Frequently Asked Questions

Research Use Only (RUO) means our peptides are intended exclusively for use in controlled laboratory and research settings by qualified scientists. They are not approved by the FDA for any therapeutic use, not intended for human or animal consumption, and not to be used as drugs, supplements, or medical devices. By purchasing, you confirm you are a qualified researcher using compounds only for lawful research purposes.

In the United States and most countries, research-grade peptides sold for legitimate research purposes are legal to purchase. However, regulatory status varies by jurisdiction and compound. It is your responsibility to verify the legal status in your country before purchasing.

No. All Bliss Peptides products are sold strictly for laboratory and research use only. They are not drugs, supplements, or for human or animal consumption, dosing, injection, or ingestion. Any order indicating intent for human use will be cancelled and the account suspended.

Every batch undergoes: (1) In-house HPLC for purity assessment, (2) Mass Spectrometry for molecular weight confirmation, (3) Third-Party HPLC by an external ISO 9001:2015-certified lab, and (4) Endotoxin Testing via LAL assay. No product ships without passing all four stages.

The full Certificate of Analysis for each product is published right on its product page — open the product and select the "Certificate of Analysis" tab to view or download the watermarked PDF. Every COA includes lot number, test date, HPLC chromatogram data, MS spectrum, and endotoxin results.

Our catalog minimum is ≥98% purity by HPLC. The vast majority of our products are ≥99%. The exact purity for each product is listed on the product page and your lot-specific COA contains the precise measurement. We do not sell batches below stated minimums — they are destroyed.

We accept Visa, Mastercard, American Express, ACH/bank transfer (orders over $200), and cryptocurrency (Bitcoin, Ethereum, USDT, USDC, and 40+ coins — 5% discount applied automatically). All card payments are processed through PCI-compliant infrastructure.

No minimum order. You can purchase a single vial. Orders over $150 qualify for free standard shipping. Bulk orders (10+ vials of the same product) receive a 10% discount. Contact us for pricing on larger research quantities.

Orders can be modified or cancelled within 2 hours of placement by contacting blisspeptides@proton.me. After this window, orders enter our fulfillment queue and cannot be altered.

All peptides ship lyophilized (freeze-dried) in discreet, insulated packaging. Lyophilized peptides are stable at ambient temperature for the duration of transit, so no refrigeration or ice packs are required. We recommend refrigerating your vials once they arrive.

Standard ($9.99, free over $150): 3–5 business days. Express ($18): 1–2 business days. Overnight ($39): next business day by 12pm. We ship within the United States only. All orders are dispatched within 1–2 business days of payment confirmation.

Lyophilized peptides: store at -4°F long-term, 39°F for up to 1 month. After reconstitution: 39°F for up to 1 week, or -112°F for longer. Avoid repeated freeze-thaw cycles. Keep vials sealed until use.

Lyophilization (freeze-drying) removes water from the peptide while preserving its molecular structure, dramatically extending shelf life (2–3 years vs weeks in solution) and providing greater stability during shipping. All Bliss Peptides products ship as lyophilized powder.

No. We only offer the compounds listed in our catalog, and every product ships with a published third-party Certificate of Analysis. We do not provide custom synthesis or source compounds outside our verified, tested inventory.

We cannot accept returns of opened vials. However: damaged in transit receives full replacement or refund (contact us within 48 hours with photos); wrong item shipped receives full replacement at our expense; unopened vials may be returned within 7 days with authorization.
