It's a good combo of compounds, but for offseason run the tren and superdrol low. probably 400 or less tren, ideally more like 250 or so, and then no more than 10mg superdrol. 20+mg is for peaking for a bbing show or a pling meet, running that much will be couterproductive to muscle building as you can't eat.
Maybe something like 1g test, 300 tren e, 10mg superdrol sublingual pre-workout only, then a shit ton of gh and insulin based on carb intake you need to grow.
