Go to a Gatherer’s garden and buy either all slots for your plasmids or all slots for the physical, engineering or combat tonic slots. I believe you start with 2 slots open for each so you need to buy 4 extra slots in whatever track you want. Once all 4 extra are bought for one track, the track will be maxed out and the trophy will pop. Plasmid slots cost 100 and the tonic slots are 80 a piece. I don’t believe you can buy them all at once early on in the game. I had roughly 600 Adam early on and could only buy 2 plasmid tracks and a Gatherer’s Garden. I maxed one of mine out at Farmer’s Market.
You will naturally get this trophy if you are also going for the
