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.

Rapamycin Therapy

Rapamycin Therapy: Possibly the Most Studied Longevity Drug in Existence

Rapamycin is not new. It was discovered in the 1970s in soil samples from Easter Island — Rapa Nui, the source of its name — and has been used safely in human medicine for decades to prevent organ transplant rejection. What is new is the recognition that the same biological pathway Rapamycin targets to suppress transplant rejection turns out to be one of the most important regulators of aging itself. In every major model organism studied — yeast, worms, flies, mice — Rapamycin extends lifespan. It does this in the context of robust randomized trials, not anecdotes. It is the only pharmaceutical agent to have been demonstrated to extend lifespan in mammals in independently replicated studies through a federally funded program designed specifically to find such compounds. For a serious longevity practitioner, ignoring Rapamycin is no longer a defensible position. At AgeRejuvenation's Wesley Chapel, South Tampa, Brandon, Winter Park Orlando, and Winter Garden Orlando locations, Rapamycin is offered as part of a comprehensive longevity protocol — not as a standalone fix, but as one of the most evidence-supported tools available for adults serious about extending healthspan.

What mTOR Is and Why It Matters So Much

To understand why Rapamycin matters, you have to understand mTOR. The name stands for mechanistic target of rapamycin — and it is one of the central regulatory hubs of cellular metabolism. mTOR functions as a sensor, integrating signals about nutrient availability, energy status, oxygen levels, and growth factor signaling. Based on those inputs, it directs cells either to grow, replicate, and synthesize proteins — or to slow down, conserve resources, and engage in self-repair. When mTOR is highly active, cells are in growth mode. This is appropriate during development, during recovery from injury, or when there is genuine need to build new tissue. When mTOR remains chronically activated — as it tends to in modern adults eating constantly, sleeping insufficiently, and never genuinely fasting — the cellular environment shifts away from repair and toward continuous, low-grade growth and protein synthesis. This sustained mTOR activation has consequences. It suppresses autophagy, the cellular cleanup process that removes damaged proteins and dysfunctional organelles. It accelerates cellular senescence. It contributes to the chronic inflammatory state that drives most age-related diseases. And it is, increasingly, recognized as one of the central drivers of the aging process itself. Rapamycin, true to its name, partially inhibits mTOR. The result is a pharmacologic shift away from growth and toward repair — the same biological state that intermittent fasting, caloric restriction, and certain forms of exercise produce, but achievable through a controlled, periodic intervention.

How Rapamycin Works to Support Cellular Cleanup

What makes Rapamycin unique is its effect on autophagy. The concept that gets most patients interested in Rapamycin is autophagy. The word means "self-eating," and it refers to the cellular process by which cells identify damaged components, package them up, and break them down for either disposal or recycling.

Autophagy activation

mTOR modulation

Periodic dosing strategy

The longevity dosing of Rapamycin is fundamentally different from transplant medicine. Instead of daily high-dose administration, longevity protocols use intermittent, low-dose strategies — typically once-weekly or once every several weeks. At intermittent doses, the drug appears to selectively inhibit one of the two mTOR complexes (mTORC1) while largely sparing the other (mTORC2). This selectivity is critical, because many of the side effects associated with continuous Rapamycin use trace back to mTORC2 inhibition.

The Cellular Repair: The First Thing Patients Notice

The honest answer is that most patients do not feel dramatically different on Rapamycin in the short term. Unlike stimulants or hormone therapies, the effects of Rapamycin do not announce themselves through immediate symptom changes. The benefits accrue at the cellular level over weeks, months, and years — and they are often best measured through biomarkers rather than subjective experience. That said, patients running well-designed Rapamycin protocols at AgeRejuvenation often report several patterns over time. Recovery from physical activity tends to improve. Inflammation, both as a biomarker and as a felt sense of stiffness or discomfort, often decreases. Some patients notice improvements in metabolic markers — fasting glucose, insulin sensitivity, lipid panels. Skin quality often improves over the course of months as autophagy supports more efficient cellular renewal. The most powerful effects of Rapamycin, however, are the ones patients will never notice in the moment — the slowing of cellular aging processes, the protection against age-related disease, the cumulative impact on healthspan and lifespan. These are the effects that justify the protocol, and they are the effects that show up most clearly over the long term.

