Some side effects of prohormone supplementation can include acne breakouts, temporary hair loss, and increased sensitivity of the breast tissue. To help minimize these undesirable side effects, many users add a process known as post cycle therapy. Completing post cycle therapy entails taking an additional supplement that will offset spikes in testosterone levels and clear any toxins that have accumulated in the liver. Since prohormones are processed and broken down in the liver, it can add more stress on this organ than normal. These supplements can also lead to increases in blood pressure, which is another reason why post cycle therapy is a good idea.
This Food Additives Status List, formerly called Appendix A of the Investigations Operations Manual (IOM), organizes additives found in many parts of 21 CFR into one alphabetized list. Additives included are those specified in the regulations promulgated under the FD&C Act, under Sections 401 (Food Standards), and 409 (Food Additives). The Food Additives Status List includes short notations on use limitations for each additive. For complete information on its use limitations, refer to the specific regulation for each substance. New regulations and revisions are published in current issues of the Federal Register as promulgated. Also refer to the Food Ingredient and Packaging inventories in the Foods section of the FDA web site to review several FDA databases of additive categories. For example, the EAFUS list (Everything Added to Food in the United States), is a helpful reference within the limitations described at the beginning of the database.
