Price Tips
- Bigger vials = lower $/mg. A 60mg vial is almost always cheaper per milligram than a 10mg vial from the same vendor.
- Watch for bulk discounts. Many vendors offer 10-20% off when buying 3+ vials.
- COA matters. The lowest-priced vendor without third-party testing isn't actually a deal — it's a gamble.
- Factor in shipping. Some vendors offer free shipping over a threshold that changes the math.
