Mutagens in The Witcher 3: Wild Hunt are pieces of genetic material that can be obtained by killing Monsters. These items are infused with the powers of these creatures. There are two types of Mutagens that Geralt can obtain: Regular Mutagens which drop from multiple Monster types and Special Mutagens which drop from specific Monsters. Both types come in either Red, Green or Blue colors which determines their effects. Geralt can slot Mutagens into their respective slots on the Character Sheet in order to activate their abilities. Special Mutagens are also key ingredients in crafting Decoctions.

The Witcher 3 Mutagens Overview
Mutagen Properties
Regular Mutagens
Mutagens have different effects depending on their color, with Red ones providing a percentage bonus to Attack Power, Green providing a flat bonus to Vitality and Blue providing a percentage bonus to Sign Intensity. Note that these colors also correspond to the colors of Geralt's main Skill trees, Red being the Combat Skills, Green being Alchemy Skills and Blue being Signs. Each color of Regular Mutagen comes in three tiers: Lesser, Standard and Greater.
Each tier provides a greater effect than the last. For example, the Lesser Red Mutagen provides 5% boost in Attack Power, while the Red Mutagen and Greater Red Mutagen provide 7% and 10% respectively. Only the Lesser version of each Mutagen color can be obtained as Monster drops, while the higher tiers can be crafted via Alchemy using 3 Mutagens of the tier below (i.e., 3x Lesser Red to craft a Red, 3x Red to craft a Greater Red). With the Blood and Wine DLC, new crafting options become available, allowing you to transmute one color Mutagen for another color of the same tier using various Alchemy Ingredients.
Special Mutagens
Special Mutagens are named after the Monster type they drop from such as the Alghoul Mutagen, which drops exclusively from Alghouls. Each color has a different appearance from those of Regular Mutagens.
These Mutagens have equivalent effects to the Lesser Regular version of their respective color and can be dismantled into such. However, they can be quite rare and are very valuable until you have crafted all of your Decoctions so it is best to save dismantling any extras for later.
Mutagen Usage
In order to activate the effects of a Mutagen, Geralt can slot it into one of 4 Diamond-Shaped Slots on the Character Sheet.
Each of these slots is connected to 3 Ability Slots to which Geralt can assign his learned skills. Matching the color of a Mutagen to the color of the skills attached to its slot will increase the Mutagen's effect by 100% for each skill. For example, slotting a Greater Red Mutagen and then attaching 3 Combat Skills into its connected slots will provide a total of +40% Attack Power (10% bonus for the activated Greater levle Mutagen and another 10% for each skill of matching color slotted).
Not matching slotted skill colors with your Mutagens does not affect you negatively. It just simply does not provide the bonuses, but the Mutagen's effect by itself will still be active.
Note that Special Mutagens can also be slotted to grant the same bonuses as Regular ones. However, their effects are equivalent to Lesser Mutagens only and are more valuable as crafting materials for Decoctions.
Finally, the Blood and Wine DLC introduces the new Mutations mechanic, which uses Greater Red, Green and Blue Mutagens to unlock mutations for Geralt.

Every drowner on Skellige will drop one random lesser mutagen. This way I got 50 lesser mutagens in 10 minutes. Did a short guide on that: https://youtu.be/PrYzhFpAdDY If you lower lvl than go to the abandoned village south of Downwarren in Velen. There will be one alguhl, who drops all kinds of mutagens, also red ones. Meditate to fight him again.

i have about 20 excess noonwraith mutagens, what do i do with them all

I have a lot of "named" mutagens llike "griphin mutagen", "nekker mutagen", ... I think I can remember, that I once saw a possibility to convert a "named" mutagen into a mutagen. As far as I remember it was in Alchemy and was "small mutagen" - converting a small named mutagen into an unnamed mutagen of the same color. But I patched the game and now I cannot find this anny more. I have lots and lots of named mutagens and cannot build normal muragens (for which I would need 3 small mutagens) or greater mutagens - even though I have enough e.a. green mutagens - but all of them not "named" small but Griphon, Nekker, ... But according to their Stats they are small mutagens. Anny clues what to do?
Do Sylvan's have a mutagen? I haven't seen or gotten one. They are Relicts like that fat sylvan posing as the peasants god in the ruins.
