The pattern behind declining performance usually starts here.
Testosterone influences energy, cognition, body composition, mood, recovery, and drive. When it declines, the effects compound across every system. Most men are told their levels are 'normal for their age' because conventional reference ranges include chronically ill and elderly patients. We look at where you function best, not where the population average falls.

What It Is
Testosterone is the primary androgen responsible for energy, body composition, mood stability, cognitive sharpness, libido, and cardiovascular health in men. When levels decline, the effects compound: fatigue that sleep does not fix, mental fog that coffee cannot cut through, a body that no longer responds to effort the way it used to.
The standard approach checks total testosterone, sees a number within the reference range, and calls it fine. But a total testosterone of 350 ng/dL is technically 'normal' while being nowhere near optimal. We evaluate the full hormonal context: free testosterone, SHBG, estradiol, DHT, LH, FSH, prolactin, thyroid markers, metabolic panels, and more.
Symptoms like persistent fatigue, brain fog, loss of strength, irritability, poor sleep, and reduced libido often trace back to a hormonal pattern that becomes clear only when you look at the complete picture instead of a single number.
Delphi protocols use bioidentical testosterone cypionate, managed by Kerrie Reynolds, NP-C, with estrogen management (anastrozole) when indicated and HCG for patients who want to preserve fertility. Every protocol is built around your labs, symptoms, and goals.
Who It's For
What's Included
All protocols medically reviewed by Dr. Ann Drayton, M.D., Medical Director
The Process
Full Blood Panel
We order the full panel: not just testosterone, but free T, SHBG, estradiol, DHT, thyroid, metabolic markers, and more.
Clinical Consultation with Kerrie Reynolds, NP-C
A thorough consultation to review your lab results, discuss your symptoms and goals, and design your personalized protocol.
Personalized Protocol Delivered to Your Door
Medications ship directly to you from a licensed pharmacy. We start conservative and optimize based on how you respond.
Regular Monitoring and Adjustments
Follow-up labs at 6-8 weeks, then quarterly. We adjust until you feel optimal, not just 'normal.'
If this sounds familiar
A significant portion of our patients come to us after trying something similar somewhere else and not getting results. In most cases, the protocol was under-dosed, the labs were incomplete, or another condition (thyroid, cortisol, nutrient deficiencies) was never addressed alongside the primary one. We are used to untangling these situations. If you have been on a protocol that did not work, bring your old labs. There is almost always a reason.
What Patients Experience
Common Questions
How is Delphi different from Hims, Ro, or other online TRT clinics?
Most telehealth TRT clinics use cookie-cutter protocols with minimal lab work. They check total testosterone, start you on a standard dose, and call it done. We run full panels with 20+ markers (including free T, SHBG, estradiol, DHT, thyroid, and metabolic markers that most clinics skip entirely), design individualized protocols, and optimize over months with follow-up labs. We are practicing medicine, not running a prescription service.
What if I've already tried TRT and didn't feel right?
This is extremely common and one of the most frequent reasons patients find us. Poor protocols, lack of estrogen management, inadequate monitoring, wrong injection frequency, missing cofactors: there are many reasons TRT can go wrong. We often find that patients who felt 'off' on TRT were either under-dosed, over-converting to estrogen, or had other untreated issues (like thyroid dysfunction) that were never addressed. We specialize in getting this right.
Do you prescribe HCG for fertility?
Yes, when indicated. Testosterone replacement can suppress sperm production. If maintaining fertility is a priority, we incorporate HCG into your protocol to keep the testes functioning. We discuss this during your intake so we can plan accordingly from the start.
How quickly will I feel results?
Most patients notice improvements in energy, mood, and libido within 2-4 weeks of starting therapy. Mental clarity tends to improve around the same timeframe. Full benefits, especially body composition changes like increased muscle mass and reduced body fat, typically develop over 3-6 months with consistent treatment and follow-up lab adjustments.
What does 'optimal' testosterone actually mean?
Most labs use a reference range of roughly 264-916 ng/dL. That range is so wide it is almost meaningless. A 35-year-old man at 280 is technically 'normal' but likely symptomatic. We use functional ranges based on peer-reviewed literature and clinical experience to identify where you personally feel and function best, which for most men is significantly higher than the bottom of the reference range.
Will I need to be on TRT for life?
TRT is typically a long-term commitment, especially if your low testosterone is age-related or primary. We are transparent about this from the start. For some younger patients, the cause may be reversible (lifestyle factors, medications, or other treatable conditions), and we investigate that possibility before starting therapy. Our goal is always the right answer for your specific situation.
What the first 90 days focus on
Weeks 2-4
- ✓Energy patterns are tracked against labs and symptoms
- ✓Sleep quality and recovery become early priorities
- ✓Mental clarity is monitored as the protocol is adjusted
- ✓Mood changes are reviewed instead of guessed at
Months 2-3
- ✓Body composition strategy is adjusted based on response
- ✓Drive and motivation are reassessed over time
- ✓Libido and sexual function are monitored clinically
- ✓Training recovery is compared with follow-up data
