# Anvil — Naturally optimize your testosterone

Anvil tracks the daily habits that shape your hormones, scans what you eat, and turns optional bloodwork into a personalized testosterone estimate — all grounded in published research.

Every score and recommendation is backed by published research — no bro-science.

## A testosterone estimate that evolves with your habits

Anvil estimates your testosterone as a range that updates as you log — never a single hard number. Upload a morning blood draw to calibrate the estimate to your personal level.

## Scan your food, products, and body

Point your camera at a meal, label, or barcode to flag seed oils and harmful ingredients with an instant health score. A body scan estimates your body-fat range and feeds your Daily Score.

## How Anvil estimates your testosterone

1. **Your natural ceiling** — genetics and physiology set the range your body can reach.
2. **Your daily habits** — the part you control, the lifestyle factors Anvil scores every day.
3. **Your bloodwork** — optional lab draws calibrate the estimate to your personal level.

## Disclaimer

Anvil's Daily Score is based on modifiable lifestyle factors and published research; a score of about 65 is roughly average. Anvil is a lifestyle optimization tool, not a medical device, and does not diagnose, treat, or prevent any condition. Always consult a healthcare provider.
