Question 1

How is testosterone cypionate different from other forms of testosterone?

Accepted Answer

Cypionate is a long-acting injectable ester — the most prescribed form of TRT in the US. It produces a peak at 48–72 hours after injection and a trough at the end of the week, which is why many providers split the weekly dose into twice-weekly to smooth out the curve. Alternatives include enanthate (very similar half-life), undecanoate (much longer-acting, given every 8–10 weeks), oral options like Kyzatrex or JATENZO, and topical gels. Cypionate is the default because it is effective, cheap, well-studied, and easy to dose-titrate.

Question 2

How quickly will I feel results?

Accepted Answer

Most men report improved energy and libido within 3–6 weeks. Mood usually shifts in the same window. Body composition changes (more muscle, less fat) accumulate over 3–6 months and depend heavily on training and nutrition alongside the therapy. If you do not notice any change by 12 weeks at a properly titrated dose, your provider should re-evaluate. The number on the lab matters, but symptoms matter more — TRT is dosed to how you feel, not to a target value.

Question 3

Will testosterone therapy affect my fertility?

Accepted Answer

Yes. Exogenous testosterone signals the brain to stop producing LH and FSH, which shuts down endogenous testicular function — including sperm production. Most men on TRT become functionally infertile within 3–6 months. If you may want to conceive in the future, talk to your provider before starting. HCG can be added to preserve testicular function during TRT, or HCG-only / clomiphene protocols can raise endogenous testosterone without suppressing fertility. Banking sperm before starting TRT is also worth considering.

Question 4

What labs do I need before starting?

Accepted Answer

At minimum: two morning total testosterone measurements on separate days, free testosterone, SHBG, LH, FSH, prolactin, estradiol (sensitive assay), CBC, CMP, lipid panel, and PSA. Many providers add a fasting glucose or HbA1c, plus thyroid panel, depending on the clinical picture. The point is twofold: confirm the diagnosis (one low number is not enough) and establish baselines for hematocrit, lipids, and PSA so you can track changes over time on therapy.

Question 5

Is there a risk of prostate cancer?

Accepted Answer

TRT does not cause prostate cancer. Decades of data — including the recent TRAVERSE trial — show no increased incidence in men on therapy. However, TRT can accelerate the growth of pre-existing prostate cancer, which is why baseline PSA and a digital rectal exam are part of the standard workup, and PSA is monitored quarterly thereafter. If your PSA rises significantly after starting TRT, your provider should pause therapy and refer for urology evaluation. The protocol is standardized and the risk is well-managed when monitored properly.
