From EU synthesis to your bench — every step, traceable.
Most research peptides change hands three or four times before they reach a researcher — and each handoff introduces a new point where the chain of custody can break. Vivaprime owns the path end-to-end, and publishes what happens at each step.
Synthesis
Every Vivaprime compound is manufactured in a licensed EU pharmaceutical facility operating under cGMP. Synthesis follows pre-registered specifications — identity, purity, amino-acid composition, residual-solvent profile — validated against reference material for each peptide. Batches are produced in discrete, tracked runs; nothing leaves the facility without a documented QA signature.
Release testing
Each batch is analysed by reverse-phase HPLC for identity and purity, with AAA / HPLC-MS confirmation of sequence. Residual solvents are measured against ICH Q3C limits (Class 1 / 2 / 3). Endotoxin is measured by LAL, reported in EU/mg. A Certificate of Analysis is issued per batch — reviewable before, during, and after purchase.
Fill & finish
Each pen is factory-filled against a calibrated concentration. The cartridge, plunger, and dose dial are assembled in the same facility, under the same QA protocol as the active ingredient. No reconstitution step downstream — what's inside when it seals is what arrives at your door.
Cold-chain export
Pens move to our US 3PL in validated, temperature-logged shipments. Every export shipment carries its own cold-chain record, independent of individual customer orders. Our US facility confirms the 2–8 °C band on receipt before stock is released to inventory.
US 3PL fulfillment
Your order is picked from US inventory, packed with phase-change cold packs calibrated for 72 hours of in-box stability, and handed to the carrier within 1 business day of payment. Transit windows are tuned — we don't ship on Fridays if weekend layover would risk the cold window.
Receipt & verification
Your Shipping confirmation email carries the tracking link and carrier. On arrival, every order page shows the batch COA for the exact pens you received. Anything out of spec — a warm package, a damaged seal, a cold pack that failed — gets replaced at our cost, no questions, within 24 hours of report.
Every batch publishes a COA
We don't hide lab results behind a gated PDF. Current-batch purity, identity, residual solvents, and test date are listed on every product page. See our testing methodology for what each number means.
How we test →Cold chain is enforced, not advertised
Phase-change packs + 72-hour insulation. Transit windows are tuned to stay inside the stability budget. Warm shipment = replacement at our cost.
Shipping details →Research-use only — clearly
Every SKU ships with a research-use agreement that you affirm at checkout. No therapeutic claims, no health claims, no ambiguous marketing — because the facts about these compounds speak for themselves.
Research-use policy →If the process isn't documented, it didn't happen.
Our whole business runs on the assumption that research buyers want to verify — not trust us on marketing copy. Every step above is recorded, and every batch is traceable back to its synthesis release. If you need the specific facility code or batch-level documentation for an institutional purchase, email us — we share it on request.
