Working with Chris Duffin on Peptides
Recently, I started working more closely with Chris Duffin, who is coaching me on peptides. Chris has been in this space for well over a decade, going back to when Stan Efferding and others first began experimenting around 2010. I’ve dabbled with GHRP and BPC-157 in the past, but right now I’m taking his KLOW blend (K-L-O-W), which combines four different peptides. Alongside that, I’m using AOD and ARA as part of my healing and fat-loss focus.
Chris is deep into the research and practical application, so for anyone who doesn’t want to sift through endless studies and anecdotal reports, I highly recommend working with him. He’s offering coaching services, and his peptide store has a discount code you can use: Carroll15pers (capital “C,” lowercase “arroll15pers”) for 15% off.

Rehab, Training, and Support
I’m still in a bit of a rehab state following my hamstring and adductor injuries and the surgeries I’ve had. I’ve been working closely with Dr. Joe Camisa, a master clinician, who’s helped me make progress with specific adductor rehab movements. In addition, I’ve been getting shockwave and ultrasound therapy from Mary D. “Dee Dee” Vale in Jacksonville, Florida, which has been a big help in keeping the tissue moving in the right direction.
Between rehab and life demands with work and my kids, I haven’t been able to dedicate as much time as I’d like to training. But I’m staying consistent, being patient, and working to build myself back to where I want to be.
Training Routine Right Now
My current program is simple but steady:
- Daily big three: core stability staples (bird dogs, McGill curl-ups, and side planks)
- Adductor work: every other day with adequate rest for healing
- Walking: up to an hour a day, often broken into morning, afternoon, and evening walks
- Machine work: sprinkled throughout the week to keep general strength and blood flow
The focus remains on healing, fat loss, and rebuilding. I’ve finally started approaching the 250 lb mark and below—something I once thought would come quickly after my big squat five years ago, but in reality, it’s taken a lot of work, dialing back food, and adding in the right peptide support.
Looking Ahead
I’m planning to bring back more benching and squatting as my pecs and adductor continue to heal. It’s not the most exciting training to watch or read about right now, but I’ve always promised to be real about where I am. Progress is being made, and I’m grateful for the help I’m getting from Joe, Chris, and Mary.
