primo, turkish legit, use often: I like it. Hard musculature subjectively, little water retention, less sides, somewhat weak, anavar-ish
deca, normas and yellows, use often: I love it. Giant growth, a little soft and floppy, but oh so hypertrophic, subjective sense of increased blood pressure, no sexual sides in contradistinction to rumour, some back acne, but kind to face and arms. My favorite. Would take 700 primo for me to equal 400 Deca. Deca twice as strong (anabolically) and half as costly. But lacks a sense of mental clarity and upbeatness I find in primo. A little muddled (progesterone?) at times.
Hope that helps.
I mass with Deca 600ew (this is high, 400ew for new to deca, or officially 2mg x wt in pounds = dose ew of deca) with test and dbol. I cut with primo 300-400ew pretty much alone or with anavar. GH is good sprinkled on either cycle.
This is a subjective, personal opinion. This is NOT my scientific opinion (that which you specifically excluded from discussion). Hope this helps.
