Klow80
TB-500
Tirzepatide
Every compound.
Independently verified.
We refuse to compromise on purity. Before any compound reaches our catalog, it undergoes rigorous mass spectrometry and HPLC analysis at ISO 17025-accredited laboratories. Your research deserves nothing less.
Our quality process isn't a checkbox — it's a multi-stage protocol developed with input from analytical chemists. Every lot is traceable, every result is published, and every rejection is documented.
Third-Party Tested
ISO 17025-Accredited Labs
Every batch is dispatched to independent ISO 17025-accredited laboratories before listing. We never self-certify. Results are reviewed by our in-house biochemist before any product is approved for sale.
Certificate of Analysis
Full Transparency, Every Lot
A complete COA is published for every product lot — including identity confirmation, purity percentage, moisture content, and residual solvent levels. Accessible directly from each product page.
99%+ Purity Standard
Non-Negotiable Threshold
We only list compounds that consistently test above 98.5% purity across multiple independent runs. Any lot falling below this threshold is rejected outright — regardless of cost or availability.
Cold-Chain Shipping
Integrity From Lab to Door
Lyophilised peptides are temperature-sensitive. Every order is packed with pharmaceutical-grade cold packs and insulated liners, dispatched from our Australian facility within 48 hours of order confirmation.
Sequence Verification
Amino Acid Confirmation
Beyond purity, we verify the exact amino acid sequence of each peptide using LC-MS/MS analysis. This confirms you're receiving the correct compound — not just a high-purity unknown substance.
Stability Testing
Shelf-Life Validated
Each compound undergoes accelerated stability testing to confirm potency retention over time. Expiry dates are conservatively assigned based on real degradation data, not manufacturer estimates.
Synthesis & Receipt
Raw compound received from GMP-certified synthesis partner with preliminary documentation.
Independent Lab Dispatch
Sample sent blind to ISO 17025 lab — no brand information included to prevent bias.
Multi-Method Analysis
HPLC, mass spectrometry, and sequence verification run in parallel across 3 independent samples.
Internal Review
Our biochemist reviews raw data. Any anomaly triggers a full re-test from a new lot.
COA Publication
Approved lot COA published to product page. Lot number traceable from order confirmation.
Built for researchers
who won't compromise.
CompletePeptides was founded by researchers frustrated with inconsistent purity, opaque sourcing, and unreliable supply chains. We built the supplier we wished existed.
Unreliable gray market → Verified research-grade supply
Australia-Based Fulfillment
All inventory held in our Australian warehouse. Orders dispatch within 48 hours, no customs delays.
Transparent Sourcing
We publish our supplier list and batch origins. Know exactly where your research compounds come from.
Research Support
Access to our team of biochemists for dosing protocols and stacking questions. Email support within 4 hours.
Reorder Consistency
Same formulation, same supplier, same purity. Your protocols don't change because our supply chain doesn't.
Trusted by researchers
who demand precision.
“Fastest dispatch I've experienced. Arrived cold-packed and perfectly intact. Purity matched the COA exactly.”
“The Glow70 blend is exceptional. Published COA gave me full confidence before ordering.”
“Finally a supplier that publishes batch-level COAs. Reordered 4 times — same purity every time.”
“MT-2 from CompletePeptides is the benchmark. 99.6% on HPLC — nothing else comes close.”
“Support team answered my stacking questions within 2 hours. Rare level of service.”
