How much do research peptides cost?
Catalog peptide pricing at PeptidesDirect runs from $34 for single-vial bioregulators to $329 for the largest GLP-1 vials. Larger vials cost less per milligram, so compare cost per mg rather than price per vial. The pricing page lists the exact price and cost per mg for all 131 strength options.
Which peptides are for sale at PeptidesDirect?
The catalog lists 106 research peptides for sale across 11 categories: GLP-1 & metabolic, growth hormone secretagogues, recovery & repair, growth factors, reproductive, melanocortin, cognitive, longevity, immune, bioregulators and specialty blends. Best sellers include BPC-157, TB-500, Semaglutide, Tirzepatide, Retatrutide and GHK-Cu.
Is there a discount on peptide pricing?
Yes. Every order paid with cryptocurrency (Bitcoin, Ethereum, Tether or USD Coin) receives an automatic 10% discount at checkout. The pricing page calculator shows the crypto price next to the list price for every strength.
Do you offer bulk or wholesale peptide pricing?
Yes. Laboratories, universities and high-volume researchers can request a custom bulk quote covering quantity pricing, lead time and COA documentation via the contact page.
How do I know the peptides are genuine?
Products carry a ≥98% HPLC purity standard. Where a lot-specific Certificate of Analysis is available, match its product, strength, and lot identifiers to the vial and carton before reading the HPLC and LC-MS results.
What payment methods can I use to buy peptides?
PeptidesDirect accepts Bitcoin, Ethereum, Tether (USDT) and USD Coin (USDC), with a 10% discount on all crypto payments. Payment options can change; the checkout page always shows the currently available methods.
How are peptides shipped and stored?
Peptides ship lyophilised (freeze-dried) in cold-chain packaging for stability in transit. Store lyophilised vials refrigerated or frozen, and follow the storage and reconstitution guides after mixing.
Can I track my order after buying?
Yes. When your order ships you receive a confirmation email with the carrier and tracking number, and you can check status any time on the public tracking page with your order number and checkout email.
What should I research before choosing a peptide?
Start with the complete peptides guide for how research peptides are made, tested and handled, then read the compound-specific research guide — we publish cited science guides for Tesamorelin, KPV, NAD+, SS-31, Selank, Semax, Ipamorelin and the CJC-1295/Ipamorelin blend, plus side-by-side comparisons.
How do I place an order?
Pick a peptide and strength in the shop, add it to your cart and check out with your shipping address. You receive a confirmation email with your order number and ship date, and you can follow the parcel on the public tracking page.
When will my order ship?
Order before 1:00 PM Central on a business day and your order ships the same day — the exact dispatch date is shown on every product page and in your confirmation email. A tracking link follows by email when the label is created.
How should I handle peptides when they arrive?
Store lyophilised vials refrigerated or frozen, away from light and moisture. Reconstitute with bacteriostatic water using sterile technique and refrigerate solutions at 2–8°C. The reconstitution, bacteriostatic water and storage guides cover each step.
Are these peptides for human use?
No. All products sold by PeptidesDirect are strictly for in-vitro laboratory research use only. They are not for human consumption, therapeutic use, veterinary use, or any in-vivo application.
