What dosages for a cutting stack of dros/tren/test?

Ola all, I recently was looking at a cutting stack that was sold as a mix that had a mix ratio of 100mg/100mg/100mg of:

Drostanolone Enanthate
Trenbolone Enanthate
Testosterone Enanthate
(There is a acetate version as well)

But I’ve had a few people tell me that running a 1:1:1 mix isn’t really a great mix, I’ve just finished a run on Test E (500mg/wk) and have never ran the others, if I were to buy these individually what mg’s should I be running against each other per week?
