What does PT-141 peptide treatment look like?

PT 141 is administered via subcutaneous injection, since other forms of peptides like pills, creams, and sprays have little efficacy. At AgeRejuvenation, a 2-milligram dose is generally effective for men and women about 1 hour prior to sexual activity. Our providers generally suggest starting with a 1-milligram test dose and injecting a similar amount 30 minutes later; testing PT 141 in increments to gauge response is considered the safest approach.

How long does PT-141 take to work?

While some patients respond to PT 141 in minutes, it can take others with sexual dysfunction several hours to notice any changes. Patients will typically see these effects last up to 72 hours following the initial injection.

Does age rejuvenation offer other sexual dysfunction treatments?

AgeRejuvenation offers a variety of hormonal, weight loss, and anti-aging treatments, just like peptide therapy. Other treatments we offer include the P-shot, which helps men with erectile dysfunction. For women, we offer the O-shot to treat low desire, Female Sexual Arousal Disorder, Female Orgasmic Disorder, and dyspareunia, or pain during sexual activity. Both treatments are administered via injection during an in-office procedure.

Tesamorelin, MGF, and Ipamorelin Stack

The Tesamorelin, MGF, and Ipamorelin Stack: Body Recomposition at the Hormonal Level

There is a reason elite performance protocols rarely rely on a single intervention. Real body transformation is not a one-pathway problem. Fat loss is governed by one set of hormones. Muscle growth runs on a different set. Recovery sits on yet another. Hitting all three with a single peptide is like trying to win a championship with one player on the field. The Tesamorelin, MGF, and Ipamorelin stack is what happens when you bring the full team to the game. At AgeRejuvenation's Wesley Chapel, South Tampa, Brandon, Winter Park Orlando, and Winter Garden Orlando locations, this triple-peptide protocol has become a flagship offering for patients who are serious about body composition — not patients chasing fads, but adults who want measurable, durable changes in how they look, perform, and recover.

Why Adult Body Composition Becomes Harder Every Decade

To understand why this stack matters, you have to understand what happens to growth hormone production over time. By the time most patients walk through the doors at AgeRejuvenation, they have already noticed the same uncomfortable pattern: the workouts that used to produce visible results are not producing them anymore. Body fat — particularly in the abdomen — has become harder to lose. Muscle has become harder to keep. Recovery from training takes longer than it used to, and the residual soreness lasts for days instead of hours. This is not laziness. It is endocrinology. Growth hormone production peaks in adolescence and declines steadily through adulthood. By age fifty, many adults produce less than half the growth hormone they produced at twenty-five. IGF-1, the downstream messenger that drives muscle protein synthesis and tissue repair, declines along with it. Sleep architecture changes, reducing the deep-sleep windows when natural growth hormone is released in pulses. The consequence is metabolic and structural. Less growth hormone means more visceral fat, less lean tissue, slower recovery, weaker connective tissue, and reduced exercise tolerance. The standard advice — eat less and exercise more — works against an adult body that is increasingly resistant to both.

How the Stack Works to Support Body Recomposition

What makes this stack so effective is that each component addresses a distinct biological problem. The Stack Strategy: Three Peptides, Three Mechanisms.

Tesamorelin

Tesamorelin is a growth hormone-releasing hormone (GHRH) analog originally developed for HIV-associated lipodystrophy — and specifically validated for its ability to reduce visceral adipose tissue. This is the deep belly fat that wraps around abdominal organs, drives metabolic dysfunction, and is notoriously resistant to diet and exercise. Tesamorelin stimulates the pituitary to release growth hormone in a natural, pulsatile manner. The clinical signature is a lean, defined midsection that returns to a place patients had given up on reaching.

Ipamorelin

Ipamorelin is a growth hormone secretagogue — meaning it triggers growth hormone release through a different receptor system than Tesamorelin (the ghrelin receptor). What makes Ipamorelin particularly valuable is its selectivity. Unlike older secretagogues, Ipamorelin produces clean, sustained growth hormone pulses without elevating cortisol or prolactin. This means the recovery and repair benefits come without the inflammatory or hormonal side effects that limited earlier-generation peptides.

