I just bought 8 kits of saizen and im hoping it will last for 4 months. How do I take it and will 8 kits last for 4 months? Is it true each kit lasts for 10 days and im supposed to be on for 5 days and be off for 2 days? And lastly how many IU's do I take a day. Its my first time with this stuff so I confused.
