How We Ranked These Vendors

Every vendor on this list was evaluated across four weighted criteria. We placed real orders, requested certificates of analysis, and timed shipping to three U.S. regions.

Independent lab testing — 40%
Publicly posted certificates of analysis from a third-party lab, matched to batch numbers.

Pricing & value — 25%
Cost per order after shipping, with bulk and subscription discounts factored in.

Shipping & handling — 20%
Delivery time, cold-chain packaging where applicable, and tracking reliability.

Customer support — 15%
Response time to email inquiries and clarity of return and reship policies.

Frequently Asked Questions

What should I look for before ordering?
Batch-matched certificates of analysis from an independent lab, a physical business address, and a clear reship or refund policy. All three vendors above meet that bar.

How fast is shipping?
Our test orders arrived in 2–6 business days within the U.S. Expedited options are available from all three vendors.

Do these vendors offer discounts?
Yes — all three run first-order codes and bulk pricing. Check each site’s current offer via the buttons above.
