HPLC & MS Verified: ≥99% lab purity guaranteed on every lot.
01 What are your products intended for?

All peptides, proteins, and biochemical reagents supplied by Peptide Giants are synthesized strictly for in-vitro laboratory research and scientific educational purposes.

⚠️ Research Notice: Our products are not intended for human or veterinary administration, drug manufacturing, or cosmetic formulation. Purchasers must be authorized researchers.
02 Do you provide Certificates of Analysis (COAs)?

Yes. Every batch is independently tested by 3rd-party US laboratories to guarantee verifiable scientific purity:

✓ HPLC Chromatography Confirms minimum 99%+ peptide purity.
✓ Mass Spectrometry (MS) Verifies exact sequence identity & mass.

COAs are downloadable on individual product pages or upon request by referencing your batch lot number.

03 How long does shipping take after placing an order?

Orders received before 2:00 PM EST (Monday – Friday) are dispatched on the same business day from our climate-controlled US fulfillment center in Florida.

Standard domestic courier shipping typically arrives within 2 to 4 business days. Tracking details are emailed immediately once the package is scanned by the carrier.

04 How should peptides be stored?

Proper storage is essential to preserve peptide integrity and biological activity:

❄️ Lyophilized (Powder) Stable at room temp during transit. Store long-term at -20°C protected from light and moisture.
🧪 Reconstituted (Solution) Refrigerate at 2°C to 8°C. Avoid repeated freeze-thaw cycles.
