Too many variables that could factor in the answer to give you a definitive one.

Good with 600-1gm per week. My opinion is you can get the same if not better results with other compounds with lower dosages at a cheaper price and not be injecting 6-10 ml per week in every limb you have.

I've been taking that and only that since 1991. I cycle every other year.
Im very happy with it and so are the women in this town!
Just don't forget your PCT thats were i screwed up.

So you've done 1 cycle every other year of only primo for the past 15 years? How have your gains been? (this is a serious question btw)

On Topic: I like it at 700mg/week with Tren for cutting cycles. IMO it doesn't have much use in cycles done for mass/strength.

I just started running it at 1G a week. So we'll see.. Im running mast Tren and test too, big stack for 15 weeks then test prop for a month then coming off.
