What are research peptides and are they legal to buy?
Synthetic amino acid chains sold legally in the US as research chemicals for laboratory use only. Not for human or animal consumption.
Do your products come with a Certificate of Analysis (COA)?
Yes — every product ships with a third-party Certificate of Analysis confirming 99%+ purity, posted on each product page.
What time do I need to order for same-day shipping?
Order before 3:00 PM CST on any business day and it ships same day from Wisconsin. Tracking included on every order.
How should I store my peptides after they arrive?
Keep lyophilized vials refrigerated at 2–8°C. Once reconstituted, use within 30 days. Freezer storage at -20°C extends shelf life to 12–24 months.
What is Bacteriostatic Water and why is it used with peptides?
Sterile water with 0.9% benzyl alcohol used to reconstitute lyophilized peptides. Keeps your solution stable for up to 30 days refrigerated.

Are Evo Peptides products tested for purity?

Quality you can verify, not just trust
Every batch is independently tested by accredited third-party laboratories. We don't ask you to take our word for it — we give you the proof.
Every vial is tested by HPLC to confirm it contains exactly what the label says — down to the microgram.
Why it matters: No guessing. You get the exact concentration you paid for, confirmed by an independent lab every batch.
Mass spec testing confirms peptides are free from impurities, synthesis byproducts, and degradation — every batch, not spot-checked.
Why it matters: Impurities corrupt research outcomes. MS gives a molecular fingerprint that can't be faked.
Formulation and pH testing ensures every batch stays intact through its labeled shelf life — not just at the moment it ships.
Why it matters: A peptide that degrades in storage is a wasted experiment. Stability data gives you confidence in what you're working with.
Precision weighing and QC controls ensure every batch meets the same standard. Your tenth order tests exactly like your first.
Why it matters: Reproducibility is the foundation of research. Inconsistent peptides produce inconsistent results.
