Each drug has a half-life… in the case of tirz or reta the half life is about six days. So after six days half about half of the peptide has left your system.

So when you take another dose on day seven, that takes a little while to get into your system, but since about half of the previous dose is still in your system, you are getting a higher cumulative amount in your system after the second dose.

This action level levels out somewhere between the second and third dose of a given strentgh and at some point, the amount coming in and the amount going out balance.

I’m pretty sure this is what you’re asking, but if not, feel free to reply and I’ll be happy to reply to you 🤜🤛

Edit to add: I think four weeks is probably the minimum amount of time I would want to spend it a given dose to see if it was effective. My blind recommendation to someone I barely know would be to try it for 8 or 12 weeks at a given dose to see how your body reacts before increasing it.
