Probably Stolen Immunivax Guide: How to Get, Authenticate, and Survive

Learn how to find and authenticate Probably Stolen Immunivax doses, survive SCD runs, hide medical loot from security, and manage your shop economy.

Surviving the gritty slums of a cyberpunk station takes more than just trading scrap and haggling over filtered water. If you are playing through intense challenge modifiers like Sentinel Collapse Disorder (SCD), finding a genuine dose of Probably Stolen Immunivax is literally the difference between life and death. Without regular doses, your health deteriorates day by day until your pawnshop empire crumbles into an early grave. Understanding how to acquire and protect Probably Stolen Immunivax will save your runs when the daily rent timer threatens to shut down your storefront for good.

In Probably Stolen, developers Questing Goose Studio have blended the tension of authentication mechanics with harsh resource management. This complete item breakdown covers everything you need to know about tracking down Immunivax vials, verifying medical serial codes, avoiding counterfeit traps, and hiding valuable pharmaceuticals from station security.

What Is Immunivax and Why Do You Need It?

In the dystopian setting of Probably Stolen, life on the lower deck carries severe health liabilities. When running specific difficulty modifiers—most notably Sentinel Collapse Disorder (SCD)—the protagonist suffers from a degenerative condition.

Every few days without treatment, the player takes persistent, unpreventable damage during the nightly phase. Left unchecked, your 20 maximum health points steadily chip away until you collapse. An injection of Immunivax stabilizes your biological vitals, extending your life span by roughly nine days per dose.

Because this medication is scarce, highly regulated, and heavily restricted by upper-level authorities, it rarely appears in ordinary commercial shipments. Shopkeepers often have to purchase black-market supplies, open stolen locked containers, or negotiate with underworld smugglers.

Immunivax Metric	Value / Impact	Strategic Note
Primary Effect	Prevents SCD damage ticks	Grants ~9 days of biological stability per dose
Typical Vendor Cost	~150 to 300 Credits	Varies by vendor type and barter success
Manufacturer Label	Karmic Heal Pharmaceuticals	Must match official authentication logs
Authenticity Risk	High (Counterfeits exist)	Requires checking batch/lot serial numbers
Legality	Regulated / Often Contraband	Subject to seizure if scanned without a Smuggler's Bay

How to Find and Acquire Immunivax

Securing regular vials of this life-saving drug requires careful preparation and shop specialization. While players can build wealth through other trades, surviving SCD runs demands active manipulation of vendor spawn chances.

Primary Vendor Encounters

There are two primary everyday customer types that can bring you a syringe:

Medical Sellers / Upper-Level Pharmacists: These specialized merchants occasionally drop down to the lower wards to offload excess supplies under the table. According to community reports and player testing, setting up medical signage significantly boosts the baseline chance for medical traders to stop by your counter.
Thieves and Black Market Fences: When running underworld equipment (such as a Black Lamp), your chance of attracting shady thieves rises to around 13% to 15% per day. Thieves carry randomized goods, but they frequently possess stolen pharmaceuticals or locked industrial cargo.

Unlocking Medical Crates with Decryptors

Often, a thief or wandering scavenger like Giorgio won't carry loose doses; instead, they will sell you locked cargo containers labeled as Medical Boxes or Security Crates.

To open these, you must invest in high-tech shop apparatus from Dr. Jackson:

Cryptographic Desequencer: An electronic workbench tool used to decode corporate encryption cards.
Service & Medical Keycards: Blank chips or specific credentials tuned to the security level of the crate.

Unlocking these containers carries a high upfront credit investment, but player experience confirms that unopened medical crates have an exceptionally high probability of yielding an emergency dose.

Sourcing Method	Reliability	Daily Spawn / Success Rate	Primary Danger
Upper-Level Pharmacist	Very High	Low base spawn without medical signs	High cash cost (~180–250 credits)
Thieves (Black Lamp active)	Moderate	~13%–14% spawn; moderate item pool roll	Often labeled as stolen property
Locked Medical Boxes	High (inside loot)	Dependent on cargo crate sellers	Requires decryption cards & key chips
Dr. Jackson's Catalog	Low	Rotational daily stock	Expensive upgrade requirements

Appraisal and Counterfeit Detection

Blindly injecting pharmaceuticals in Probably Stolen will end your run faster than skipping rent. Counterfeiting is a core game mechanic: rogue peddlers frequently fill empty syringes with tainted solutions, relabel industrial solvents, or clone serial tags.

Before you finalize a transaction for Probably Stolen Immunivax, you must inspect the item using your authentication tools.

Step-by-Step Authentication Checklist

Brand Verification: Check the embossed logo. Official batches are branded under Karmic Heal Pharmaceuticals. Any misspelling or blurred lettering is an instant red flag.
Serial Number Matching: Inspect the numeric batch sequence against your station lookup ledger. Common verified batch stamps documented by the player community include sequences like #419 and #196.
Fluid Clarity and Color: Put the syringe against the appraisal light. Cloudy base water or tinted rust discoloration indicates an adulterated product.
Vendor Demeanor: Shady characters muttering about looking the other way almost certainly carry stolen goods. Stolen items can still be genuine medical-grade doses, but you run the risk of heat and security raids.

