Key Takeaways

  • Legitimate online testosterone therapy requires two confirmed early-morning total testosterone readings below 300 ng/dL, plus symptoms (Bhasin et al., Endocrine Society 2018).
  • Most online programs use injectable testosterone cypionate at 100 to 200 mg weekly, sometimes paired with hCG and an aromatase inhibitor.
  • Expect monthly costs of $99 to $250 including labs, follow-up, and medication.
  • Required monitoring includes baseline and follow-up total testosterone, hematocrit, PSA, lipid panel, and estradiol every 3 to 6 months in year one.
  • A program that prescribes without lab confirmation, doesn't monitor hematocrit, or skips PSA in older men is not following the standard of care.

Direct answer (40-60 words, snippet-optimized)

Online testosterone therapy is a telehealth-delivered treatment for clinically diagnosed hypogonadism. A licensed provider reviews labs and symptoms, prescribes testosterone (usually injectable cypionate), and monitors response with quarterly bloodwork. Real programs require two morning testosterone readings under 300 ng/dL plus symptoms. Programs that skip diagnostic labs are not practicing within the standard of care.

Who actually qualifies for testosterone therapy

The diagnosis of male hypogonadism requires both:

Gonadorelin (GnRH)

From the FormBlends catalog

Gonadorelin (GnRH)

  1. Symptoms consistent with low testosterone (low libido, erectile dysfunction, decreased morning erections, depressed mood, fatigue, decreased muscle mass, increased body fat, decreased bone mineral density), and
  2. Two separate morning serum total testosterone measurements below 300 ng/dL, drawn between 7 and 10 AM on different days, with symptoms present.

The Endocrine Society's 2018 guideline (Bhasin et al., J Clin Endocrinol Metab 2018) is the document most providers reference. The American Urological Association's 2018 testosterone deficiency guideline uses the same 300 ng/dL threshold and the same "two confirmed lows" rule.

Some men in the 300 to 400 ng/dL range have free-testosterone deficits that don't show up on total testosterone alone. SHBG (sex hormone binding globulin) needs to be measured to calculate free testosterone. Free testosterone below 6.5 ng/dL with classic symptoms can warrant treatment even with normal total testosterone.

Symptoms alone do not justify TRT. Many low-T symptoms overlap with depression, sleep apnea, hypothyroidism, anemia, and chronic fatigue. A workup that doesn't rule out these alternatives isn't a workup.

Men who shouldn't start TRT through any clinic, online or in-person:

  • Active or untreated prostate cancer
  • Active breast cancer
  • Severe untreated sleep apnea
  • Hematocrit above 54%
  • Severe untreated congestive heart failure
  • Men actively trying to conceive (TRT suppresses sperm production)
  • Untreated severe lower urinary tract symptoms

The lab work that legitimate programs require

A reputable online TRT clinic will require the following labs before prescribing:

Initial baseline panel:

  • Total testosterone (morning, between 7 and 10 AM)
  • Free testosterone (calculated or measured directly)
  • SHBG
  • LH and FSH (to distinguish primary from secondary hypogonadism)
  • Prolactin (rules out pituitary tumors)
  • Estradiol (sensitive assay, not routine)
  • Complete blood count (especially hematocrit)
  • Metabolic panel (CMP)
  • PSA (men over 40, or younger with family history)
  • Lipid panel
  • Hemoglobin A1C
  • TSH

The rationale: testosterone is downstream of multiple endocrine systems. Treating "low T" without checking LH/FSH, prolactin, and TSH risks missing a pituitary tumor, primary testicular failure pattern, or thyroid disease that's actually driving symptoms.

Repeat lab confirmation. A second early-morning total testosterone reading below 300 ng/dL should be done on a different day before treatment starts. Diurnal variation in testosterone is real, and a single low reading can be a circadian artifact rather than true hypogonadism.

A clinic that prescribes off a single saliva test, a self-reported symptom score, or no labs at all is not following the standard of care. They may still ship medication, but the prescription isn't on a defensible clinical foundation.

