"Bold is a good drug, its just not very strong."
don't expect much gains on 300mg of bold. Just think of it as a support drug purely for collogen synthesis, RBC and hunger.
If you want more gains, run some nandrolone instead. But your proposed cycle is fine for its intended purpose.
Don't get carried away with some magic ratio. Everyone have their own sweet spot.
The all time popular 500 test + 400 deca
is probably based on 2 amps of sust + 2 shots of norma deca@200mg per ml. You can run any dosages 325, 530 etc. It doesn't have to be a whole number. We all got calculators right?
