Testosterone dose-response relationships in healthy young men
http://ajpendo.physiology.org/content/281/6/E1172.full
Sixty-one eligible men were randomly assigned to one of five groups. All received monthly injections of a long-acting GnRH agonist to suppress endogenous testosterone production. In addition, group 1 received 25 mg of testosterone enanthate intramuscularly weekly;group 2, 50 mg testosterone enanthate; group 3, 125 mg testosterone enanthate; group 4, 300 mg testosterone enanthate; and group 5, 600 mg testosterone enanthate. Twelve men were assigned to group 1, 12 to group 2, 12 to group 3, 12 to group 4, and 13 togroup 5. Testosterone and GnRH agonist injections were administered by the General Clinical Research Center staff to assure compliance.
FF to results;
Given the results of the study and based on years of personal experience I believe the first time user can safely use between 300-600 mg of testosterone enanthate or cypionate per week for 8-12 weeks. Because it is desirable to have even blood androgen levels I advise at least 2 equal injections per week. Testosterone cypionate peaks within 1-2 days after injection and falls off to almost baseline by day 10. Therefore waiting 7 days between injections of cypionate would cause wide fluctuations in blood androgen levels.
thanks
