View DetailsWhat Are Research Peptides?
Peptides are short chains of amino acids — the same building blocks that form proteins in every living organism. In scientific research, synthetic peptides serve as powerful tools for studying biological mechanisms, from cellular signaling pathways to metabolic regulation and tissue repair processes.
At Pepitiva Biolabs, we specialize in providing research-grade synthetic peptides with verified purity of 98% or higher. Our catalog includes metabolic research compounds such as Tirzepatide, Retatrutide, and Semaglutide — dual and triple receptor agonists that have become essential tools in GLP-1 and GIP pathway research. We also supply regeneration peptides, neuropeptides, longevity compounds, and endocrine research tools.
Every compound in our catalog is synthesized using solid-phase peptide synthesis (SPPS) methodology, purified through reverse-phase HPLC, and verified by electrospray ionization mass spectrometry (ESI-MS). The result is a lyophilized powder of exceptional purity, supplied with a complete Certificate of Analysis (COA) documenting identity, purity, and molecular weight confirmation.
From Synthesis to Your Laboratory
Synthesis & Purification
Each peptide is synthesized using solid-phase peptide synthesis (SPPS) and purified via reverse-phase high-performance liquid chromatography (RP-HPLC) to achieve purity levels of 98% or greater.
Analytical Verification
Identity and purity are confirmed through HPLC analysis and electrospray ionization mass spectrometry (ESI-MS). A detailed Certificate of Analysis (COA) is generated for every batch.
Lyophilization & Packaging
Purified peptides are lyophilized (freeze-dried) to ensure long-term stability. Each vial is sealed under inert atmosphere and labeled with batch number, purity, and storage instructions.
Thermal-Protected Shipping
Orders are processed within 24 hours and shipped in insulated packaging with cold packs to maintain product integrity during transit. Free shipping is available on bulk orders of 5 or more units.
Our Commitment to Purity
Quality is not just a feature at Pepitiva Biolabs — it is the foundation of everything we do. We understand that the reliability of your research depends on the quality of your reagents, which is why we maintain the highest standards of analytical verification for every compound we supply.
Our quality assurance protocol includes multi-point HPLC purity analysis, mass spectrometry identity confirmation, endotoxin testing for select compounds, and visual inspection of lyophilized product consistency. We reject any batch that does not meet our strict 98%+ purity threshold, ensuring that researchers receive only the highest quality materials for their studies.

Frequently Asked Questions
Are Pepitiva Biolabs peptides for human use?
No. All our products are intended exclusively for scientific research purposes (Research Use Only). We do not sell products for human or veterinary use.
How is peptide purity guaranteed?
Each batch undergoes HPLC (High Performance Liquid Chromatography) analysis and mass spectrometry. We provide Certificates of Analysis (COA) for all products.
What is the shipping time?
Order processing takes up to 24 hours. Shipping is done with specialized thermal packaging to ensure product integrity during transport.
How does the affiliate program work?
After registration, you receive an exclusive affiliate link. For each sale made through your link, you earn a commission. Payment is monthly via PIX and you can track everything through the affiliate dashboard.
What peptide categories does Pepitiva offer?
Our catalog covers six research categories: Metabolic peptides (Tirzepatide, Retatrutide, Semaglutide, AOD-9604), Regeneration compounds (Glow, Klow), Endocrine research tools (CJC-1295 + Ipamorelin), Longevity peptides (MOTS-c, SS-31, NAD+, Epithalon), Neuropeptides (Selank, Slupp332), and essential accessories including Bacteriostatic Water and Vitamin B12.
What is the Certificate of Analysis (COA)?
A Certificate of Analysis is an official document that accompanies each batch of peptide, reporting the results of analytical testing including HPLC purity percentage, mass spectrometry molecular weight confirmation, appearance, and storage conditions. The COA provides researchers with the transparent data they need to validate their experimental protocols.
Do you offer bulk pricing and discounts?
Yes. We offer tiered bulk discounts: 5% off on orders of 3 or more units, 10% off plus free shipping on orders of 5 or more units, and 15% off plus free shipping on orders of 10 or more units. These discounts apply automatically at checkout and can be combined across different products in our catalog.
How should research peptides be stored?
Lyophilized peptides should be stored at -20°C (freezer) for long-term stability. Once reconstituted, peptide solutions should be stored at 2-8°C (refrigerator) and used within the timeframe specified in the product documentation. Avoid repeated freeze-thaw cycles as this may degrade peptide integrity.
