Stop pinning until you have everything you need or think you will need. You will be fine from one weeks worth of 500 mgs of ugl gear. Don't be so impulsive next time. Taking Nolva will prevent you from developing gynocomastia. But your E2 levels would still likely be elevated and you could still have all other sides of elevated E2 levels possibly.
Honestly just don't even touch the stuff. Just eat clean and train appropriately. You aint really bout dat life.
