Peptides for Weight Loss

Here's something most people don't realize: some of the most effective weight-management medications available today are peptides. GLP-1 receptor agonists like semaglutide and tirzepatide are peptide-based — and for eligible patients, they've changed what's possible in medical weight management.

The key is using them well: as part of a structured plan that protects muscle and is monitored over time, not a shortcut handed over and forgotten.

The context

Why weight resists after 45

Metabolism slows, muscle is harder to hold, hormones shift, and insulin sensitivity tends to drop. The strategies that worked at 30 quietly stop working — not for lack of effort, but because the underlying biology changed. The good news: these are measurable systems, and a plan can be built around the body you actually have.
How it may help

How GLP-1 peptides work

For eligible patients · Results vary
  • 01

    Appetite & blood sugar

    GLP-1 receptor agonists work with your body's own appetite and blood-sugar signaling to reduce hunger and support fat loss.

  • 02

    Semaglutide

    A GLP-1 receptor agonist that can help support appetite regulation and weight loss as part of a broader plan.

  • 03

    Tirzepatide

    Acts on two receptor pathways, GLP-1 and GIP, rather than one. Whether a single-pathway or dual-pathway option fits you is a clinical decision made with your provider. Individual response varies.

  • 04

    Tools, not shortcuts

    Best paired with adequate protein, strength training to support muscle, and oversight for side effects — mostly mild GI, eased with careful titration.

Supporting muscle through weight loss. Losing weight in midlife without losing muscle is the whole game. Our protocols emphasize protein, resistance training and biomarker tracking, with the goal of supporting lean mass through the process. Individual results vary.

Low noise. High signal.

An honest word on the evidence

GLP-1 receptor agonists are among the better-studied peptides in this space, but they're still tools that demand oversight — dosing, side-effect management and supporting lean mass all matter. The semaglutide and tirzepatide prescribed through ACT 2 Health are compounded preparations, and clinical trial results for branded GLP-1 products do not apply to them. We keep it clinician-led, with honest expectations and monitoring on a regular cadence.

Results vary. Clinical trial results apply only to the FDA-approved branded medication specifically identified and do not apply to compounded medications. All medications must be prescribed by a licensed provider based on medical necessity.

The bigger picture

Part of a complete metabolic plan

GLP-1 therapy sits inside our broader medical weight loss program, and weight resistance is sometimes a hormone story too — see hormone optimization. We treat the system, not a single number.

Questions

Frequently asked questions

  • Yes. GLP-1 receptor agonists like semaglutide and tirzepatide are peptide-based medications. For eligible patients we offer them as part of a structured, monitored plan.

  • Some muscle loss can occur with any significant weight loss. Our protocols emphasize protein, resistance training and ongoing monitoring to support lean mass. Individual results vary.

  • Neither is “better” as a general matter. The two act on different numbers of receptor pathways, and the right choice is individual. Your provider decides with you. We do not publish comparative outcome figures for compounded medications.

  • Not necessarily. Your protocol is reviewed and adjusted over time; some members taper as habits and biomarkers improve. It's decided together, based on your data.

  • Results vary, and sustainable change is the goal. We track progress on a regular cadence rather than chasing a fast number.
