How do I get a Strength and Time Potion if I'm lvl 100?

[PlayingHazard]

I just bought the game and hit lvl 100, so I decided to go back to the starting area to do the Golden Egg Quest. Now I've found out I can't do it because I can't grind Gold Boxes for Strength and Time Potions, so is there a way to get any?

(I don't want to prestige and I've already collected the Time and Strength Potions that were free in chests in the early game and used them because I didn't know what they did.)

There is a hidden path in the trees to the south of the community college in area 2 to collect a time potion. The strength potion I you should be able to get all three keys and buy a strength potion inside the wardrobe from the syatar without any other potions

you can also go to the ama-zone warehouse in diamond city, the top door, not the one you work at, you can infinitely buy boxes of either type.
