About Peptidology
Written by the company
Peptidology is different in three ways.
1. Product
Our 14-point advanced testing protocol covers up to 27 units per batch — more than any other firm we're aware of. Every product exceeds 99% purity, and its contents are identified and confirmed. Up to 9 units per batch are tested for sterility and screened for common heavy metals, including chromium, arsenic, cadmium, and lead.
Using ion chromatography, we screen for manufacturing byproducts such as trifluoroacetic acid (TFA), and we test for 15 industrial solvents commonly used in production, including benzene.
We also screen for endotoxins (also known as LPS, or lipopolysaccharides). Container closure integrity is verified using the dye-ingress method to confirm each vial's contents remain intact, and solubility analysis confirms every product is stable and reconstitutes properly.
Every batch is tested by our U.S.-based analytical partners, Vanguard Laboratory and Eagle Analytical — both ISO-certified, inspected facilities. Batch-level QR codes appear on every product, with all current and past certificates available on demand.
Our Certificate of Analysis Manager is the best in the industry — searchable by batch and compound, and it tracks purity levels over time.
Raw materials are manufactured by FDA-audited suppliers and finished in GMP-compliant laboratories.
2. Service
Our Arizona-based support team is available by phone at (480) 974-4660 during business hours, Monday through Friday, 9 a.m. to 5 p.m. Live chat is available on our website. We ship six days a week from a warehouse located minutes from a major shipping hub. Place an order by 2:30 p.m. Arizona time on weekdays and it ships the same day.
We accept all major cards and bank transfers, offer bulk order discounts, and back every purchase with a 60-day return policy.
3. Industry discounts
We offer special discounts to Defense and Veterans Affairs institutions, federal and municipal government agencies, and public safety and emergency response organizations. This initiative supports these vital professions while expanding their access to high-quality research materials. Learn more about industry discounts here.

Product is great! Delivery was not, product showed up 2 days later than expected. It was my 1st order so luckily it wasn't a major issue.

Peptidology is Unmatched!
Transparency with the quality and testing of their peptides is unlike anywhere else I have found! I did extensive research on all the different companies (over 100 hours) and this was by far the most reputable and best reviewed company! Both labs are FDA accredited and have reports available through them, as well!
If you’re getting started and feel overwhelmed eith all of the different companies, go with Peptidology! Shipping is fast, quality is unmatched, and prices are more than reasonable.
They always offer some sort of discount, so you are always saving money! Purchased GLP-3 (Retatrutide) 5 mg from them starting at a 1 mg dose, and I am already down 3 pounds in less than a week. Excited to continue my health journey with Peptidology!

Quick shipment
Quick shipment! Fedex always seems to push delivery date back by one or 2 days. Sadly. Great products, feel the changes. Better discounts would be great. Better discounts more repeat customers. Find a way to keep customers away from WhatsApp.

Peptidology seems to have good…
Peptidology seems to have good products. Sometimes, there is limited supply, especially when there are sales. There was a quality control issue with BPC-157, where when removing the cap, it tore off a portion the top of the aluminum on the vial, exposing the peptide vial with an improper seal. I was told to start at the "arrow" which made no difference. This happened with 3 different vials so far. I brought it to their attention, so hopefully, this is resolved. They were good about replacing the defective vials. I continue to purchase many peptides from Peptidology.

Hi David, we appreciate your feedback and purchases! We did have a batch of product that had directional caps that seemed problematic. We'll call it a failed experiment. We're working to ensure more products aren't released that way. I'm sorry for the trouble and the extra time in having to seek a resolution. Best, Josh
