Can you use nolvadex (tamoxifen) to get rid of gynecomastia?

Maybe. Nolvadex (tamoxifen) is effective in reducing estrogen driven gynecomastia. It works to prevent better than to treat the problem and is given prophyllactically when men are given Estrogens to treat various disease states.
Unlikely. Once the breast tissue has grown and developed into true glandular gynecomastia only surgical treatment is effective.
Yes. Although tamoxifen is not fda-approved for this use, multiple studies have been published demonstrating it's benefit treating gynecomastia. It is probably most beneficial early in the development of the disease. If no effect is seen after three months, continuing the drug further is probably not helpful.

Can tamoxifen help me get rid of my gynecomastia?

Great idea. But I wouldn't want to try it outside of a clinical trial.
Don't do it. Tamoxifen is an anti estrogen prescribed for hormonal dependent breast cancer in females also for prevention of breast cancer. I am not aware of the use of tamoxifen in males. Most gynecomastias are caused by medications. Simply lowering the dosis or stopping them there will be improvement. Tamoxifen is indicated for mastalgia (not gynecomastia) in females but not in males.
Probably not. It is an anti-estrogen drug which may keep the condition from getting worse, but it probably won't reverse it.

Will using nolvadex (tamoxifen) help reduce my pubertal gynecomastia?

Not recommended. If you're 38 years-old you no longer have pubertal gynecomastia. This drug isn't recommended for chronic gynecomastia. You should be seen by an endocrinologist for a medical/hormonal evaluation to make sure nothing is amiss.
Surgery Helpful. I have found that gynecomastia, if persistent, is often best treated with partial excision of the prominent glandular tissue as well as liposuction surgery of the peripheral chest area. If the prominence of the chest wall is caused by adipose tissue, then liposculpture surgery alone may suffice. For patients with excess skin, common after weight loss, skin excision may also be necesary.

Is nolvadex (tamoxifen) for getting rid of man breasts or not?

Not intended for. This drug is not intended for this but I understand that there are a few endocrinologists who are using this in an off label fashion for this purpose and there are some illicit anabolic steroid body builders who use this to minimize the development of male breasts. It generally will not reverse existing breast tissue or we would use if for female breast reduction.
