Hello, i got 10 ml macrolane 1 year ago and now got sone voluma. For a 5,5 \" penis you should gain around0,5\" / 10 ml . I liked the result maybe a bit less in the
Foreskin and to me it felt more firm than voluma ( but i also think macrolane may have been better i jected. The key with this product is to go gradualky as it tend to aglomerate if you put too much. I would say stay away from clinics who propose to inject you 30 ml in one shot its probably not the recipe for a nice outcome. Preferably 7+3 of touch up is the bes way to go
