Every men's health platform has an add-on menu. You're already paying for TRT or a GLP-1 — then the intake flow asks if you'd also like NAD+ injections, a B12 shot, a glutathione drip, a peptide protocol, or a "longevity panel." Each add-on runs $100–$400/month. Some are legitimate. Some are clinic-margin padding dressed in optimization language.
Here's a framework for deciding which extras justify the spend.
The Evaluation Matrix
| Add-On | Evidence Level | Typical Cost | Verdict |
|---|---|---|---|
| Vitamin B12 injection | Strong — for deficiency | $25–$50/shot | Worth it IF you're actually deficient. Most men aren't. |
| NAD+ injection | Preclinical strong; human trials early | $200–$400/mo | Experimental. Budget for it only after core therapies are optimized. |
| Glutathione injection | Minimal for healthy adults | $50–$150/shot | Skip. Oral NAC does the same job for $20/month. |
| Sermorelin | Modest clinical evidence | $150–$300/mo | Reasonable experiment if sleep/recovery are priorities. |
| BPC-157 | Preclinical only; no human trials | $100–$250/mo | Entirely experimental. No published human safety data. |
| HCG (on TRT) | Strong for testicular maintenance/fertility | $50–$100/mo | Worth it if fertility preservation is a goal. |
| Anastrozole (AI on TRT) | Guideline-supported when estradiol is elevated | $20–$50/mo | Necessary if E2 is high; harmful if used prophylactically. |
| Vitamin D injection | Strong for deficiency | $25–$75/shot | Test first. If deficient, oral D3 is cheaper and equally effective. |
The Three-Question Filter
Before adding anything to your regimen, ask:
The Add-On Decision Filter
- 1. Is there a published human trial showing this specific intervention improves outcomes in my population? "My population" means otherwise-healthy men on optimization protocols — not critically ill patients, not rodents, not athletes in extreme conditions.
- 2. Is there a cheaper alternative that achieves the same goal? Glutathione injection vs. NAC capsules. Vitamin B12 shot vs. sublingual B12. The therapeutic molecule matters; the delivery premium often doesn't.
- 3. Am I spending on this before maximizing the therapies that already work? If your TRT dose isn't optimized, your GLP-1 isn't titrated, or your sleep hygiene is terrible, adding a $200/month peptide is cosmetic — not optimization.
The Margin Reality
Men's health clinics operate on a margin structure that makes add-ons extremely attractive. The core therapy — TRT or GLP-1 — typically has thin margins due to medication cost and clinical overhead. Add-ons like B12 shots, glutathione, and NAD+ infusions are often 80%+ margin products. A $150 glutathione injection might cost the clinic $15 in materials and 5 minutes of nursing time.
This doesn't mean all add-ons are scams — some genuinely help specific patients. But the financial incentive to recommend them regardless of individual need is powerful, and patients should be aware of it.
When Add-Ons Make Genuine Sense
Some clinical scenarios where extras are genuinely appropriate:
- Documented deficiency: A blood test showing low B12, low vitamin D, or low ferritin justifies targeted supplementation. The key word is "documented" — a lab value, not a symptom guess.
- HCG for fertility preservation on TRT: If you're on TRT and want to maintain testicular size and fertility potential, HCG is evidence-based and reasonably priced.
- Aromatase inhibitor for confirmed high estradiol: If your E2 is above range on TRT and causing symptoms (gynecomastia, water retention, mood changes), anastrozole at low dose is guideline-supported.
- Sermorelin for documented sleep disruption: If sleep quality is genuinely poor despite sleep hygiene optimization, and the cost is affordable, sermorelin has a reasonable evidence basis.
The Bottom Line
Optimize the Base Before Adding the Extras
The most impactful dollar in men's health optimization is spent on getting core therapies right — proper TRT dosing with monitoring, adequate GLP-1 titration with nutrition support, and evidence-based ED management. Add-ons belong after the foundation is solid, and only when they pass the three-question filter: human evidence, no cheaper equivalent, and core therapies already maximized.
