Agreed, I'd stay away from pro hormones they have ben reported by many to produce gyno. If you going to use them, use an anti estrogen during and after.

very very few pros convert to estrogen

can you elaborate on that, which convert and which don't convert?

heading to work right now. There are very few that do. I will try to find some that actually do when i get home

I've taken a few and have needed nolva with all of them so would be interested in which ones don't convert

these are all NO, very low, and even anti estrogenic
1,4andro
Dymethazine
MENTABOLAN
EPISTANE
MAX-LMG
18-methylestr-4-en-3-one-17b-ol (deca derivative)
METHYLSTENBOLONE
TRENAVAR
Methyldiazirinol
DIMETHANDROSTENOL
METHYL 1-AD
METHYLCLOSTEBOL
HALODROL
TRESTOBOL
HEXADRONE
FURAZADROL

So what about "delayed gyno" and the products you mentioned?

Also, I heard that most pro hormones out there that don't need any cycle assist or pct are normally to mild to get any gains from

delayed gyno would not happen since there is no conversion. That happens when running a compound that aromatizes and once your AI wears off and estrogen levels rebound.
any prohormone needs to be taken with on cycle support

Thats not what he asked, he asked about delayed gyno,
Delayed gyno is caused by estrogen suppression during the cycle and then causing a rebound after the cycle

that is what i said no?
