Probably Stolen Reducing Agent: Where to Get It
Where to find Reducing Agent in Probably Stolen: the restricted supply pack, the Retired Chemist unlock, and its role in Nomore and Phanta.
Reducing Agent comes from Chemical Supplies (Restricted), not from the common chemical pack. One restricted pack contains one 250 mL bottle of Reducing Agent and two bottles of N-Methylol Base. If you are buying common packs and hoping for a Reducing Agent, you are buying the wrong package.
The ingredient is used in two advanced production chains: Nomore injectors and Phanta pills. It is an electron-donating reagent, not a universal purifier. Adding it to a dirty mixture will not remove heavy metals or fix a bad temperature.
Buy Chemical Supplies (Restricted), unlock chemistry trading through the Retired Chemist, and keep the Reducing Agent separate from the N-Methylol Base. Use it in Nomore at 45–55°C or Phanta at 110–129°C — not as a cleaning agent.
Where Reducing Agent comes from
There are two chemical supply packages in the game:
| Package | Contents | Listed pack value |
|---|---|---|
| Chemical Supplies (Common) | Alcohol, Lipobond Agent, Acidic Solution, Basic Solution | 50 credits |
| Chemical Supplies (Restricted) | Two N-Methylol Base bottles, one Reducing Agent bottle | 100 credits |
The individual Reducing Agent bottle has a listed value of 3 credits and occupies a 1 × 2 inventory space. That bottle value is not the cost of the pack. The pack is the acquisition route; the bottle is the ingredient.
The 250 mL figure is the volume of the full bottle. It is not a dosage instruction. The amount consumed depends on the recipe and on what is already in the receiving container.
The unlock you need first
Chemicals are not tradeable until you own the Retired Chemist upgrade, or until you start with the Chemist background. The Retired Chemist visits on Tuesdays and brings chemistry machines, supplies, glassware and modules.
That creates two separate checks:
- Do you have chemistry trade unlocked? If not, the supplier will not appear with stock.
- Are you buying the Restricted pack? If not, the pack will not contain Reducing Agent.
Players who started as a Chemist should inspect their starting supplies before buying duplicates. Players who unlocked chemistry later should plan around the Tuesday visit rather than assuming the vendor is bugged.
Unpacking and separating the bottles
Use the restricted supply pack from your inventory. The contents become separate items. Keep the Reducing Agent bottle distinguishable from the two N-Methylol Base bottles; similar containers do not mean similar contents.
A clean preparation sequence:
- Confirm the package says Chemical Supplies (Restricted).
- Unpack it.
- Move the Reducing Agent bottle to a dedicated storage slot.
- Keep the two N-Methylol Base bottles separate.
- Reserve the amount your recipe needs.
- Inspect the receiving container with the Composition Spectrometer before adding anything else.
The spectrometer is the difference between a supply problem and a mixture problem. If a batch fails, check what is actually in the container before buying another bottle.
What Reducing Agent is used for
Nomore
Nomore uses Dream Cap Extract, Reducing Agent and Lipobond Agent. The reaction runs at 45–55°C while alcohol is at most 10%. Having the Reducing Agent is only one prerequisite; the extract, the Lipobond Agent and the temperature all matter.
Phanta
Phanta requires N-Methylol Base in excess of the Stabilizing Agent, with Reducing Agent as part of the reaction at 110–129°C. Phanta decomposes at 130°C, so do not chase the top of the range. A plate that fluctuates by ten degrees can ruin the batch.
Phanta yields only 0.5 mL per vial, so losses are expensive. The chemistry recipes→ page lists the full inputs, temperatures and yields. The chemical supplies→ page explains how to source the other restricted precursors.
What Reducing Agent does not do
It does not remove heavy metals. Heavy metals are the contamination class that ordinary filters and tablets cannot fix; a proper purifier or a different production route is the answer. Reducing Agent also does not replace the Blender, Heating Plate, Evaporator or Chem Finisher.
The chemistry chain is:
- Blend the reagents.
- Heat to the recipe's temperature.
- Extract the active product.
- Finish it into a saleable form.
Reducing Agent belongs to the mixture stage. If the batch is contaminated, the problem could be the input, the machine, the modules or the container. The chemistry guide→ covers machine purity and module math.
Common mistakes
| Mistake | Result | Fix |
|---|---|---|
| Buying Common supplies repeatedly | No Reducing Agent | Buy the Restricted pack |
| Using Reducing Agent as a purifier | Contamination remains | Use the correct purifier or discard the batch |
| Mixing the whole bottle into a small batch | Wrong concentration | Measure to the recipe, not the bottle size |
| Heating Phanta to 130°C or above | Product decomposes | Stay at 110–129°C |
| Using Nomore temperatures for Phanta | Failed batch | Nomore is 45–55°C; Phanta is 110–129°C |
| Assuming a similar bottle is the same chemical | Wrong reagent | Read the label and inspect with the spectrometer |
The first two are the most expensive. The pack type is a hard gate, and Reducing Agent is not a cleaning chemical.
Is the restricted pack worth it?
The pack costs 100 credits and gives one Reducing Agent plus two N-Methylol Base bottles. If you are producing Nomore or Phanta, that is the normal input cost. If you are not, the pack is dead inventory.
A practical rule: buy the pack when you already have the other recipe ingredients and a customer or display slot for the finished product. Do not buy it speculatively because the vendor happens to be in town. The money guide→ covers margin planning for chemistry products.
FAQ
Where do I buy Reducing Agent? From Chemical Supplies (Restricted), sold through chemistry trading. The common pack does not contain it.
How much Reducing Agent is in a pack? One 250 mL bottle, plus two N-Methylol Base bottles. The bottle's listed value is 3 credits.
Do I need the Retired Chemist? Yes, unless you started as the Chemist. The Retired Chemist unlocks chemistry trading and visits on Tuesdays.
What is Reducing Agent used for? Nomore and Phanta, plus other reactions that call for an electron-donating reagent. It is not a general purifier.
Can I use it to remove heavy metals? No. Heavy metals require the appropriate purification method, not Reducing Agent.
Why did my Phanta batch fail? Check the N-Methylol to Stabilizing Agent ratio, the 110–129°C window and the container. At 130°C the product decomposes.
Can I buy just the bottle? The normal route is the restricted pack. The bottle is an unpacked ingredient, not a separate vendor listing.
