Medical boosters, often simply called boosters, are performance-enhancing drugs in EVE. When consumed, the user gets a temporary boost to a specific combat related attribute or skill training attribute. The more powerful combat-related boosters have a chance of having negative side effects which may impact a user's ability to fight. The weaker boosters, called Synths, have no chance of side effects, but have dramatically reduced effects.

Combat-related boosters are manufactured from gasses which are harvested from anomalies in known space. Mytoserocin gasses are used to make Synth boosters and are found in high and low security space, and cytoserocin gasses, found in low and null security space, are used to create the more powerful Standard, Improved, and Strong boosters.

Skill training boosters are obtained through in-game events, and generally have an expiration date after which they will not function.

There are 8 different abilities that boosters can affect, divided into four different grades.

There are other combat boosters which are not manufactured by players, and which do not have side effects.

To use a booster, right click on it and select “Consume”. This can be done in space or at a station. Each booster type has a different “slot” that it uses, viewable in the character sheet. Pilots cannot use another booster if it occupies the same slot as a currently active booster. These slots are distinct from those used for regular neural implants.

It is not possible to override an booster once it has been consumed - pilots must wait out the drug for its duration. Combat boosters last 30 minutes, increased by 20% (6 minutes) for each level of Skill.png Biology the user has trained.

Each type of booster has four side effects associated with it. When the booster is used, each of these effects has a chance of occurring. A pilot might have no penalties for using a booster, or could experience all four at once. The chance of getting a side effect is 20% for Standard, 30% for Improved, and 40% for Strong. The penalties are -20% for Standard, -25% for Improved, and -30% for Strong. Both the chance of getting a side effect and the potency of any received effect can be reduced by skills and implants.

• Biology (1x): 20% bonus per skill level to attribute booster duration
• Neurotoxin Control (2x): 5% reduction per skill level to booster side effects potency
• Neurotoxin Recovery (5x): 5% reduction per skill level to the chance of having a negative side effect

The Eifyr and Co. 'Alchemist' line of neural implants can enhance the duration of boosters, or reduce the probability or potency of side effects. See implants for more information.

Cerebral Accelerators are boosters that increase the attributes of character, thereby increasing the speed at which they accrue skill points. The attribute bonus given by Cerebral Accelerators varies by type and method of acquisition, but all Cerebral Accelerators boost all attributes by the same amount. Some Cerebral Accelerators provide additional bonuses to combat stats, but most only affect character attributes.

All Cerebral Accelerators occupy booster slot 4, meaning that pilots cannot use two different accelerators at the same time. As noted above, boosters and implants occupy different slots, so pilots are able to use a full set of attribute-boosting implants alongside a Cerebral Accelerator.

The most common sources of Cerebral Accelerators are various deals offered to new players by CCP (e.g. the Steam Super Starter Pack), which allow inexperienced players to experiment with their skill queue during their first few days in New Eden. Cerebral Accelerators obtained by this method are only usable by characters below a certain age (usually less than 15 days old). These boosters will deactivate if a character exceeds the intended age, regardless of the remaining duration.

Cerebral Accelerators obtained via real-money purchases are not available on the regular market, but can be sold via contract.

When a player purchases a subscription package that includes a Cerebral Accelerator of any kind, the Accelerator will be delivered via the item redemption system. To redeem a Cerebral Accelerator:

• Go to the character selection screen.
• If the Accelerator is available to be redeemed, a “Redeem Items” ribbon with be located along the bottom of the screen. Click on this, and a list of all the items available to be redeemed will be shown.
• Drag and drop the Accelerator onto the portrait of the character you want to receive it.
• The item will be delivered to the Item Hangar of the station in which the designated character is currently docked.
  • Note: It is advisable to move the desired character to the station you want the item at before redeeming the item. That way there is zero chance of losing it during transport.
• To activate the Accelerator, right click on it in the Item Hangar and choose “Consume”.

There are also several kinds of Accelerators that have been part of various lore events in New Eden, such as the Crimson Harvest. These Cerebral Accelerators are usable by all characters, regardless of age, but they also come with a built-in expiration date after which they will no longer function. This expiration date is generally some set time period after the conclusion of the event in which they were obtained.
