Lab Notes
Plain-language notes on reading a certificate of analysis, HPLC and mass spectrometry, salt forms, freeze-drying and storage. Free to read, no account needed.
Reading a certificate
The lab, the lot, the method beside the values, and what a missing result means.
Reading a certificate
Retention time, peaks and area percent, and why area percent is not mass percent.
Reading a certificate
Charge states and deconvolution, and why a correct mass says nothing about purity.
Quality and chemistry
Why a powder can read 99% by HPLC and still be far from 99% peptide.
Quality and chemistry
Solid-phase synthesis step by step, and where the impurities come from.
Handling science
Freeze-drying, sublimation, the cake, and why dry material changes slowly.
Handling science
How heat, light and moisture change dry material, and why the rule is cold, dark and dry.

Where a product has a third-party certificate, its product page shows the lab, method, and test date. Lowest price, guaranteed: find the same research compound cheaper from a U.S. supplier, send support a screenshot and the link, and once support confirms it, we match the lower price.
Why Banana Peppers
Banana Peppers supplies research-use-only compounds for laboratory and analytical work. Every product is labeled by product code and dose, priced with no checkout surprises, and shipped from the United States. Where a product has a certificate of analysis its page summarizes it per batch and by method, not as a blanket catalog claim; the certificate opens with a free account.
Our products are sold for research and identification purposes only. They are not intended for human dosing, injection, or ingestion.
What You Can Check Before You Order
Specific, checkable facts. What has not been tested is stated as plainly as what has.
01
Where a product has a certificate of analysis from an independent lab, its product page shows the purity figure with its method, the lab, the batch and the test date, and links the certificate. Sterility and endotoxin are not tested unless a certificate states it. Where a product has no certificate, its page says COA not currently available.
02
Every priced size shows its price per milligram. No hidden checkout fees; shipping is quoted by ZIP code before you pay. Find the same research compound cheaper from a U.S. supplier, send support a screenshot and the link, and once support confirms it, we match the lower price.
03
Orders ship from the United States with tracking emailed to you. Confirmed orders usually ship within 24 hours, and always within 1-2 business days. Technical questions are answered by email at info@bananapeps.com before you buy.
The Banana Peppers Promise · Lowest Price, Guaranteed.

Verify what has been tested. Where a product has a certificate of analysis from an independent lab, its result is reported by method and per batch, not as a blanket catalog claim. Certificates we have published are open to read in the COA library with a free account.

Answers to the questions researchers ask before their first order.
All products sold on this website are intended for laboratory research and identification purposes only. They are not intended for human dosing, injection, or ingestion, and nothing on this site is intended to diagnose, treat, cure, or prevent any condition. If you are not a researcher purchasing for these purposes, these products are not for you.
Where a certificate is published and its purity reading has been confirmed for a size, the product page shows that size’s purity figure with its method, tied to that batch (for example, “99.82% by HPLC-UV/MS, batch 0726”), the lab, the batch and the test date. Every published certificate is linked from its product page. Purity is reported by HPLC; where the method lists MS, mass confirmation is reported as well. Sterility and endotoxin are not tested unless a certificate states it. A product without a published certificate says so on its page and shows no purity figure, so you can make your own decision.
Orders ship from the United States. Confirmed orders usually ship within 24 hours, and always within 1-2 business days. Tracking is emailed when the order leaves. Shipping is quoted by ZIP code and service at checkout, before you pay. Lyophilized compounds are held in cold storage until they ship and are stable at ambient temperature in transit; storage notes are listed per product. All sales are final once shipped: if an item arrives wrong, visibly damaged, or demonstrably defective, email info@bananapeps.com within 5 business days of delivery with photos, and we will, at our discretion, replace or issue credit. Orders can be cancelled for a full refund any time before shipment. Full terms: Shipping & Refunds.
Yes. Lowest price, guaranteed. Find the same research compound cheaper from a U.S. supplier and send support a screenshot and the link. Once support confirms it is the same compound from a U.S. supplier, we match the lower price.
