Please validate my reconstitution measurements and dosage plan

Please validate my calculations on reconstituting and dosage / plan :) Newbie to pep. use. I've been doing research but still am a bit iffy about the calculations and wanted to be sure. I did use a calculator but wanted another set of eyes to check.

I purchased a 15 mg vial of Reta and a 30 mL vial of BAC water.

For recon. I plan on using my 3mL syringe adding in 1.5mL BAC water. (this would be half of the syringe based on markings)

From there, I should have 30 doses at .5mg.

I would then pull 5 units to dose at .5mg. (I regret having 1mL insulin needle + syringe because I feel like the .3mL wouldve been easier to dose with and see)

My plan is to start off at .5mg to assess side effects as I've never used GLPs, then the week after (or after 2 weeks if side effects are excessive) move to 1 mg for about two-three weeks, then increase to 1.5 for two to three weeks, then 2 mg, etc.

I was debating whether or not to start with 0.5mg or 1 mg but a lot of sources say 0.5 is good for starting.

Thank you :D
