How We Rate

Each service gets a score out of 10 built from five weighted factors:

1. Formula (30%): what is actually in the medication, and whether it addresses more than one cause.
2. Speed and duration (20%): how fast it can start working and how long the window lasts.
3. Delivery method (15%): swallowed pill, chewable or under-the-tongue, and how food affects it.
4. Medical process (20%): US-licensed providers, a real medical intake and US pharmacies.
5. Value (15%): price per day, renewal terms and when you are charged.

Vigo MD currently scores 9.4/10, our highest rating, mainly for its two-part, four-ingredient formula and under-the-tongue delivery.
