TRT doses vs bodybuilding doses: what the data actually shows

What did @suppsreviewsuk actually say?

The creator argues that a beginner dose of testosterone sits between 200 and 300 milligrams per week, and uses TRT as the reference point, noting that "a TRT dosage of testosterone is sometimes 1cc... usually about 200 milligrams per week." They also claim Greg Doucette uses less than a standard TRT dose, and finish by saying they personally got "amazing results" on 250mg via Sustanon 250. The implicit argument is that 300mg is modest and reasonable for a newcomer to anabolic use.

This framing is doing a lot of work. Blending TRT language with bodybuilding-dose justification is a rhetorical move worth examining carefully, because the two contexts are not the same thing and conflating them obscures real clinical risk.

Does the science back this up?

No, not really. Legitimate TRT sits far below what this video calls a beginner dose, and calling 300mg per week modest is not supported by the endocrinology literature.

Clinical guidelines from the Endocrine Society (Bhasin et al., 2018, Journal of Clinical Endocrinology and Metabolism) define TRT targets as restoring serum testosterone to the mid-normal physiological range, roughly 400 to 700 ng/dL. Standard injectable TRT protocols typically use 50 to 100mg of testosterone cypionate or enanthate per week, or 100mg every two weeks in some older protocols. Some patients on the higher end of clinical dosing reach 200mg per week under supervision, but that is not the norm and is typically reserved for patients with persistently low levels or poor absorption.

A 2021 review by Rastrelli et al. in Therapeutic Advances in Endocrinology and Metabolism confirmed that supraphysiological dosing, which begins around 200 to 300mg per week for most men, produces testosterone levels well above the normal male range and carries dose-dependent risks including erythrocytosis, suppression of the hypothalamic-pituitary-gonadal axis, and adverse lipid changes. The creator is describing a supraphysiological dose and calling it a beginner protocol.

What did they get wrong (or right)?

They got the TRT reference range partially right. Yes, 200mg per week is sometimes prescribed in clinical settings, though it is on the upper edge of standard protocols. Credit where it is due: they did not recommend 500 to 600mg, and they pushed back on that figure. That is a reasonable position.

But several things are clearly wrong. First, using TRT dosing as justification for a bodybuilding beginner dose conflates two entirely different goals. TRT replaces a hormone deficiency. A 300mg-per-week cycle in a healthy young person with normal testosterone levels is not replacement, it is supraphysiological supplementation with known risks. Second, the anecdote about personal results on 250mg of Sustanon 250 is not evidence of safety or appropriate dosing. Sustanon 250 contains a blend of four testosterone esters, which creates a different pharmacokinetic profile than testosterone enanthate alone, a distinction the creator blurs. Third, citing what Greg Doucette allegedly uses is not a clinical argument. It is a social proof fallacy.

What should you actually know?

Testosterone at any dose above what your body naturally produces is a controlled substance in the UK and a Schedule III substance in the US. There is no such thing as a medically appropriate "beginner dose" for someone without a diagnosed deficiency. If you have low testosterone confirmed by blood work and assessed by a licensed clinician, TRT under medical supervision is a legitimate option. If you are a healthy person looking to enhance athletic performance, no dose is medically endorsed for that purpose.

The risks at 300mg per week are real and documented. They include testicular atrophy, suppression of natural testosterone production, elevated hematocrit, changes in cholesterol profiles, and mood disturbances. A 2019 study by Skinner et al. in the British Journal of Sports Medicine found that supraphysiological testosterone use was associated with persistent hypogonadism after cessation, sometimes lasting years. The framing of 300mg as conservative does not hold up against that evidence. Anyone considering testosterone use should do so only under qualified medical supervision with full bloodwork and informed consent.
