From past experience .. you will gain water weight it could do both man depends on what You wanna do personally for me
BULK Size n Strength: MK677 25mg day / LGD 10mg 8 weeks -Lift Heavy
CUT: MK677 25mg day / LGD 5mg 8 weeks / Cardarine 10-15mg day
......LGD is suppressive and you will want to run. A good PCT, if it was me, I’d run like at least clomid 40/40/20/20 and some decent test booster like d-aspartic acid but your on TRT so in reality who cares