Syringe Attribute	Genuine Immunivax	Counterfeit Syringe
Manufacturer	Karmic Heal Pharmaceuticals	Generic, blank, or misspelled labels
Fluid Color	Crystal clear, viscous sheen	Cloudy, yellowed, or watery consistency
Ledger Registration	Matches active station lot records	Unlisted or revoked license code
Health Restoration	Halts SCD damage for ~9 days	Causes poison/toxic shock damage
Resale Potential	High demand among sick citizens	Causes extreme reputation loss if sold

Inventory Management and Hiding Stolen Meds

Once you purchase a genuine dose, managing your inventory grid becomes the next urgent puzzle. Security forces routinely sweep lower-deck shops for unregistered corporate assets. If an inspection team finds contraband sitting openly on your shelf, they will confiscate the drug, slap you with heavy fines, or haul your character off to the brig.

The Smuggler's Bay Strategy

The most reliable way to safeguard your pharmaceuticals is to purchase a Smuggler's Bay module from Dr. Jackson's nightly shop:

Concealment: Stashing your medication inside the Smuggler's Bay protects it from random room sweeps by lazy or corrupt patrol officers.
Space Management: Storage boxes occupy precious room on your inventory grid (e.g., standard security boxes can take up a 6x4 layout). Prioritize opening or storing vials rather than hoarding full-size crates on your sales counter.
Emergency Consumption: If security initiates a raid and you don't possess a concealed compartment, community strategies recommend injecting the medication immediately on the spot. While doing this before your previous dosage expires reduces total day-efficiency, preserving the life-saving buff is far superior to letting an inspector confiscate it.

Storage Solution	Capacity / Grid Footprint	Raid Detection Risk	Best Suited For
Open Counter Display	Any inventory slot	100% Confiscation on scan	Standard goods only
Trash Bin Temporary Stash	Small floor footprint	Moderate (Lazy guards miss it)	Emergency stopgap before nightfall
Smuggler's Bay	Compact modular compartment	Lowest (Shielded from scanners)	High-value meds & stolen boxes
Satchel Upgrade	Personal inventory expansion	Guard inspects if searched	Mobility and supply carrying

Long-Term Economy: Balancing Rent and Medication

Acquiring a vial is only half the battle; financing your medicine while keeping your landlord satisfied is the rest of the challenge. Rent increases on a relentless schedule regardless of how your sales went. If you spend every credit on Probably Stolen Immunivax, you risk defaulting on your store lease.

Maximizing Cash Flow for Medical Runs

Water Purification: Combine cheap rust-water lots with micro-filters to produce 99%+ pure drinking water. Water buyers are regular daily visitors and provide predictable baseline profits.
Battery Recharging & Modules: Keep your shop equipment powered with recycled batteries to ensure your moisture extractors and appraisal terminals never power down during rush hours.
Reputation Synergies: Raising your standing with underworld factions increases thief frequency, providing more opportunities to buy discounted supplies. Just be cautious of corporate reputation hits that might trigger aggressive audits.

Weekly Financial Milestone	Target Credit Reserve	Primary Expense Focus
Week 1 (Days 1–7)	150 – 250 Credits	Base rent, water filtration tools, first testing kit
Week 2 (Days 8–14)	300 – 450 Credits	Rising rent, Black Lamp purchase, emergency meds fund
Week 3 (Days 15–21)	500 – 750 Credits	Smuggler's Bay, Decryptor cards, second Immunivax dose
Week 4+ (Day 22 Onward)	1,000+ Credits	Store buyout fund, bulk pharmaceutical stockpiling

Frequently Asked Questions (FAQ)

How often do I need to take Immunivax in Probably Stolen?

Under the Sentinel Collapse Disorder (SCD) modifier, an injection of genuine Immunivax stabilizes your vitals for roughly nine days. You should aim to track down and secure a replacement dose around day six or seven to avoid taking nighttime biological damage.

Can a thief sell genuine Probably Stolen Immunivax?

Yes. Thieves who visit your shop (especially when boosted by a Black Lamp) frequently carry authentic vials taken from upper-tier shipments. However, these items count as stolen goods, meaning you must hide them in a Smuggler's Bay to prevent security seizures.

What should I do if a vendor brings a counterfeit syringe?

Do not inject it. If you have the counterfeit or fence path unlocked, you can attempt to alter the label and pass it off to an unsuspecting citizen, but doing so carries severe reputation risks if caught. In most cases, it is safer to reject the trade and preserve your capital.

Where can I buy the Smuggler's Bay to protect my medicine?

Dr. Jackson periodically carries the Smuggler's Bay module in his night shop rotation. Be sure to check his stock whenever you visit him after hours, as protecting your high-tier medication from station security checks is essential for late-game survival.
