Low testosterone isn’t just an older man’s problem. We regularly see men in their 30s and 40s struggling with low T — and the signs go well beyond the bedroom.
You might have low T if you’re experiencing:
- Low mood, anxiety, or lost motivation
- Fatigue and brain fog
- Difficulty building muscle or shedding body fat
- Poor sleep
- Erectile or orgasm issues
- Low sperm count
What’s Causing Your Low T?
Age is the most common culprit, but it’s far from the only one. Insulin resistance, diabetes, and obesity are major drivers of low T, particularly in younger men.
Depending on your situation, we might also assess:
- Thyroid function
- Blood sugar and insulin levels
- Key nutrient levels
- Cardiometabolic markers
Working with B12 LOVE Functional Medicine Providers means getting to the root cause of your low testosterone levels. Getting to the root cause means we can do more than just replace your T — we can genuinely optimize your energy, mood, body composition, and long-term health.
Fertility First? We’ve Got Options.
Testosterone replacement isn’t suitable for everyone. Exogenous T can suppress sperm production, so if fertility is a priority, we take a different approach.
Our fertility-friendly options include:
- RevolutionPRO — our maca-based supplement specifically formulated to support natural T levels without impacting fertility. RevolutionPRO is available at all B12 LOVE locations. Find a location near you or shop it on our online Fullscript store.
- Clomid — a proven option to boost T while preserving sperm production. Only available via prescription from a B12 LOVE Functional Medicine Provider. Schedule a Functional Medicine Consultation to see if Clomid is right for you.
How B12 LOVE Delivers Testosterone
We offer flexible treatment options to fit your lifestyle:
- In-office injections
- Self-injection prescriptions for home use
- Topical forms (gels/creams)
What We Monitor — and Why It Matters
We won’t just prescribe then disappear. B12 LOVE puts your care, health, and safety first — that’s why our prescribing providers will be by your side every step of the way throughout your journey with Testosterone Therapy. We test at baseline and monitor key markers throughout your treatment to keep you optimized and safe.
| Marker | Why We Check It |
| Free & Total Testosterone | Confirms your levels and guides dosing |
| DHT (Dihydrotestosterone) | A potent T metabolite — too high can mean acne, hair loss, or prostate issues |
| Estradiol | T can convert to estrogen, especially in higher body fat — elevated estrogen causes fatigue and breast tissue growth |
| CBC (Complete Blood Count) | T stimulates red blood cell production — too many increases clotting risk; we manage this with blood donation or therapeutic phlebotomy if needed |
| PSA | Prostate health surveillance |
We fine-tune in the first six months with 2 to 3 lab checks, then transition to 1 to 2 times per year once you’re dialed in.
Not Sure If Low T Is Causing Your Symptoms?
