I havesaggy chest which i tink is gyno, i workout a lot at the gum to build chest but d nipple area remais soft.i'm havin late puberty, will d lumps go?

Depends on the situa: Pubertal gynecomastia will occur in 1/3 to 1/2 of males & generally last about a year before fading.Up to 3 years is noted occasionally before disappearing. Overweight kids can appear to have it from just fat accumulation.If present after 3 years, surgical removal of the glandular tissue & liposuction of any associated fatty tissue will do the job.

Possibably: If you are still going through puberty then they might go away. Sometimes guys will be left with a little fat pocket on the breasts after puberty and liposuction is the only way to get it off if you are already at a good weight.
