Depends how you define "heavily". But any common interpretation of the words heavy drug use; no he is absolutely not correct. Just because there's a few podcasts and reddit threads on what cycles some of the male stars allegedly are on, doesn't mean TNE is heavily used across the whole industry. Don't be ridiculous. Why would they need this any more than you and I while already being on an anabolic stack + viagra?
Ask a source how much they sell test e/c vs TNE and tell me again it's incorrect to tell OP who's confusing the two that it's not often used.
