what our patients are saying
"Peptide therapy wasn’t even on my radar until I came to Extension, but it’s ended up being one of the most impactful parts of my routine. I’m recovering faster, staying more consistent with training, and just operating at a higher level day to day."
Alex
"I was introduced to Peptide injections, which are excellent for skin, hair, joints and bone support. I feel so much better since I started taking this."
Lori
"The BPC+ TB4 peptide has helped me turn back the clock by 10 years, helping bring collagen and volume back to my face, and reduce skin laxity. My friends keep telling me I'm aging backwards. Who needs filler and botox when you have peptides?"
Cindy
