What is Trust Score?
A transparent 0-100 safety rating that helps you choose reliable peptide suppliers. No more guessing which Reddit recommendations you can trust.
The Problem: Fake Reviews Everywhere
If you've tried researching peptide suppliers on Reddit or forums, you've seen:
Fake accounts promoting specific vendors
Brand new accounts with glowing reviews
Competitors posting fake negative reviews
Vote brigading and coordinated attacks
Outdated information
Year-old threads about vendors who've changed completely
No objective data
Just opinions - no lab testing verification
The Result?
You waste hours researching and still have no idea who to trust. Trust Score solves this.
How Trust Score Works
Trust Score combines objective lab testing data with verified customer reviews in a 60/40 split.
60% Objective Facts
Things vendors can't fake:
- Lab Testing: Recent COAs from Janoshik/MZ Biolabs showing >98% purity
- Shipping: Delivery success rate, tracking, packaging quality
- Payment: Secure checkout, clear refund policies
40% Real Customers
But only VERIFIED reviews:
- Post-purchase only: Must provide order confirmation
- Email verified: No fake accounts allowed
- Anti-spam: Rate limiting, manual fraud review
Why 60/40?
The 60% objective weight protects vendors from fake review attacks. Even if competitors leave 50 fake 1-star reviews, the score can't drop below 60% of the lab testing + shipping score. But customer service still matters - vendors with poor reviews will see their score drop over time.
How to Use Trust Scores When Shopping
Search for your peptide (e.g., "Retatrutide")
Use the search bar or browse compounds. You'll see all available suppliers sorted by Trust Score (highest first).
Check the Trust Score tier
Compare price vs. trust
The cheapest option isn't always the best. A 95-rated vendor at £75 might be better than a 65-rated vendor at £60.
Pro tip: Look for the "LAB" badge (lab tested) and check the price per mg to compare value across different vial sizes.

What Makes a High Trust Score?
Recent Third-Party Lab Testing
COAs (Certificates of Analysis) from Janoshik or MZ Biolabs dated within the last 3 months, showing >98% purity and LC-MS/MS identity confirmation.
Reliable Shipping
95%+ successful delivery rate, tracking numbers provided, ships within 24-48 hours, discreet packaging.
Secure Payment
SSL/HTTPS checkout, multiple payment options (cards, crypto), clear refund policy, PCI compliance.
Positive Verified Reviews
4.0+ star average from customers who've actually purchased and received their orders.
Red Flags to Watch For
No Lab Testing or Old COAs
If COAs are missing or over 6 months old, purity can't be verified. Avoid or ask vendor for updated testing.
Trust Score Below 70
Indicates issues with lab testing, shipping problems, or poor customer reviews. Proceed with caution.
Shipping Complaints in Reviews
Multiple verified reviews mentioning lost packages, long delays (>7 days), or damaged products.
Sudden Score Drops
If a vendor's score dropped 10+ points recently, check their reviews to see what changed.
Common Questions
Should I only buy from 90+ rated vendors?
Not necessarily. 80-89 vendors are still very reliable. Sometimes newer vendors with excellent lab testing haven't accumulated many reviews yet. Check the breakdown to see why the score is what it is.
Can vendors manipulate their Trust Score?
The 60% objective weight (lab testing + shipping + payment) can't be faked. Reviews require post-purchase verification and email confirmation. We have anti-spam filters and manual fraud review. It's far more secure than Reddit upvotes.
What does the "LAB" badge mean?
Vendors with the green "LAB" badge have recent third-party lab testing (COAs) from Janoshik or MZ Biolabs showing >98% purity. This is the gold standard for peptide verification.
Is the cheapest price always the best deal?
No. A vendor selling "Retatrutide" at £40 with no lab testing might actually be selling degraded or fake product. A 95-rated vendor at £75 with recent Janoshik COAs is better value - you're paying for verified quality.
How often do Trust Scores update?
Real-time. Every verified review recalculates the score immediately. Lab testing scores update when vendors submit new COAs. Price comparisons refresh every 6 hours.
Can I leave a review?
Yes! After purchasing from any vendor listed on SaveOnTheVial, you can leave a verified review. We'll ask for your order confirmation or tracking number to prevent fake reviews.