MGF (Mechano Growth Factor)

MGF is a splice variant of IGF-1 produced locally in muscle tissue in response to mechanical loading. MGF activates muscle satellite cells — the dormant precursor cells that fuse with existing muscle fibers to repair damage and add new contractile tissue. Where Tesamorelin and Ipamorelin work centrally through the pituitary, MGF works locally in the muscle itself, accelerating the repair-and-grow response that follows training.

The result of stacking all three is biological coverage no single peptide can provide alone. Visceral fat metabolism, sustained growth hormone signaling, and direct muscle tissue repair — running simultaneously, in synergy.

The Recovery Shift: The First Thing Patients Notice

Patients across Brandon, South Tampa, and Wesley Chapel typically begin noticing changes within the first three to four weeks. The earliest signs are not always on the scale. Sleep deepens — Ipamorelin's effect on growth hormone pulses tends to dramatically improve sleep architecture, and patients wake more rested than they have in years. Recovery between workouts shortens. The morning soreness from heavy training becomes less punishing.

Who Should Consider This Stack?

The Tesamorelin, MGF, and Ipamorelin stack is not a beginner protocol. It is designed for adults who already train consistently, who are committed to nutritional discipline, and who are willing to invest in a precision protocol to break through plateaus that simpler interventions cannot solve. Specifically:

Athletes and former athletes who want to recover the body composition they had a decade ago

High performers in demanding careers who need physical resilience to match their professional output

Adults in their 40s, 50s, and 60s who want to age with strength rather than fragility

Patients with stubborn visceral fat that has resisted diet and cardio

Individuals who have plateaued on testosterone replacement therapy alone

Adults preparing for sports, competitions, or significant physical events

The stack is not appropriate for patients with active malignancy, certain endocrine conditions, or other medical contraindications. Every protocol begins with a thorough medical evaluation to confirm fit.

How This Stack Fits Into a Complete Performance Protocol

At AgeRejuvenation, this peptide stack is rarely deployed in isolation. The most effective body recomposition protocols layer multiple interventions, each targeting a different aspect of hormonal and metabolic health. Common approaches include:

Tesamorelin + MGF + Ipamorelin plus testosterone optimization

Tesamorelin + MGF + Ipamorelin plus hormone optimization for women

Tesamorelin + MGF + Ipamorelin plus GLP-1 medications

Tesamorelin + MGF + Ipamorelin plus NAD+ and recovery protocols

Tesamorelin + MGF + Ipamorelin plus comprehensive metabolic optimization

The Protocol Approach at AgeRejuvenation

The stack is administered as a series of subcutaneous injections, typically self-administered by patients after initial training. Tesamorelin and Ipamorelin are most often dosed daily, while MGF is dosed strategically around training sessions to take advantage of its local muscle effects. Every protocol is preceded by comprehensive labs: hormone panels, IGF-1 levels, metabolic markers, and body composition analysis. Throughout the protocol, the medical team tracks these markers along with subjective performance and physique outcomes. Doses are adjusted based on response, side effects, and goals. The goal is not to deploy a generic protocol but to design a precise intervention based on each patient's actual biology. Dr. Dawn Ericsson, Chief Medical Officer at AgeRejuvenation, oversees clinical protocols across all five Florida locations. Her team includes nurse practitioners, performance coaches, and patient care advisors who work together to ensure every patient gets results that justify the investment.

What Patients Report Over Time

The benefits of this stack unfold across different timescales. In the first weeks, the most consistent report is improved sleep architecture and shortened recovery between workouts. By weeks six through eight, the visible changes start emerging. The midsection tightens. Visceral fat begins responding to the Tesamorelin component, often producing the kind of waist measurement reduction that diet alone could not achieve. Muscle tone increases — particularly in patients who are training consistently and consuming adequate protein. By months three through six, the cumulative effect is what most patients describe as a transformation. Body composition has shifted measurably, lean mass has increased while fat mass has decreased, and energy levels have stabilized at a higher baseline. Performance metrics — strength, endurance, recovery — track upward. This is not the kind of result that comes from any one of these peptides used alone. The stack works because the components compound on each other.
