The difference between "wet" and "dry" steroids/phs is water retention. Water retention is caused by estrogen through aromatase.
Wikipedia: Aromatase is an enzyme of the cytochrome P450 superfamily (EC 1.14.14.1), whose function is to aromatize androgens (that is, to selectively increase their aromaticity), producing estrogens. As such, it is an important factor in sexual development.
Effectively: Aromatase is when excess testosterone converts to estrogen.
WET:
M1,4ADD
Phera
M1T (and subsequent legal variants/clones)
*Superdrol
DRY:
Bold
Epithios
Tren
*Superdrol
Halodrol
Winztrol
Furazadrol
Prop
STRENGTH:
Tren
Superdrol
M1T(and legal clones)
Phera
M14ADD
On the strength category there are probably more, but from what I hear those are the biggies.
Prohormone Classification
Steroids are classified under 2 categories. Class I has a strong binding to the androgen receptor. Class II does not bind to the androgen receptors, rather it works through other means in the body.
Simply put:
Class I = binds to androgen receptor
Class II = does not.
These prohormones classifications are based on thier steroid counterparts. If there are any revisions needed PLEASE message me.
Class I
Boldenone based phs - 1,4AD & Bold
Trenbolone based phs - Trenadrol & Trenaplex
Testosterone based phs - Methyl 1 Testosterone

Class II
Masteron (Dromostanolone) based phs - Superdrol & Clones
Oral Turinabol (Dehydrochlormethyltestosterone) based phs - Halodrol & Clones
Dianabol (methandrostenolone) based phs - M1,4ADD etc
