Built on Integrity.
Backed by Science.
Five non-negotiable commitments we make to every researcher who places an order. These aren't marketing claims — they are operational standards we are accountable to, batch by batch, order by order.
Our Five Promises
- Independently Verified Purity
>98% HPLC Purity. Every Batch. No Exceptions.
Every compound we ship is analysed by a certified third-party laboratory using High-Performance Liquid Chromatography (HPLC) before it leaves our facility. If a batch doesn't clear 98%, it never ships. Your research data is only as reliable as the compounds you start with.
We test for: identity confirmation (mass spectrometry), purity (HPLC-UV), and the absence of residual solvents and heavy metals.
- Certificate of Analysis on Every Order
No COA? No Sale. It's that simple.
A Certificate of Analysis (COA) accompanies every single order — not just select batches, not just on request. Your COA documents the lot number, testing date, purity result, and identity confirmation for the exact vials you receive.
You can cross-reference your lot number on our website at any time. If you can't verify it, contact us immediately.
- Cold-Chain, Discreet Shipping
Temperature-Controlled. Shipped Fast. Arrives Right.
Peptides are biologically active compounds. Heat, light, and moisture degrade them during transit. Every order is shipped in temperature-controlled packaging with desiccant, wrapped discreetly — no branding, no indication of contents.
In-stock orders Overnight and 2–3 day delivery available. Domestic delivery in 2–5 days. We absorb the cost of re-shipment if your order arrives damaged or compromised.
- Transparent, Consistent Pricing
No Hidden Fees. No Bait-and-Switch.
The price you see is the price you pay. We don't inflate prices to run fake sales. We don't charge handling fees at checkout. Pricing is updated based on actual market conditions — never inflated to manufacture discounts that aren't real.
Bulk discounts are structured and published on our Bulk Orders page. Academic institutions and research facilities can apply for institutional pricing.
- Satisfaction & Integrity Guarantee
If Something Is Wrong, We Make It Right.
If your order arrives damaged, compromised, or the COA doesn't match your vials, we will replace it at no cost. No complicated returns process. Email us with a photo, and we resolve it. We would rather lose a sale than send a researcher bad data.
Our team responds within 24 hours. For urgent research timelines, flag your order as time-sensitive in the order notes and we prioritise same-day dispatch.
What Happens Before Your Order Ships
Most peptide suppliers test a representative sample from the manufacturer. We test every batch independently — because manufacturer certificates are not independent verification.
- Intake & Quarantine
Raw material is received and held in quarantine at -20°C until testing is complete.
- HPLC-UV Analysis
High-Performance Liquid Chromatography confirms purity percentage vs. known reference standard.
- MS Identity Confirmation
Mass spectrometry verifies the molecular weight matches the expected compound exactly.
- Lyophilisation & Vial Sealing
Only passed batches are lyophilised, vial-filled under sterile conditions, and sealed.
- COA Issued & Shipped
Certificate of Analysis is generated, attached to your order, and shipped with temperature control.
The Rainbow Peptide Guarantee
If any order arrives damaged, degraded, or with a COA that doesn't match what you received — we replace it. No forms, no lengthy process. Email us a photo within 30 days of delivery and we make it right. Your research timeline is not our casualty.
