Hard to say what the plan is here, file Form 15, do a share exchange, go back private and then take TetraPharm public at a later date....??
INSD is not going to be revivable any time soon. PNPL was able to come back from suspension here recently, after a promo in 2016 got it suspended and a CE..... but it took 7 long years. At the current rate, the OTC may not even be around anymore in 7 years.
