company’s established timeframes. However, we are not responsible for losses or logistical failures attributable to Correios. If this occurs, the customer must open a ticket with Correios to request reimbursement of the product value, as indicated in the content declaration.
