The Doc Johnson Great American Challenge is one of the biggest realistic dildos we stock, a genuine test piece for anyone chasing extreme size. Sculpted from soft jelly rubber with a lifelike shape, this dong is designed for experienced users who want to push their limits.
Why people choose this dildo
This toy has a reputation for a reason. The scale alone makes it a talking point, and the soft, flexible jelly rubber gives it enough give to work with rather than against you. It is a popular choice for collectors, size enthusiasts and anyone looking for a genuine challenge rather than a novelty gift.
Material and safety
This dildo is made from soft jelly rubber (PVC). Jelly rubber materials are porous, so we recommend using a condom over the toy for hygiene, since porous materials cannot be fully sterilised between uses in the way that silicone can. Always use a water based lubricant with this toy and clean it thoroughly with warm water and a mild toy cleaner after every use.
Size and fit
This is an extreme size toy, so please only choose it if you are confident you can work up to it safely and with plenty of preparation.

- Diameter: 2.7 inches (6.8 cm)

Getting started
- Place a condom over the toy for hygiene, since jelly rubber is a porous material.
- Apply a generous amount of water based lubricant to the toy and to yourself.
- Warm up thoroughly and build up gradually. Do not attempt full insertion straight away given the size of this toy.
- Remove and dispose of the condom after use, then wash the toy with warm water and a mild toy cleaner. Allow it to air dry fully before storing.
Storage
Store the toy somewhere clean, cool and dry, away from direct sunlight, ideally in a fabric storage bag or box. Keep jelly rubber toys separate from silicone toys in storage, as different materials can react with one another on contact over time.
Delivery
Every order ships in plain, unbranded packaging with fast UK delivery, so nothing on the outside of the parcel gives away what is inside.
