Joint distribution of gammas

I'm trying to find the joint distribution of two independent identical gammas, say X~gamma(a,b) and Y~gamma(a,b).
Is there any quick way to find it? Since they're independent? I know the joint will be the product of the marginals. Will the marginals just be the pdf of X and Y?
If I'm not being clear, im asking if I can just multiply two gammas?

$\text{independence} \Rightarrow \text{joint distribution is the product of the marginals}$

so yes, just multiply the two gamma distributions
