Workout, supplement, diet combo question

[Firefox]

So this summer I have to go Home and work on the beach as a lifeguard. I'll have no gym membership because Im not going to pay 400 for a summer account. There's a cheaper gym for 10 a month but they have only cardio equipment and DBs up to sixty, no free benches what so ever and only smith machines.

Here's my plan.
-I was going to follow the P90x program because thats something i can do in the guard room or at home.
- I'm going to due the p90 diet strictly (comes to about 1600 call a day!!low) and high in protein and low in carbs

My supplement questions are:
1. Are these multivitamins pills BS, like is it just expensive urine or is it absorbed into the body?

**2. I want to run a Clen + T3 combo. I've taken clen before and fat just melts off, but with a high cardio work out and low cals would it be a good idea to run those together. And are there enough cals in a diet that low to even take T3?**

I have heard good things about P90x but 1600 calories without taking into account your size and activity level sounds like b.s. You might revaluate that.
Check out the diet section and they can help you more. I am not a guru.
Leave the t3 alone unless you are using gear, imho. Clen is great with a proper diet and cardio, But again, at 1600 cal. you may not need any help. Sh!t you may not have enough energy to take it. Multi vitamin is important with any training. I prefer mega men sport. Take them with a meal.
