Frequently Asked Questions
About PeptideBudget
A price comparison is only useful if it's correct. Here's how we keep ours honest.
What is PeptideBudget?
PeptideBudget is a free price comparison tool for research peptides. We track pricing and stock across curated vendors to help you find the best options quickly.
How do you keep prices accurate?
We use custom scrapers built for each vendor (not a generic crawler). Prices refresh multiple times daily, but always confirm current pricing and stock on the vendor's site before ordering.
How often are prices updated?
Multiple times per day. We still strongly recommend verifying the latest details directly on the vendor's website.
How do you choose which vendors to list?
We only include vendors with transparent pricing and solid testing practices (COAs). Quality and reliability matter more than quantity.
How do you handle Certificates of Analysis (COAs)?
We check that vendors provide COAs, but we don't host or verify them. Always review the latest COA for your batch directly on the vendor's site.
What makes PeptideBudget different?
- Curated vendor list (quality over quantity)
- Custom per-vendor scrapers for better accuracy
- Advanced Shop Calculator – build a multi-peptide cart and instantly see the cheapest vendor combination or split purchase
- No pay-to-play rankings or sponsorship bias
How are products ranked?
You can sort by price, name, or popularity. Rankings are not influenced by payments or sponsorships.
I found a price that looks wrong. What should I do?
Please report it via the contact form with the vendor, product, and link if possible. We'll check it quickly.
