The Acid Lab: the complete business guide

The Acid Lab is the best business in GTA Online for a solo player, and it is not close. It arrived with Los Santos Drug Wars in December 2022, runs out of the back of a lorry, costs almost nothing to start, and pays out with a single delivery vehicle and none of the convoy stress the older businesses inflict. In 2026 it is the standard first purchase advice for a reason: it pays for itself in six or seven sells and then just keeps going.

This guide is the full loop: unlocking it for free, the one upgrade that matters, the supply-and-sell rhythm and the daily boost, with the verified numbers underneath. Figures are checked against current tracked values as of early August 2026.

Step 1: unlock it, and get paid to do so

• Take the call from Ron and run the First Dose missions, six story missions around the Freakshop with Dax and the Fooligans
• The missions themselves pay around GTA$600,000 all told, so the unlock is profitable before the business even exists
• Finishing them hands you the Freakshop as a base and the Brickade 6x6 lorry that houses the lab, free
• It also awards the Ocelot Virtue free, a fast electric supercar worth over GTA$2 million in the shops, so the unlock chain pays you twice
• There is no property purchase anywhere in this chain, which is why this is the standard first-business advice for new players

Step 2: buy the only upgrade that matters

• Run Fooligan jobs for Dax until the equipment upgrade unlocks, then buy it for about GTA$750,000
• It speeds production and lifts the value of every batch from that day on, and it is the best upgrade-per-pound purchase in the game
• That GTA$750,000 is the entire meaningful cost of this business, and at full batch values it pays itself back in six or seven sells

Step 3: run the loop

• Buy supplies from the lab screen rather than stealing them; the maths favours cash sourcing once the upgrade is in
• Production runs in the background while you do literally anything else: heists, races, other businesses
• Trigger the daily production boost at the Freakshop when you pass through, it speeds the batch by half and costs nothing

Step 4: sell

• A full batch with the upgrade sells for GTA$335,200, and the daily boost pushes effective earnings toward the GTA$385,000 figure trackers report
• Every sell uses a single delivery vehicle, solo-friendly by design, roughly ten minutes of work
• Self-supplied and sold on rhythm it clears GTA$100,000 an hour net without ever being your main activity

The reference layer

The whole case in one paragraph: setup cost effectively GTA$750,000 after a profitable unlock, GTA$335,200 per full upgraded batch, over GTA$100,000 an hour self-supplied, one delivery vehicle every time, and production that never asks for your attention. There is no raid stress and no crew requirement. The one honest limitation is scale: it will never pay like a Kortz week or a Cayo run, because it is the reliable floor underneath those, not the ceiling. Buy it first, keep it running forever.

Where it fits

The 2026 solo stack is built on exactly this: the Acid Lab as your active floor, a Nightclub accruing passively behind it, and heists as the spikes on top. Our heists comparison lays out the spike side, and the online desk at sixcentral.co.uk/online carries every guide, on the site and in the SixCentral app.

Free to unlock, paid to learn it, one lorry, one delivery, forever. Dax would call it the peoples business, and for once the Fooligans are right.

Why it is the best first business in the game

Three reasons, and they compound.

• The effective cost is around GTA$750,000 rather than the sticker price, because the unlock missions pay you along the way and the Brickade that houses the lab is free.
• It is entirely mobile. The lab lives in the back of the truck, which you can request anywhere, so there is no property to drive to and no fixed sell location to be camped at.
• Sell missions are short and can be completed solo without the truck being an obvious target the way a Bunker convoy is.

For a new player with under a million to spend, nothing else turns that money into a permanent income floor this quickly. Six or seven full sells and it has paid for itself.

Supplies: steal or buy

You can resupply by buying or by running a supply mission. The maths here is different to most businesses because the Acid Lab batch is small and quick.

Buying supplies is the right call almost always. The supply missions take longer than the value they save, and the whole appeal of this business is that it runs in the background while you do something that pays better. Buy, walk away, come back and sell.

The upgrades that matter

Equipment Upgrade is the one to buy. It speeds up production and increases the value of each batch, and it pays for itself well inside the life of the business.

The other upgrades are cosmetic or convenience. The MK II weapon workshop that can be fitted to the Brickade is genuinely useful though, because it means you can convert weapons to Mk II without owning a Kosatka, an Avenger or a Mobile Operations Centre. For a lot of players that is the cheapest route into the Mk II system by a wide margin.

Running it alongside everything else

The Acid Lab is not a business you sit and watch. The correct pattern is to start production, go and do a heist or a set of contracts, and come back when the bar is full.

• Resupply at the start of every session, before you do anything else.
• Sell when the batch is full, not before. Partial sells waste the trip.
• Full batch pays GTA$335,200, which works out over GTA$100,000 an hour self-supplied.
• Solo sell missions from the Acid Lab are among the safest in the game. There is no convoy to split and no slow vehicle to protect.
• Sessanta calls a lot. You can ignore her.

Where it sits in 2026

The Acid Lab is not the highest earner in GTA Online and it has never pretended to be. What it is, is the most reliable floor: a business that quietly pays a hundred thousand an hour with almost no risk, no property to defend and no crew required.

Buy it first, keep it running forever, and let the heists provide the spikes on top.