How online TRT visits work

The general flow at a legitimate telehealth TRT program:

  1. Intake questionnaire. Detailed medical history, current symptoms, fertility plans, family history of prostate or breast cancer, sleep apnea screening.
  2. Lab order. The clinic sends an order to a partner lab (LabCorp or Quest most often). The patient walks into a draw center.
  3. Provider review. A licensed clinician (MD, DO, NP, or PA, depending on state scope) reviews labs and history. If the patient meets diagnostic criteria, a video or phone visit is scheduled.
  4. Diagnostic visit. The provider confirms the diagnosis, discusses treatment options, reviews risks, and addresses fertility concerns. Informed consent is documented.
  5. Prescription. Medication ships from a state-licensed pharmacy. Most programs use a 503A or 503B compounding pharmacy or a retail pharmacy depending on the formulation.
  6. Follow-up visits. Initial follow-up labs at 6 to 8 weeks, then quarterly during year one, then twice yearly thereafter.

State law varies. Some states require a video visit for the initial prescription; others allow asynchronous review based on labs and questionnaire. The DEA reclassified testosterone scheduling rules years ago, but states still set their own telemedicine requirements.

Forms of testosterone used in telehealth

FormTypical doseFrequencyProsCons
Testosterone cypionate (injection)100-200 mgWeekly or twice weeklyCheap, predictable levels, decades of dataNeeds injections
Testosterone enanthate (injection)100-200 mgWeeklySimilar to cypionateSlightly shorter half-life
Testosterone propionate (injection)50-100 mgEvery 2-3 daysStable levelsFrequent injections
Topical gel (1% or 1.62%)25-50 mg/dayDailyNo needlesSkin transfer risk, variable absorption
Subcutaneous pellet1,200-2,000 mgEvery 3-6 monthsSet-and-forgetOffice implant, can extrude
Transdermal patch4 mg/dayDailySteady levelsSkin irritation common
Buccal/oral testosterone30 mgTwice dailyNo injectionsGum irritation, expensive

Most online programs default to weekly or twice-weekly subcutaneous testosterone cypionate at 100 to 200 mg per week. Twice-weekly or even three-times-weekly dosing produces flatter peaks and troughs and is increasingly preferred for stable mood and energy. Subcutaneous injection (rather than intramuscular) is now common, as multiple studies have shown comparable efficacy with smaller needles and less discomfort (Spratt et al., J Clin Endocrinol Metab 2017).

Some programs include adjuncts:

  • Human chorionic gonadotropin (hCG) at 250 to 500 IU twice or three times weekly to preserve testicular size and partial fertility.
  • Anastrozole at 0.25 to 0.5 mg once or twice weekly to suppress estradiol if it climbs above the upper limit of normal during therapy. Routine anastrozole use is no longer recommended without confirmed elevated estradiol and symptoms.
  • Enclomiphene as an alternative for men trying to preserve fertility, since it raises endogenous testosterone via the HPG axis rather than replacing exogenously.

Costs of online testosterone therapy

Cash-pay TRT pricing has compressed in the past 3 years as competition has grown. Typical ranges:

ServiceMonthly costWhat's included
Initial labs$100-$300 (one-time)Full baseline panel
Provider visit$0-$199 (often bundled)Initial diagnostic
Injectable testosterone$40-$12010 mL vial of cypionate
Compounded testosterone with adjuncts$99-$200Cypionate + hCG + anastrozole
Topical gel (compounded)$80-$15030-day supply
Quarterly follow-up labs$80-$200Total T, hematocrit, PSA, estradiol
All-inclusive monthly subscription$129-$299Medication, labs, visits

Insurance covers FDA-approved testosterone preparations for confirmed hypogonadism, but the requirement for two confirmed lab lows and documented symptoms is strict. Many men opt for cash-pay because the convenience and cycle time matter more than the savings.

Compounded testosterone (made by 503A or 503B pharmacies) is sometimes cheaper than brand-name AndroGel, but it's prepared in response to an individual prescription and isn't FDA-approved. The legal framework here is similar to compounded GLP-1 medications.

Required monitoring on TRT

The schedule below mirrors Endocrine Society and American Urological Association recommendations.

