I've got acne on my shoulders and a bit on my back from my last cycle, I can get some topical tetracycline. I did a search and saw that tetracycline inhibits protein synthesis, but I think that most of the posts were about tetracycline in pill form. I was wondering if any one has any experience with the topical tetracycline and if it would still inhibit protein synthesis and if you think it would be worth taking while on cycle or should I wait until I'm off... let me know what you guys think.
