- 0:00Think of jumping on testosterone for the TRT or your first cycle.
- 0:03You've got your blood work done and you've had this
- 0:05and you haven't got a clue what you're looking at.
- 0:06Today I'm going to break it down.
- 0:07Before we do that, jump us off our own.
- 0:09So first up we've got FSH and LH.
- 0:11FSH is follicle stimulating hormone.
- 0:13That is a hormone that signals to the testes
- 0:15to produce ABP or angiotrumbinding protein.
- 0:18Lutinizing hormone, LH signals to the testes
- 0:20to produce testosterone.
- 0:22The ABP that angiotrumbinding protein binds
- 0:24to the testosterone and that creates sperm.
- 0:26So think of this as like testicular health,
- 0:28sperm or testosterone production
- 0:29coming from the balls and testes.
- 0:31The third one is estradol, estrogen,
- 0:33E2, there's various names for it.
- 0:34This is the total amount of estrogen in the body at one time.
- 0:37Serum estrogen is also known as.
- 0:39Now this is particularly like a big concern for a lot of people
- 0:42when they jump on testosterone, they need two side effects.
- 0:44It depends how much you romanticize.
- 0:46It really varies each to the individual.
- 0:48But it's always one to keep an eye on that for sure.
- 0:51Testosterone or serum testosterone,
- 0:52the amount of total testosterone in the body at one time.
- 0:55It doesn't really matter that much.
- 0:56The TRT-FEST cycle when you're looking at it
- 0:58is kind of pointless because the important one
- 1:00is the one below free testosterone.
- 1:02This is the testosterone that is not bound to proteins
- 1:04come used by the body for what we wanna use it for.
- 1:07And then lastly, prolactin, lactation,
- 1:09this signals to the breasts to produce milk.
- 1:12High prolactin often associated with
- 1:14the beta issues erectile dysfunction.
- 1:16Using exogenous testosterone, FSH and LH will be in the bin.
- 1:19Estrogen will depend on how much you romanticize.
- 1:22Testosterone will depend on how receptive
- 1:24the same as with free testosterone.
- 1:26Pro-lactin, same again, mainly lifestyle choices though.
Reading a hormone panel: what TRT influencers get right and wrong
Quick answer
Hormone panels for TRT monitoring typically include total and free testosterone, estradiol (E2), FSH, LH, prolactin, hematocrit, PSA, and a metabolic panel. Gonadotropin suppression (low FSH/LH) is an expected and clinically significant consequence of exogenous androgen use, reflecting negative feedback on the hypothalamic-pituitary-gonadal axis. Free testosterone is the biologically active fraction, but total testosterone remains a standard marker for dose adequacy and should not be dismissed as irrelevant.

Page-specific review note
What this exact clip is really saying
This FormBlends review is specific to "Reading a hormone panel: what TRT influencers get right and wrong" from Modern Man Clinic. We read the clip as a TRT social video fact-checks claim about Testosterone, then separate the useful signal from what a short social video cannot prove. The page-specific claim focus is: Hormone panels for TRT monitoring typically include total and free testosterone, estradiol (E2), FSH, LH, prolactin, hematocrit, PSA, and a metabolic panel.
The reason this review is not generic is the source wording and the canonical claim label "trt how to read your hormone panel a lot of dudes send me this c." In this clip, the useful excerpt is: "Think of jumping on testosterone for the TRT or your first cycle." That wording changes the review because it points to Testosterone evidence, safety, and patient-fit context, not a one-size-fits-all protocol.
The source trail for this page is checked against Cardiovascular Safety of Testosterone-Replacement Therapy (2023), Testosterone therapy in men with androgen deficiency syndromes: an Endocrine Society clinical practice guideline (2010), and Functional testosterone deficiency in aging men: Clinical impact, diagnostic pathways, and treatment strategies (2026), plus the creator's own wording. Testosterone decisions still need an eligibility review, medication-interaction screen, access check, and quality-control review before anyone treats a social clip as medical advice.

