// why 5 star
We know what serious researchers need. Documented purity, fast shipping, and compounds that are what the label says they are.
Every batch is independently tested by accredited labs. We publish the results — no cherry-picking, no hiding failures.
Dual verification methodology. High-performance liquid chromatography combined with mass spectrometry for absolute confidence.
Every vial carries a lot number traceable to its synthesis date, raw materials, and full QC record. Full chain of custody.
Lyophilized peptides ship with cold packs and insulated packaging. We don't cut corners on the last mile.
FOR RESEARCH USE ONLY. All products sold by 5 Star Peptides are intended solely for in vitro research and laboratory use. Not for human or veterinary use, consumption, or diagnostic purposes. Not approved by the FDA. By purchasing, you confirm you are a qualified researcher and will use these compounds in accordance with all applicable laws and regulations.
// quality assurance
We don't ask you to trust us. We give you the data.
Synthesis & Purification
Solid-phase peptide synthesis (SPPS) followed by RP-HPLC purification to >98% minimum purity before QC testing.
Independent Lab Testing
Each batch sent to a third-party accredited laboratory. We have no control over results — just the commitment to publish them.
COA Download per Lot
Every order ships with the lot number. Use it to pull the full PDF certificate directly from our site at any time.
Batch Rejection Policy
If a batch doesn't meet our purity threshold, it never ships. Simple as that.
