Back in SPI today — wind is up, so it's time for another "Send It Sundays."

Little tired, but stoked after giving my talk at the Sports Pharmacy Summit down in Fort Lauderdale. Huge shoutout to Sean Casey and the whole crew for putting on an epic event — y'all crushed it.

Had a blast nerding out on HRV and Met Flex, and it was great connecting with so many of you there.

Here's what went down this week

Newsletters:

• ​Cold Water Immersion and Your GainZ: Cold plunges might feel hardcore, but doing them right after lifting can significantly blunt muscle growth—and this breakdown shows when they help vs. hurt your gains.
• ​Cold water, red light, cryo pods, and a testosterone myth so wrong it owes me an apology: Cold exposure isn’t one-size-fits-all—this breakdown explains why method, timing, and context matter, and how to use it without sabotaging your performance or gains.
• ​My massive mistake: An accidental double-dose of a new nootropic turned into a real-world test of clean focus and performance—here’s what actually matters when choosing a supplement that works.

Coming up:

• The Phys Flex Cert will open again on Monday, April 20, 2026, for 1 week. Mark your calendars. Much more info coming up.

Flex Diet Podcast:

• ​Episode 377: Methylene Blue for Mitochondria & Performance: Benefits, Dosing & Risks with Dr. Scott Sherr

Iron Radio:

• ​AI-Peptides​

Instagram posts of the week:

• ​Do ice baths decrease inflammation?​
• ​Struggling with PCOS and insulin resistance?​

Gym Tune of the Week: Anthrax - Live Wacken 2019​

One of my fave bands! Can't wait for their new album! This is a classic full live performance to crush some PRs to in the gym.

Much love,
Dr Mike
