Hi Master probably you should stay with normal potency products like test E, Cyp everything under 300mg per ml. Because i can tell you test 400 is super potent but some people dont absorb well such mg per ml and also Big N Full is a very potent boy but some people cant handle it. When i use this big boys i always put only half ml on each shoot and always mixed with other compounds to get better absorbed . I shoot every day but is much better to absorb.

Anything you need support ask brother
