progestins don't really cause bloat....it's the aromatizable compounds that lead to bloat. deca alone can be construed to cause bloat, but really it's the lack of androgens, so the gains appear "soft". A deca only cycle will a;so leave estrogen dominance, due to very low androgen levels, so the effects of estrogen, even though there really isn't more estrogen, may be more pronounced.Originally Posted by Shredder