What it helps with
- Hormone panels for TRT monitoring typically include total and free testosterone, estradiol (E2), FSH, LH, prolactin, hematocrit, PSA, and a metabolic panel. Gonadotropin suppression (low FSH/LH) is an expected and clinically significant consequence of exogenous androgen use, reflecting negative feedback on the hypothalamic-pituitary-gonadal axis. Free testosterone is the biologically active fraction, but total testosterone remains a standard marker for dose adequacy and should not be dismissed as irrelevant.
- FSH and LH suppression is an expected and well-documented consequence of exogenous testosterone use, not a sign something has gone wrong. Bhasin et al. (2010, NEJM) confirm this as a predictable pharmacological effect.
- ABP (androgen-binding protein) concentrates androgens in the testes to support sperm development, but it does not itself produce sperm. The video's explanation of this mechanism is inaccurate.
What it may miss
- It may not cover eligibility, contraindications, medication interactions, lab history, or dose escalation.
- Compound access, legal status, and product quality still need a separate safety check.
- Social video captions rarely show the full evidence base behind a claim.
Best next step
Compare the claim against a FormBlends guide, safety page, and licensed-provider review before acting.

Our take · Written by FormBlends editorial team · Reviewed by FormBlends Medical Team · This is not a transcript. It is our independent review of the video above.
What did @harveylonsdale_ actually say?
The creator walks viewers through a standard hormone panel, covering FSH, LH, estradiol, total testosterone, free testosterone, and prolactin. The framing is aimed at guys starting TRT or their "first cycle" who receive lab results and have no idea what they mean. Fair enough, that's a real gap. He explains that LH signals testosterone production, FSH triggers androgen-binding protein (ABP) production, and that ABP binding to testosterone creates sperm. He then notes that on exogenous testosterone, FSH and LH will "be in the bin," and that estrogen and prolactin levels depend on individual factors and lifestyle. He correctly separates total from free testosterone, calling total testosterone "kind of pointless" on TRT.
The intent is educational and the delivery is casual. But several of the biological claims underneath the plain-English packaging have real accuracy problems worth unpacking.
Does the science back this up?
Partially. The FSH/LH suppression point is solid. The ABP-sperm claim is where things fall apart, and calling total testosterone "pointless" on TRT is an oversimplification that could mislead people managing their health. The prolactin section is vague to the point of being nearly useless.
On suppression: exogenous testosterone reliably suppresses gonadotropins through negative feedback on the hypothalamic-pituitary axis. This is textbook endocrinology and is well-supported by clinical data, including the landmark hypogonadism trials summarized by Bhasin et al. (2010, New England Journal of Medicine). Expect FSH and LH to drop significantly on TRT. That part is accurate.
On estrogen: the video says levels "depend on how much you aromatize," which is roughly correct. Testosterone converts to estradiol via the enzyme aromatase, with conversion rates varying by body composition, genetics, and dose. Camacho et al. (2013, Journal of Clinical Endocrinology and Metabolism) confirmed that higher adiposity increases aromatase activity, which is why estrogen management is not one-size-fits-all.
What did they get wrong (or right)?
The ABP explanation is where the science goes off track. The creator says FSH stimulates ABP production, that ABP binds testosterone, and that this "creates sperm." This conflates several separate processes. ABP (androgen-binding protein) is produced by Sertoli cells in response to FSH and serves to concentrate androgens locally within the testes to support spermatogenesis. It does not create sperm. Sperm production is a multi-step process requiring FSH, testosterone, and functional Sertoli and Leydig cells. ABP is a facilitator, not a factory. Calling total testosterone "kind of pointless" on TRT is also too strong. While free testosterone is the biologically active fraction, total testosterone remains a useful clinical marker, especially when tracking dose adequacy, conversion rates, and for comparing against population reference ranges. Petak et al. (2002, Endocrine Practice) recommend monitoring both.
What he got right: the free testosterone distinction is genuinely important and under-discussed. The point that prolactin elevation can contribute to erectile dysfunction is supported by clinical literature, including Corona et al. (2012, Journal of Sexual Medicine).
What should you actually know?
If you're reading a hormone panel on TRT, here's what actually matters. FSH and LH dropping toward zero is expected, not alarming. It reflects suppression of the HPG axis. Estradiol monitoring is legitimate but the threshold for concern is individual. The idea that all estrogen is bad is a persistent myth in TRT communities with no serious clinical backing. Symptoms matter more than a single number. Free testosterone is the more functionally relevant metric, but your clinician will still track total testosterone for the full picture. Do not bin that number.
Prolactin elevation can come from several sources: pituitary adenomas, certain medications (antipsychotics, antiemetics), sleep deprivation, and stress. Lifestyle plays a role, but attributing high prolactin purely to "lifestyle choices" without ruling out pathology is premature. Anyone with consistently elevated prolactin should get imaging discussed with their doctor. If you're managing your hormone health on TikTok tutorials alone, that is a problem this video can't solve.
