Why researchers get burned by peptide suppliers.
Purity on the label, not in the vial
Most suppliers grade their own product. The “≥99%” on the label was never checked by anyone outside their own building.
OUR ANSWER: Every NeoPep lot is verified by an independent, accredited lab before it’s released.
One generic COA for every lot
A certificate that never changes between batches is marketing, not documentation. It says nothing about your vial.
OUR ANSWER: Your COA is generated for your exact batch: identity, purity, potency, endotoxins.
Degraded before it arrives
Peptides are temperature- and light-sensitive. Shipped in a plain mailer, your compound can be compromised before it reaches the bench.
OUR ANSWER: Insulated phase-change packaging. Light-protected. Temperature-controlled from dispatch to door.
Nowhere to turn when it’s wrong
If a cheap vial fails testing, most suppliers stop answering. You’ve lost the money and the research time.
OUR ANSWER: If independent testing fails a sealed vial, we pay 200% of the product cost. In writing.
What researchers study peptides for.
You already know the science. Here’s which compound maps to which research area. Every one verified, documented, and ready to ship.
TISSUE REPAIR & RECOVERY RESEARCH
The most-requested compounds in connective-tissue and injury-recovery studies, investigating angiogenesis, growth-factor signaling, and repair cascades.
METABOLIC & BODY-COMPOSITION RESEARCH
Studied for their effects on appetite signaling, insulin sensitivity, and energy balance: the frontier of incretin and multi-agonist research.
MITOCHONDRIAL & ENERGY RESEARCH
A mitochondrial-derived peptide investigated for metabolic regulation, exercise capacity, and cellular energy homeostasis.
GH-AXIS & VITALITY RESEARCH
Pulsatile secretagogues used to study growth-hormone release patterns, body composition, and age-related decline in lab models.
SKIN & CELLULAR RESEARCH
A copper peptide examined for collagen synthesis, wound-healing pathways, and gene-expression changes in dermal models.
NEUROACTIVE & SEXUAL-HEALTH RESEARCH
A melanocortin-receptor agonist studied for its effects on sexual function and central nervous system pathways.
Why NeoPep Research exists.
We started NeoPep Research because we were tired of watching research get compromised by underdosed, mislabeled, and undocumented peptides. Verification isn’t a feature here. It’s the entire business.
Every compound is synthesized in U.S. facilities, independently verified to ≥99% purity by HPLC and mass spectrometry, and released only with a batch-specific Certificate of Analysis. If a lot doesn’t pass, it doesn’t ship. No exceptions.

FROM LAB TO VIAL
Synthesis
Every peptide is produced via automated solid-phase peptide synthesis (SPPS), ensuring uniform molecular sequences across every production run.
Independent Verification
Before any lot ships, it goes to a third-party, accredited lab for identity confirmation (mass spectrometry), purity analysis (HPLC), potency quantification, and endotoxin testing. If it doesn’t meet 99%, we don’t release it.
Batch-Specific COA
Every released lot gets its own Certificate of Analysis. Not a representative sample, not a generic sheet. The documentation reflects the exact material in your vial.
Cold Chain Dispatch
Lyophilized peptides ship in insulated, phase-change packaging. Temperature-controlled storage. Light-protected. Every vial is expiration-dated.
FOR RESEARCH USE ONLY
All products are supplied strictly for in-vitro laboratory research by qualified professionals. Not for human or veterinary use. These products have not been evaluated by the FDA and are not intended to diagnose, treat, cure, or prevent any disease.
COMMON QUESTIONS
What purity level are your peptides?
We require a minimum purity of 99%. If a production lot does not meet that threshold, we do not release it. Every lot undergoes independent third-party verification before release.
What is a Certificate of Analysis (COA)?
A COA is a verified report from an independent laboratory documenting the material in one specific production lot. Start with the lot number, then review identity, purity, potency, and endotoxin results.
How fast do you ship?
Orders placed before 10:00 a.m. PT on business days are dispatched the same day. Free 2-day expedited shipping on orders over $200.
Do you offer free shipping?
Yes. Orders over $200 receive complimentary 2-day expedited shipping via UPS 2nd Day Air or comparable service.
Are your products for human use?
No. All products are supplied strictly for in-vitro laboratory research by qualified professionals. They are not for human or veterinary use and have not been evaluated by the FDA.
