After discovering I could buy retatrutide directly from China for a fraction of the US supplier cost, the obvious question became: is it actually legitimate? Enter Finnrick a service offering free third-party testing that could answer this question definitively. Here's exactly how the process works and what happened when I sent my sample. ## Discovering Free Testing While researching sourcing options, I stumbled across [Finnrick.com](https://www.finnrick.com/) and their [free sample testing program](https://www.finnrick.com/free-sample-test?i=hd). This was exactly what I needed to validate my Chinese supplier purchase. **What they offer:** - Free testing of research peptides - Commercial lab analysis - Certificate of analysis before public posting - No cost, just ship them a sample ![Screenshot from 2025-07-28 17-22-53-fotor-20250728172355.png](https://retatrutidelog.com/uploads/28b14c7c-756d-47f2-954e-fe12dc8a26c7.png) The process looked straightforward, but I wanted to document every step since this could be valuable for others in the same situation. ## The Application Process **Step 1: Account Setup** I created an account using my Gmail simple and quick registration. **Step 2: Sample Details** The form asks for specific information: - Product type (Retatrutide selected) - Quantity in mg (as indicated on vial) - Optional batch ID information - Whether vendor supplied Certificate of Analysis **Important note:** They make it very clear that samples are destroyed during testing. You won't get your vial back. ## Timeline: From Submission to Sample Receipt Here's exactly how the process unfolded: ### Saturday, July 19th - Initial Submission - Submitted sample testing request through Finnrick website - Received **Test Request Confirmation** email same day - Process officially started ### Monday, July 21st - Shipping Instructions - Received email with **shipping instructions and testing ID** - Got specific address and packaging requirements - Clear guidelines on how to label and ship ### Tuesday, July 22nd - Sample Shipped - Packaged sample according to instructions - Shipped with tracking number - Provided tracking information to Finnrick team ### Wednesday, July 23rd - Vendor Information Request - Representative asked for additional vendor information - Requested links and supplier details - Provided requested information same day ### Monday, July 28th - Communication Mix-up - Rep asked if I had received shipping instructions (already shipped days ago) - Sent screenshot of tracking showing **delivered July 24th** - Included testing ID and shipping confirmation for clarity ### Monday, July 28th (Later) - Sample Confirmed Received - Received email: **"We Received Your Samples"** - Estimated timeline: **Results within 2 weeks** - Promise: Results by email before website publication ![Screenshot from 2025-07-28 17-21-36.png](https://retatrutidelog.com/uploads/de2e8a1c-65d0-42ad-891a-2e844cf03475.png) ## What Gets Tested Finnrick accepts most common research peptides in lyophilized powder form, including: - Retatrutide ✓ - Semaglutide ✓ - Tirzepatide ✓ - GHK-Cu ✓ - BPC-157 ✓ - And many others **What they DON'T accept:** - Tablets or capsules - Sprays, liquids, or gels - Reconstituted peptides - Shipments from outside USA ## The Value Proposition **For me:** Validates whether my $186 Chinese order is legitimate quality **For the community:** Creates public data on supplier quality **For Finnrick:** Builds database of peptide quality across suppliers This is essentially crowd-sourced quality control for the research peptide community. ## What I'm Testing **Sample details:** - Product: Retatrutide 15mg vial - Source: Chinese supplier (direct order) - Cost: Part of $186 order (10 vials total) - Batch: From July delivery **What the results will show:** - Actual peptide content and purity - Presence of contaminants - Whether the labeling is accurate - How it compares to other tested samples ## The Waiting Game Begins Now comes the hardest part: waiting up to two weeks for results. This will definitively answer whether my cost-saving sourcing strategy actually delivers quality product. **What's at stake:** - Validation of direct Chinese sourcing - Confidence for future orders - Data for the community - Proof of concept for the testing process ## Why This Matters If the results show high purity and accurate labeling, it validates the direct sourcing approach and could save people significant money. If the results show problems, it's a valuable lesson about the risks of cutting costs. Either way, having real data is better than guessing. **Part 2 coming soon:** The actual test results and what they mean for peptide sourcing.
