For this you need to craft four different things, which you gradually unlock in the "Shadows of Rose"-DLC.
There are four crafting materials:
Herbs - Chem Fluid - Gunpowder - Rusted Scrap
Out of these you can craft four different things needed for the trophy:
First Aid Med (Herbs + Chem Fluid)
Handgun Ammo (Gunpowder + Chem Fluid)
Shotgun Ammo (Gunpowder + Rusted Scrap)
Pipe Bomb (Rusted Scrap + Gunpowder + Herb)
You will be able to get the trophy after you collect the Silver Mask (the second of the three), and once you find your first piece of Rusted Scrap you can craft Shotgun Ammo, then reload and craft a Pipe Bomb and you will still immediately unlock the trophy, no need to craft everything at the same time in one continuous run. There ya go!
