What Researchers Say
"Purity consistency across batches has been outstanding. 22EXO is our go-to supplier for BPC-157 and CJC-1295 work."
"third order. consistent. consistent. consistent. that's the whole review honestly"
"Switched after my old vendor ghosted my COA request twice. 22EXO sent the COA before the package shipped. That's all I want."
"BETTER THAN THE BIG NAMES. Last lot from one of the big suppliers came in with discoloration. 22EXO's was textbook white. Done with the others."
"We see complete and intact 176-191 sequence on tandem MS. No truncation products at detectable levels. Quality control here is clearly tight."
"99.3% on our incoming HPLC, MALDI-TOF identity confirmed in-house. Documentation arrived attached to the order email, no chasing. Will reorder."
Built by Researchers,
for Researchers
If it isn’t pure enough for our own lab, it doesn’t leave the building. Every vial gets the same answer. Every researcher gets the same answer.
22EXO was founded in 2022 by a team of four researchers who were tired of inconsistent peptide quality, missing documentation, and suppliers that treated research compounds like an afterthought. So they built the company they wished existed: one where every batch is HPLC-verified, every order ships with a full COA, and every vial meets the standard they would demand for their own lab.
Today we operate out of our Jessup, PA facility with a growing catalog of 30+ research-grade compounds, cold-chain logistics, and a support team that actually understands what you’re researching.

The questions researchers ask before buying, with straight answers
What purity level do your peptides have?
All 22EXO peptides are synthesized to a minimum purity of 98%, verified through HPLC and Mass Spectrometry analysis. A Certificate of Analysis is available for every product.
How should I store peptides?
Lyophilized peptides should be stored at -20°C for long-term stability. Once reconstituted, store between 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles.
Do you offer international shipping?
We currently ship within the United States with express and standard options. Orders over $200 qualify for free domestic shipping. International researchers should contact us for custom logistics.
Are these peptides for human consumption?
No. All 22EXO peptides are sold strictly for in-vitro research and laboratory use only. Not intended for human or animal consumption, therapeutic use, or any diagnostic purpose.
Can I get a Certificate of Analysis?
Yes. Every batch has a corresponding COA documenting purity, mass spec verification, sequence confirmation, and lot identifier. Request it through your order page or contact our support team.
How long does shipping take?
Same-day dispatch on orders placed before 2 PM ET (Mon–Fri). Standard domestic delivery is 2–3 business days. Express overnight is available at checkout. We ship from our facility in Jessup, Pennsylvania.
What payment methods do you accept?
Major credit cards processed through a PCI-compliant gateway, plus cryptocurrency payments (BTC, ETH, USDC, SOL, and others) via NOWPayments. Crypto orders receive an additional discount.
How do I reconstitute lyophilized peptides?
Most peptides reconstitute cleanly in bacteriostatic water or sterile saline. Inject solvent slowly down the side of the vial — do not shake. Swirl gently until dissolved. See our reconstitution guide in the Knowledge Base for compound-specific instructions.
What is the difference between BPC-157 5mg and 10mg?
Same active compound, just different vial concentrations. The 10mg vial is more economical per milligram for extended dose-response protocols. Both ship lyophilized in 3 mL multi-dose vials with identical purity specifications.
Do you sell GLP-1 agonists like semaglutide?
No. We do not stock semaglutide, tirzepatide, or any GLP-1 receptor agonists. Our catalog focuses on research peptides with clean regulatory and safety profiles for in-vitro investigation.
What is your replacement policy?
If a product fails to meet specification or arrives damaged, we replace it free — no questions, no return shipping required. Contact support with your order number and a brief description.
Are your peptides cold-shipped?
Yes. All temperature-sensitive peptides ship with cold packs in insulated packaging. Lyophilized peptides remain stable at room temperature during transit, but we use cold-pack shipping by default for added stability margin.
We don’t cut corners. We don’t cut prices on quality. And we don’t leave researchers waiting on answers. Three rules. Every order. No exceptions.
