Starting peptide question

Anxious to start a Tesa/Reta stack once peps arrive in next couple days. Problem is we are traveling internationally in late July so wondering if it’s worth starting in a few days 6/5ish and stopping 7/19ish for our trip that is 11 days or just wait until we get back and fully start then and can go uninterrupted for a minimum 3 months. Any feedback is appreciated.
