- STEP 01
Choose your compound
Browse HPLC-tested research peptides and narrow by application, purity, or target pathway.
- STEP 02
Confirm the COA
Open the batch Certificate of Analysis before you buy — third-party results and mass-spec data included.
- STEP 03
Receive lab-ready stock
Shipped cold-chain and lyophilized so it arrives stable, labeled, and ready for your protocol.
Testing standards
One vial. Three tests.
Most vendors test purity and stop. We verify purity, actual content, and endotoxins on every batch, then publish the certificate.
Purity
RP-HPLC >99% by area
Every batch is assayed by reverse-phase HPLC so you know the dominant peak — not a label claim.
Content
Confirmed peptide content
We verify actual peptide mass in the vial, so dosing math matches what arrives at your bench.
Endotoxin
Low EU/mg, lab-reported
Endotoxin levels are measured and published per lot — research-ready without guessing contamination risk.

Why Biologix
Not all peptides are created equal.
Biologix started from a simple frustration: finding reliable, documented research peptides shouldn't be this hard. Every batch we sell is third-party tested. Every Certificate of Analysis is published before purchase.

24/7 Support
Round-the-clock customer service for any questions before or after your order.
Yes. Each batch ships with a Certificate of Analysis from independent testing, including HPLC and mass spectrometry data. You can also review COAs on the product page before checkout.
Orders leave our facility in insulated packaging with cold packs through carriers set up for temperature-sensitive research materials. Most U.S. deliveries arrive in 2–5 business days, with faster options available at checkout.
We accept major credit and debit cards at checkout through our secure payment partner. Your card statement may show a billing descriptor from the payment processor rather than Biologix.
Every lot is screened by a third-party lab. We require HPLC purity of at least 98%, and mass spectrometry is used to verify molecular weight and compound identity. Those results appear on the COA for each batch.
Keep lyophilized vials at −20°C for long-term holding. After you reconstitute, refrigerate at 2–8°C and follow the use window in the product documents. Limit freeze–thaw cycles to protect integrity.
If a shipment does not match the purity stated on its COA, we will replace it at no cost. Eligibility and next steps are outlined in our refund policy.
Compounds arrive lyophilized (freeze-dried) in sealed glass vials so they stay stable in transit and storage. Reconstitution guidance is included with every package.
We fulfill primarily within the U.S. For international research labs, reach out through our contact page with your location and compound list — we will confirm whether we can ship to your region and what lead times apply.
Yes. Labs and repeat buyers can request volume pricing. Email research@biologix.com with the compounds and quantities you need, and we will send a tailored quote.
Biologix materials are sold only for in vitro research and laboratory use. They are not for human or veterinary use. Purchasers are responsible for following all local, state, and federal rules that apply to them.