Who Should Consider Rapamycin?

Rapamycin is not a casual intervention. It is a serious longevity tool that requires careful patient selection, appropriate dosing, and ongoing monitoring. The patient profiles that benefit most include:

Adults focused on serious longevity strategy: patients who think about aging strategically, who track biomarkers, and who are willing to commit to multi-year protocols

High performers seeking long-term healthspan optimization: executives, professionals, and other adults who have a strong interest in maintaining cognitive and physical function for as long as possible

Patients with metabolic concerns: insulin resistance, prediabetes, and metabolic syndrome are downstream consequences of chronic mTOR activation

Adults with strong family histories of age-related disease: cardiovascular disease, neurodegenerative disease, and cancer all have connections to chronic mTOR activation and inadequate autophagy

Patients pursuing comprehensive longevity protocols: Rapamycin works best as part of a broader strategy that includes peptide therapy, hormone optimization, mitochondrial support, and disciplined lifestyle protocols

Rapamycin is not appropriate for everyone. Patients with active infections, certain immune conditions, poorly controlled diabetes, or other specific medical situations require careful evaluation. The medical team at AgeRejuvenation conducts thorough baseline assessment to determine appropriateness.

How Rapamycin Fits Into a Complete Longevity Stack

At AgeRejuvenation, Rapamycin is rarely deployed in isolation. The most powerful application of Rapamycin is as one component of a comprehensive longevity strategy. The protocols at AgeRejuvenation typically combine Rapamycin with several complementary interventions. Common stacks include:

Rapamycin plus SS-31 (elamipretide)

Rapamycin plus Epithilon (Epitalon)

Rapamycin plus NAD+ therapy

Rapamycin plus hormone optimization

Rapamycin plus peptide therapy and lifestyle protocols

Peptide therapy — including GLOW for regeneration, KLOW for gut health, and others — addresses the specific tissue and system-level concerns that benefit from targeted intervention alongside the more global effects of Rapamycin. Strength training, time-restricted eating, quality sleep, and stress management all interact with mTOR signaling and autophagy. Rapamycin works best in patients whose lifestyle creates a supportive biological context for the drug's effects.

The Protocol Approach at AgeRejuvenation

Every Rapamycin protocol begins with thorough baseline evaluation. The medical team reviews medical history, current health status, family history, and longevity goals. Lab work establishes baseline biomarkers — including markers of metabolic health, inflammation, and other relevant indicators. The drug itself is administered orally, typically once weekly or on another intermittent schedule. Doses are titrated based on individual response and tolerability. Patients receive ongoing monitoring with periodic lab work and clinical check-ins to ensure the protocol is producing the desired effects. The goal is not to deploy a generic protocol but to design a precise intervention based on each patient's actual biology. Rapamycin therapy for longevity is precision medicine, not pharmacy-counter prescribing. The dose, timing, monitoring, and integration with other therapies all require clinical expertise built specifically for this kind of advanced longevity work. AgeRejuvenation has built nearly two decades of that expertise. Dr. Dawn Ericsson, AgeRejuvenation's Chief Medical Officer, leads protocol development across the practice's five Florida locations.

What Patients Report Over Time

The benefits of Rapamycin unfold across different timescales. In the first weeks and months, most patients do not feel dramatically different in the short term. The benefits accrue at the cellular level over weeks, months, and years — and they are often best measured through biomarkers rather than subjective experience. That said, patients running well-designed protocols often report several patterns over time. Recovery from physical activity tends to improve. Inflammation, both as a biomarker and as a felt sense of stiffness or discomfort, often decreases. Some patients notice improvements in metabolic markers. Skin quality often improves over the course of months. Rapamycin is generally a long-term intervention. The benefits accrue over years, and protocols are typically designed for sustained use with periodic adjustment based on biomarker data and clinical response. The most powerful effects are the ones patients will never notice in the moment — the slowing of cellular aging processes, the protection against age-related disease, the cumulative impact on healthspan and lifespan.