Baseline (before starting):

  • Total testosterone (x2)
  • Free testosterone, SHBG
  • LH, FSH, prolactin, TSH
  • CBC (hematocrit)
  • CMP
  • PSA (men over 40)
  • Lipid panel
  • Estradiol (sensitive assay)
  • Hemoglobin A1C

6 to 8 weeks after starting:

  • Total testosterone (trough level if injecting weekly, drawn the day before next dose)
  • Hematocrit
  • Estradiol
  • PSA if elevated at baseline

Every 3 months in year one:

  • Total testosterone
  • Hematocrit
  • Estradiol if symptomatic
  • PSA in men over 40

Twice yearly after year one:

  • Same panel
  • DRE (digital rectal exam) annually for men over 40, in person when possible

Specific stop conditions:

  • Hematocrit above 54%: hold therapy until normalized; consider therapeutic phlebotomy
  • New diagnosis of prostate cancer: discontinue
  • PSA rise of more than 1.4 ng/mL in 12 months: urology referral
  • Cardiovascular event: pause and consult cardiology

A program that doesn't check hematocrit at all is missing the most common dose-limiting side effect of TRT.

Side effects and risks

Common (manageable):

  • Erythrocytosis (high hematocrit). The single most predictable TRT side effect. Roughly 6 to 25% of men on therapeutic TRT develop hematocrit above 52%. Lower with topical gels, higher with weekly injections. Risk rises with smoking and sleep apnea. Therapeutic phlebotomy or dose reduction resolves it.
  • Acne, oily skin. Especially during initial dose finding. Usually mild, settles within weeks.
  • Mild fluid retention. Occasional. More common at higher doses.
  • Increased appetite. Real but usually manageable.
  • Estradiol rise. Some testosterone aromatizes to estradiol. Mild rises are normal and often beneficial. Symptoms of high estradiol (gynecomastia, water retention, mood changes) are uncommon but worth flagging.

Less common but serious:

  • Sleep apnea worsening. TRT can exacerbate undiagnosed or undertreated sleep apnea. Screen with STOP-BANG questionnaire at baseline.
  • Cardiovascular concerns. Older observational data raised concerns. The TRAVERSE trial (Lincoff et al., NEJM 2023) of 5,246 men aged 45 to 80 showed no increased risk of major adverse cardiovascular events vs placebo over 22 months.
  • Prostate effects. TRT does not cause prostate cancer per current evidence. It can accelerate growth of pre-existing prostate cancer, which is why the diagnostic workup matters.
  • Fertility suppression. Exogenous testosterone suppresses LH and FSH, which suppresses sperm production. Most men become functionally azoospermic within 4 to 6 months of starting TRT. See the fertility section below.

Rare:

  • Thrombotic events (DVT, PE). Possible association in men with underlying thrombophilia.
  • Severe mood changes. More commonly seen in men with prior mood disorders.

Red flags for evaluating an online TRT clinic

Use this checklist when picking a program:

Green flags:

  • Requires labs before prescribing
  • Requires two morning testosterone readings below 300 ng/dL
  • Includes LH, FSH, prolactin, TSH in baseline panel
  • Monitors hematocrit and PSA on schedule
  • Provides estradiol monitoring
  • Offers fertility counseling
  • Accepts patients across all 50 states only after state-specific licensure verification
  • Discloses provider names and credentials
  • Uses licensed compounding or retail pharmacies (state board listed)
  • Allows you to take labs anywhere (LabCorp, Quest, hospital lab)

Red flags:

  • Prescribes without baseline labs
  • Uses saliva tests as primary diagnostic
  • Treats men with total testosterone above 400 ng/dL routinely
  • Pushes anastrozole or other adjuncts on every patient regardless of estradiol
  • Doesn't discuss fertility implications
  • No mention of hematocrit monitoring
  • Offers anabolic steroid stacks (Trenbolone, Anavar, Deca, Dianabol) under any branding
  • No state-by-state licensure listed
  • No published provider names

The anabolic steroid stack issue is worth singling out. Some clinics blur the line between TRT and bodybuilding-style anabolic steroid prescribing. Real TRT aims to restore testosterone levels into the mid-normal range (500 to 900 ng/dL trough). Programs targeting 1,200+ ng/dL or stacking multiple androgens are operating outside the standard of care.

TRT and fertility: what to know before starting

Exogenous testosterone shuts down the hypothalamic-pituitary-gonadal axis. The brain stops sending LH and FSH to the testes because circulating testosterone is already adequate. Without LH stimulation, the Leydig cells stop producing endogenous testosterone, and without FSH, sperm production drops sharply.

Practical implications:

  • 4 to 6 months of TRT typically produces functional azoospermia in most men.
  • Sperm production usually recovers 6 to 12 months after stopping TRT, but recovery isn't guaranteed.
  • Men actively trying to conceive should not start standard TRT.

