The gym stopped working: hormones, recovery, and what to measure
A genuine training plateau in a man training 3–6 sessions per week with adequate technique and progression has three common hormonal explanations: chronic energy deficit suppressing the HPG axis (low T with low LH/FSH), undisclosed androgen or SARM exposure shutting down the axis (low T with suppressed LH/FSH and low estradiol), or a metabolic shift dropping SHBG into a range that masks T problems. A six-marker panel reads all three. Sleep, calorie intake, and programming are the non-hormonal causes that need to be ruled out at the same time.
Training hard and seeing nothing back is one of the few situations where hormones really are the highest-yield single test.
Who this page is for
Men in their 30s and 40s training consistently — three or more sessions per week, for at least 12 months — who have hit a clear, sustained plateau in strength, body composition, or recovery despite doing the right things on paper. Not for men who haven't progressed in 6 weeks; that's noise.
What's actually happening
Strength and hypertrophy run downstream of recovery, and recovery runs downstream of androgens, sleep, energy availability, and inflammation. When the HPG axis is healthy and you're eating and sleeping enough, the gym works in proportion to the work. When the axis is suppressed — by energy deficit, overtraining, undisclosed cycle use, or even just chronic high stress — testosterone falls, SHBG often shifts to compensate, recovery slows, and the same training stimulus produces measurably less adaptation. Reading T, LH, FSH and SHBG together separates 'the axis is suppressed' from 'training is wrong' faster than any other workup.
- TTestosterone
Total + free testosterone. A truly suppressed total T (well below mid-range, with morning sampling) in a trained man eating enough is a meaningful finding. Read with LH to figure out whether the cause is testicular or central.
Read the Testosterone brief → - SHBGSex hormone-binding globulin
Often the most actionable single number in this audience. SHBG that's dropping (typical with rising insulin resistance, even in lean men) inflates free T calculations and hides the real picture. SHBG climbing alongside aggressive cutting or under-eating signals an energy-deficit pattern.
Read the SHBG brief → - LHLuteinising hormone
The pituitary signal. Low LH with low T = the brain isn't sending the signal. The most common cause in this audience is energy deficit or stress; the second most common is undisclosed exogenous androgen or SARM use. The pattern reads identically; only the history distinguishes them.
Read the LH brief → - FSHFollicle-stimulating hormone
Tracks LH in this picture and is the most sensitive marker of testicular cell function. Suppressed FSH alongside suppressed LH points to a central problem; elevated FSH points to testicular compromise.
Read the FSH brief → - E2Estradiol
Runs from testosterone via aromatase. Very low E2 in a trained man with low T is the textbook signature of a fully shut-down axis (often post-cycle or under aggressive deficit). High E2 with high T can show up in higher-body-fat men and on exogenous testosterone.

What to do next
Get the panel before you change anything else in the gym. In parallel: total up your weekly calories honestly (most plateaued lifters under-report), check that you're sleeping 7+ hours, and review supplements and any non-prescription performance compounds. If the panel shows a suppressed axis without supplementation, the answer is usually energy availability and stress, not more training. If everything reads clean, the answer is programming — get a coach's eye on your training.
- !Rapid loss of muscle mass with crashing libido — axis collapse, see an endocrinologist.
- !Persistent injuries to the same connective-tissue site — sometimes T-driven, sometimes overtraining; needs medical input either way.
- !Use of any SARM, prohormone, or compound from a 'research' supplier — bring this honestly to whoever reads the panel; it changes interpretation entirely.
- !Concurrent finasteride or other 5-AR inhibitor use — interacts with this picture, mention it.
