The VALidity Podcast
The VALidity podcast discusses and educates on scientific topics relevant to your health and fitness. Valentina Rodriguez earned her Master's degree in Exercise Science with a concentration in Physique Enhancement from USF while working under Dr. Bill Campbell as his research coordinator. This podcast brings you everything she learned–basically a free master's education!!
Every week, she'll cover new topics in training, nutrition, fat loss, muscle gain... really anything that could be pertinent to your fitness goals.
We get into the concepts, the research, the nitty gritty science so come ready to learn.

Retatrutide Explained | Peptide Series Pt. 1
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
Welcome to Part 1 of our Peptide Series, where we break down the science behind today’s most talked-about compounds–starting with retatrutide.
In this episode, we dive into the mechanism of action of retatrutide, the first GLP-1, GIP, and glucagon triple agonist, and why it represents a major shift in obesity pharmacology.
We cover:
- What GLP-1, GIP, and glucagon receptors actually do
- How retatrutide drives satiety, insulin signaling, and energy expenditure simultaneously
- Why adding glucagon changed the game
- A clear breakdown of the clinical trial data so far
- How retatrutide compares to current drugs like semaglutide and tirzepatide
This episode is your mechanism-first foundation for understanding where peptide-based fat loss is headed.
