hydrolyze tren acetate with a 1M solution of NaOH (or Na2CO3) in ethylalcohol/water, filter and you have base
put the base in chloroform with DMAP, heptanoyl chloride and some pyridine, stir for 4 hours, shake with water + strong acid, water + weak base and brine, separate the chloroform fraction, evaporate, recrystallize, and voila. Yes, this can be done at home
