Question: Is condensed milk the same as sweetened condensed milk? 

I have a fudge recipe that calls for condensed milk and I can not find strictly condensed milk, only sweetened condensed milk or evaporated milk.

Answer: 
In my experience, "condensed" milk refers to the sweetened product, and "evaporated" milk refers to the unsweetened product. People will often say "sweetened condensed" for clarity, but this is not strictly necessary: if your recipe calls for condensed milk, use the syrupy stuff.

However, if this is an older recipe, all bets are off: older casual usage had "condensed" for both meanings. (Hence using the "sweetened condensed" phrasing, even though it's a bit of a tautology.)
No, the two products are different. As the names imply:

* *Condensed milk* is strictly reduced milk
* *Sweetened condensed milk* is reduced milk with considerable sugar added

See [Can evaporated milk be converted to sweetened condensed?](https://cooking.stackexchange.com/questions/4600/can-evaporated-milk-be-converted-to-sweetened-condensed) You can easily modify the condensed milk with additional sugar.
