any cycle with 3-day off is not recommended. I would rather choose EOD over anything that requires you to pause for 3 days. Lol. Anyway, you can go with 2 on 1 off, 5 on 2 off, 3 on 1 off and the list goes on.
Try EOD. So far, many users can prove that it is one of the most effective cycle. Also, it helps you save peptides/HGH. This cycle can help you make your supply last a little longer than the usual.
3 off? You better not do this. Skipping peptides or hgh for three consecutive days when you are on your cycle is definitely a NO! 5on2off would be great though - anything as long as it does not involve 3 consecutive off.
Please, no! Stick with your 5on 2off cycle. If you are really eager to save money, then try to run 4on 2off or EOD instead of 4on 3off. 3 consecutive days of not using peptides will definitely have an impact on your 4on.
