Best Places to Buy GLP-3 Online in 2026
We ordered from a dozen online vendors and evaluated each on independent lab testing, shipping speed, pricing, and customer support. These three came out on top.
Amino Club
The most consistent vendor we tested. Every batch ships with a matched third-party certificate of analysis, and both of our test orders arrived in under three days with tracking.
- Batch-matched third-party lab reports
- Fastest shipping in our tests (2–3 days)
- Responsive support (under 4 hrs)
- Slightly higher base pricing
- Popular items sell out quickly
Ascension
Runs steep sales — R-10 (10mg) is currently $99 down from a $149.99 list price — with volume pricing on 3, 5, and 10-vial orders and free shipping over $250, making it a strong pick for larger orders.
- Volume pricing on 3, 5, and 10-vial orders
- Free shipping over $250
- Publishes lab results publicly
- Standard shipping runs 4–6 days
- Support limited to email
Mile High Compounds
A smaller operation with the best customer service we encountered — live chat, a generous reship policy, and clear answers to product questions. Selection is narrower than the other two.
- Live chat with real answers
- No-questions reship policy
- Discreet, well-packed orders
- Smaller product selection
- Lab reports on request only
