As of now the main source of Trenbolone is from implants for cattle being converted into an injectable or transdermal compound, from powder, and of course Underground Labs. “Home brewing” powder or cattle implants seems to be the preferred method of obtaining injectable Trenbolone Acetate, because the user would have much more control over the potency and sterility of the drug. Trenbolone is much more expensive than other anabolic steroids ranging from 15 dollars per gram of powder or 150 for a single 10 ml bottle. The cost of Trenbolone should not matter, it is worth every penny.
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.
A larger study with longer follow-up concluded that "use of DMPA during pregnancy or breastfeeding does not adversely affect the long-term growth and development of children". This study also noted that "children with DMPA exposure during pregnancy and lactation had an increased risk of suboptimal growth in height," but that "after adjustment for socioeconomic factors by multiple logistic regression, there was no increased risk of impaired growth among the DMPA-exposed children." The study also noted that effects of DMPA exposure on puberty require further study, as so few children over the age of 10 were observed.
