We use a molten flux growth technique to precipitate pristine LaAlGe single crystals that crystalize in the non-centrosymmetric crystal structure required for Weyl points to exist. We will discuss our electrical transport, magnetization, penetration depth, and heat capacity measurements of this topological compound, detailing both our experimental results and the future implications of this work.
