A guy i lift with just recently asked me a question about the Test Cyp in which he was taking and how frequent and what amount should his injections be. I have read a lot about it and have used it several times and I am currently. His question was, is 500 mg once a wk enough. I told him I personally administor every 300mg every three days myself and always have. I understand that Cyp can remain stable in blood with single weekly injections but personally i have seen better results IMO with more frequent injections. Any input from people with more experience? I hate giving someone the wrong info... i have done a considerable amount of research myself and told him that every 3-5 was a more realistic timeline. Anyone with other opinions?
