Pretty badly. Unless you save-scum (or just save edit), you'll end up an 8' tall bull-man with 100% facial masculinity, a 2' horse penis, soccer ball-size balls (21.5 or so), 30 inch bull horns, bovine face, ears, feet and tail. And size 20 Hips and Butt for some reason. Also,
Refractory Rate is the percentage of semen you generate in an hour. At 3100% you recover 31% of your semen each hour, which is kind of ridiculous, and you'll likely want to reduce it (100% is baseline). Especially if you aren't ejaculating 100% of your semen each time.
To undo the side effects of Mino Charge:
Horns can be removed with
ReductPro.
Hight can be reversed by
Strawberry Shortcake.
You probably already know about
Twink-Ease. If you already have Perma-Cute you don't have to worry about facial masculinity/femininity changes.
Most everything else can be reverted with
Terran Treats or your normal TFs.
Tone can be reverted by eating a bunch of
Gryvain Jigglers.
Thickness can be reduced by Running or Swimming at the Ten Ton Gym on New Texas, or training Stamina with Ramis.
Laquine Ears has a
Boost Cum effect (up to 30000 mLs), if Mino Charge has too many side effects for your taste. Incidentally, the 2' equine penis from Mino Charge qualifies you for
Musky Pheromones from Laquine Ears, if you get 3 of Face/Arms/Legs/Tail (+Ears, which are guaranteed), if that's something you find appealing. Heck, if you're going 'dommy', you might want to pick up
Alpha Scent from
Lupinol (Lupine score does not have a genital requirement).
The
Huge Cum Bubble just requires a certain amount of semen (between 10000 and 70000 mls). If you go over 70K mLs, you'll burst the bubble and won't get anything. Gender alignment doesn't matter.
As an aside, this kind of thing is why I carefully plan my TF order. But then, what else are you going to use your huge pile of cash on?
Nope. The cum-increasing effects are tier 4 TFs, which require being ineligible for all lower-tier TFs, which effectively means being a full minotaur with max masculinity.
You don't have to be ineligible for all Tier 3 to get Tier 4 Mino Charge transformations, but it does increase your chances. And without save-scumming, you will almost certainly have all Tier 3 by the time you have 300 Cum Efficiency.
On the possibility of overloading the milkers (300 Efficiency, 51 Cum Multiplier, 21.5 Size):
* Cum, Max: 607,500 mLs (x2)
* Cum, Probable Ejaculation: 77460 mLs
* Cum, Max: 1,215,000 mLs (x4)
* Cum, Probable Ejaculation: 77460 mLs
Edit: It seems you don't need all that much to overload. Just took a 100% full 300 Cum Efficiency, 51 Cum Multiplier to New Texas and proceeded to break the Milker. If I choose to stop: 271100 mLs, so it doesn't use Probable Ejaculation. The 320,000,000 threshold seems to be the 'can't stop' number, not the 'break the machine' number.
Edit 2: It seems the amount of semen required to break the milker is tied to the amount of credits you get? At least on New Texas (line 1062, if you want to double-check me,
@TheShepard256 I'd appreciate your input). If you would make more than 150 Credits, you break the machine if you continue (Comments say 50% chance, I don't see the code for that). If you have more than 320,000,000 mLs of cum, you don't get a choice.