Alternatives for men with low T who want to preserve fertility:

  • Clomiphene citrate off-label, 25 to 50 mg every other day, raises endogenous testosterone via the HPG axis.
  • Enclomiphene (an isomer of clomiphene), similar mechanism, fewer estrogenic side effects.
  • hCG monotherapy at 1,500 to 3,000 IU twice weekly, mimics LH and stimulates testicular testosterone production.
  • Combined TRT plus hCG, where hCG preserves testicular function during exogenous testosterone treatment.

Sperm banking before starting TRT is reasonable for any man under 45 without completed family planning. The cost is modest ($300 to $700 for collection and 1 year of storage) compared with future fertility treatment costs if needed.

FAQ

What labs do I need for online testosterone therapy? A baseline panel including total and free testosterone, SHBG, LH, FSH, prolactin, TSH, estradiol, CBC, CMP, lipid panel, A1C, and PSA in men over 40. Two morning total testosterone readings below 300 ng/dL on different days are required for diagnosis.

How much does online TRT cost per month? Typical all-inclusive subscriptions range from $129 to $299 per month, including medication, provider visits, and quarterly labs. Standalone medication runs $40 to $120 monthly for injectable testosterone cypionate. Initial baseline labs are $100 to $300.

Is online testosterone therapy legal? Yes, when prescribed by a provider licensed in your state after a legitimate evaluation. Testosterone is a Schedule III controlled substance, so prescribing rules are stricter than non-scheduled medications. Reputable programs verify state licensure and require labs before prescribing.

How long does it take to feel results from TRT? Energy and libido often improve within 3 to 4 weeks. Mood and concentration improvements take 6 to 12 weeks. Body composition changes (more muscle, less fat) develop over 3 to 6 months. Bone density gains take 12+ months.

Will TRT make me infertile? Standard TRT suppresses sperm production within 4 to 6 months. Most men become functionally azoospermic. Recovery after stopping takes 6 to 12 months and isn't guaranteed. Men trying to conceive should consider clomiphene, enclomiphene, hCG monotherapy, or sperm banking before starting.

Do I need anastrozole with TRT? Most men don't. Routine anastrozole prescribing has fallen out of favor. Modern guidance is to monitor estradiol with a sensitive assay and treat only if estradiol rises significantly above the upper limit of normal AND the patient has symptoms of high estrogen (gynecomastia, water retention, mood changes).

What's the difference between injectable and topical testosterone? Injectable testosterone (usually cypionate) gives more predictable blood levels at lower cost but requires regular injections. Topical gels are needle-free but have variable absorption (50 to 70%), risk of transfer to family members, and higher cost. Most clinical programs default to injectable.

Can I get TRT if my testosterone is 350 ng/dL? Possibly, if symptoms are severe, free testosterone is low, and other causes have been ruled out. The 300 ng/dL threshold is a guideline, not an absolute cutoff. SHBG abnormalities can mean total testosterone in the 300 to 400 range still produces functional deficiency.

How often do I need follow-up labs on TRT? Initial follow-up at 6 to 8 weeks after starting. Every 3 months during year one. Twice yearly thereafter. Critical labs are total testosterone, hematocrit, estradiol, and PSA in older men.

What's the difference between TRT and bodybuilding steroids? TRT aims to restore physiologic testosterone (500 to 900 ng/dL). Bodybuilding-style anabolic use targets supraphysiologic levels (1,500+ ng/dL), often stacking multiple androgens. The risk profiles diverge sharply. Programs offering anabolic stacks are not practicing TRT.

Is enclomiphene a substitute for testosterone? Sort of. Enclomiphene raises endogenous testosterone by blocking estrogen feedback at the hypothalamus, increasing LH and FSH. It works for secondary hypogonadism with intact testicular function. It doesn't help with primary testicular failure. It preserves fertility in a way exogenous testosterone doesn't.

Will TRT cause prostate cancer? Current evidence does not support TRT causing prostate cancer. The historical fear came from the observation that prostate cancer is androgen-driven, but treating eugonadal men with TRT doesn't appear to increase incidence per the Prostate Cancer Prevention Trial follow-up data and other registries. TRT is contraindicated in men with active prostate cancer.
