What People Notice After Comparing
"The cheapest option wasn’t actually cheaper. Once I added shipping, the 'premium' vendor won."
"Shipping doubled my cost on small orders. I didn't realize until I saw it side-by-side."
"I stopped guessing where the money went. It’s just math now."
Common Questions
Does this compare quality or recommend vendors?
No. This tool compares order totals (math only), not compound quality or supplier reputation. Always verify COAs independently.
Why do I see different totals at checkout?
Shipping thresholds and processing fees often change the final price significantly. This tool normalizes those hidden costs so you see the real total.
Can I save my vendor profiles?
Pro users can save vendor profiles to benchmark prices over time and track market trends.
How is 'Price per Mg' calculated?
We take the total effective cost (including shipping/fees) and divide it by the total milligrams in your cart. This balances different vial sizes.
