No, it is a neurotransmitter. A hormone, is a compound produced by an endocrine gland and released into the bloodstream. A neurotransmitters are chemicals that transmit signals from a neuron to a target cell across the synapse and most are synthesized at the nerve terminals.
Synaptic vesicles in the neuromuscular junction contain acetylcholine (ACh) which is the neurotransmitter for initiating muscular contractions.

Acetylcholine is the neurotransmitter at the neuromuscular junction.

Acetylcholine is the excitatory neurotransmitter released by neurons innervating skeletal muscles. Acetylcholine release stimulates muscle contraction by acting at the nicotinic-acetylcholine receptor on the surface of the muscle cell.
nicotinic acetylcholine receptors (nAChR, also known as "ionotropic" acetylcholine receptors) are particularly responsive to nicotinemuscarinic acetylcholine receptors (mAChR, also known as "metabotropic" acetylcholine receptors) are particularly responsive to muscarine.Nicotinic and muscarinic are two main kinds of "cholinergic" receptors.
