Not exactly. You might be interested in this article, entitled Metousiosis (emphasis mine).
b. Orthodox profess a real change (metabole) of the bread and the wine into the body and blood of Christ by the Words of Institution and the act of the Holy Spirit in the eucharistic anaphora. This does not mean a “transsubstantiation” of the substance of the bread and the wine into the substance of the deified humanity of Christ, but a union with it: “The bread of communion isn’t an ordinary bread, but united with divinity” (John of Damascus). This union amounts to a communication of the deifying properties of the humanity of Christ and of the deifying grace of his divinity to the eucharistic gifts: The bread and the wine are no longer understood with respect to their natural properties but with respect to Christ’s deified human body in which they have been assumed through the action of the Holy Spirit. As in Christology the two natures are united hypostatically, so in the Eucharist Christ’s exalted human body and the “antitypes” (St. Basil, Anaphora) of bread and wine are united sacramentally through the act of the Holy Spirit.
Bolding is minec. Orthodox and Lutherans agree, whether they use the language of “metabole” or of “real presence”, that the bread and wine do not lose their essence (physis) when becoming sacramentally Christ’s body and blood. The medieval doctrine of transsubstantiation is rejected by both Orthodox and Lutherans.

Erich,
Perhaps we should wait for someone who is Orthodox to clarify.
