  Nuggets---very large stable bound objects arising in the presence of a
sufficiently attractive and long-range force and in the absence of a dark
Coulomb force---are a smoking gun signature for Asymmetric Dark Matter (ADM).
The cosmology of ADM nuggets is both generic and unique: nuggets feature highly
exothermic fusion processes, which can impact the shape of the core in
galaxies, as well as give rise to rare dark star formation. We find,
considering the properties of nuggets in a generic extended nuclear model with
both attractive and repulsive forces, that self-interaction constraints place
an upper bound on nugget masses at the freeze-out of synthesis in the ballpark
of $M_{\rm fo} \lesssim 10^{16}$ GeV. We also show that indirect detection
strongly constrains models where the scalar mediator binding the nuggets mixes
with the Higgs.
