As the title states looking for a test dr. in Long Island. Suffolk county would be ideal. I saw a few recommendations but the posts are over a year old.
I used Men's Restoration Health for over a year - they are on 110 in Melville. They were good but you have to go in every week and it got old for me. They took my insurance and my cost was just my $20 copay.
See the finding a TRT doc link found here: https://forums.t-nation.com/t/about-the-t-replacement-category/38/2?u=ksman
I think they have a Hauppauge as well.
