Why Researchers Choose PrimaLab Peptide

The Research Standard You Should Expect

We exist to support legitimate laboratory research with verified, documented, and consistently pure research compounds. No shortcuts. No unverified batches. No marketing claims without data.

Independent Third-Party Testing

Every batch is sent to Janoshik Analytical, an independent European laboratory, before it ships. HPLC purity analysis and mass spectrometry identity confirmation on every product. The COA is batch-specific, tied to your order, and verifiable on the Janoshik database before you buy. Not a template. Not a stock certificate. Your actual batch result.

Research-Grade Purity Standard

PrimaLab Peptide maintains a minimum 99%+ purity standard across all research peptides. Low-purity compounds produce unreliable data, introduce experimental confounds, and waste research time and budget. Our purity floor is the standard every serious laboratory should demand from any peptide supplier.

Worldwide Research Delivery

We supply research peptides to laboratories, research institutions, clinics and distributors across 50+ countries worldwide. Every order is shipped in temperature-appropriate packaging with full tracking from dispatch to delivery. Wholesale accounts available for bulk research procurement.

Full Documentation on Every Order

Every PrimaLab Peptide order ships with a batch-specific Certificate of Analysis, full product specifications, sequence data, and storage guidelines. Complete documentation for your laboratory records, institutional audits, and research publication requirements.

Complete Research Peptide Catalog

From metabolic peptides including Semaglutide, Tirzepatide and Retatrutide, to healing compounds including BPC-157 and TB-500, to longevity research compounds including NAD+ and Epitalon, PrimaLab Peptide supplies one of the most comprehensive independently verified research peptide catalogs available worldwide.

Dedicated Wholesale Support

What Our Clients Say

Laboratories and research institutions across 50+ countries trust PrimaLab Peptide for verified, documented research-grade compounds. Buy research Peptides today
PrimaLab Peptide has become our go-to supplier for research-grade peptides. The Janoshik COA on every batch is non negotiable for our laboratory documentation requirements. Purity has been consistently above 99% across every order. Fast international dispatch and responsive support team.
Dr. M. Henderson
Research Biochemist
We source Semaglutide, Tirzepatide and Retatrutide regularly for our metabolic research program. The batch-specific COA and transparent Janoshik documentation make PrimaLab Peptide stand out from other suppliers we have worked with. Wholesale pricing is competitive and account management is excellent.
Dr. S. Eriksson
Principal Investigator — Metabolic Research
Reliable, documented, and consistently pure. We have been ordering BPC-157, TB-500 and the Klow Blend for our tissue repair research protocols for over a year. Every vial matches the COA. Worldwide shipping is fast and packaging is always appropriate for peptide stability during transit.
Prof. A. Nakamura
Laboratory Director
I have ordered from several peptide suppliers over the years and PrimaLab Peptide is the only one that consistently delivers what the label says. The COA matches the vial every single time. Ordered BPC-157 and TB-500, both arrived well packaged, clearly labelled with batch numbers, and purity was exactly as listed. Will not be going anywhere else.

Frequently Asked Questions

Everything researchers need to know about buying research peptides from PrimaLab Peptide.

Where can I buy research peptides online with a verified COA?

PrimaLab Peptide supplies research-grade peptides worldwide with a batch-specific Certificate of Analysis from Janoshik
Analytical included with every order. Every product is independently verified via HPLC and mass spectrometry before
dispatch. You can verify your batch COA directly on the Janoshik database before you buy, no trust required, just check the data.

Yes. Every single batch is independently tested by Janoshik
Analytical, an independent European analytical laboratory widely
used in the research peptide community. We do not self-certify.
Janoshik runs HPLC purity analysis and mass spectrometry identity
confirmation on every product. The COA is batch-specific, tied
to your exact lot number, and included with every order.

PrimaLab Peptide maintains a strict minimum 99%+ purity standard across our entire research peptide catalog. Exact purity figures are batch-specific and documented on the Janoshik COA included with your order. Low-purity compounds produce unreliable research data; our purity floor is the standard every serious laboratory should demand from any peptide supplier.

Yes. PrimaLab Peptide ships research peptides to laboratories
and research institutions across 50+ countries worldwide including
Europe, North America, Asia-Pacific, the Middle East and Africa. Every order ships with full tracking and temperature-appropriate packaging. Delivery timeframes vary by destination. See our Shipping Policy for full details.

BPC-157 and TB-500 are two completely distinct research peptides with different sequences, mechanisms and research applications. BPC-157 is a 15-amino acid pentadecapeptide derived from a gastric juice protein, studied for multi-system tissue repair, gastrointestinal protection and angiogenesis research. TB-500 is a 43-amino acid Thymosin Beta-4 acetate fragment studied for actin-mediated cellular migration, muscle regeneration and tissue repair. Many researchers study both together for complementary dual-pathway healing research, available as our BPC-157 + TB-500 Blend.

What is Semaglutide used for in research?

Semaglutide is a GLP-1 receptor agonist research peptide studied for GLP-1 receptor binding kinetics, glucose-dependent
insulin secretion mechanisms, central appetite and satiety pathway research, gastric emptying rate modulation, and as
the reference single-receptor GLP-1R comparator in multi- receptor agonist research alongside Tirzepatide (dual GIP/
GLP-1R) and Retatrutide (triple GLP-1R/GIP/glucagon). It
is available in 5mg and 10mg lyophilized vials with Janoshik
COA included.

Most research peptides are reconstituted using Bacteriostatic Water (BAC Water), add solvent slowly down the inside vial wall, never directly onto the powder, and swirl gently — never shake. IGF-1 LR3 requires Acetic Acid Water 0.6% for initial reconstitution. Store reconstituted peptides at 2–8°C and use within the timeframe specified on the product page. Full reconstitution guidance is provided on every product page, and all Reconstitution supplies are available in our Accessories section & Reconstitution Supplies section.

NAD+ (Nicotinamide Adenine Dinucleotide) is a critical cellular coenzyme studied for sirtuin (SIRT1-7) deacylase enzyme activation, PARP-mediated DNA repair signalling, electron transport chain redox reactions, mitochondrial biogenesis, circadian rhythm regulation, and age-associated NAD+ decline research. It is one of the most referenced compounds in longevity and cellular ageing research programs alongside SS-31 (Elamipretide), Epitalon, MOTS-c and
Glutathione. Available in 100mg, 500mg and 1000mg vials.

In most jurisdictions, yes, for legitimate laboratory research purposes. Research peptides are legal to purchase for qualified researchers and licensed laboratory professionals in most countries. They are not approved for human or veterinary use by the FDA or any equivalent regulatory agency. Buyers are solely responsible for verifying compliance with all applicable local laws and regulations
governing the purchase and use of research compounds in their jurisdiction before ordering.
