1-3 months: Raising one's testosterone level has effects throughout the body. The endocrinologist who is prescribing the testosterone will have the most accurate answer to "how long before a patient notices improvement". Probably the improvements in mood and sexual interest will come first, maybe in a month. The changes in skin, hair, penis, testicles, muscles, blood, etc., will probably come in 3 months.

Pretty soon: Usually does not take long but we like to start the treatment slowly mimic normal pubertal development that in a boy can take 2-4 years.

Depends on levels: I usually see improvement by the second or third injection and that tends to correlate largely on serum levels. Depot injection tend to have peak/trough effect versus gels which provide a more "physiological" absorption rate, however my experience with gels in teen age boys have disappointing to say the least ! (added the risk of skin transmission to other children).

Depends!: Time for effects of testosterone replacement to be noticeable depend upon route/dose, effect & you! most branded t can make subjective improvements in mood, thinking, sex drive (libido) & erectile function in days if given in an adequate dose.

1 week -- 6 weeks: Depending on the route (cream, injections, or testosterone pellets), some men can experience an increase in their energy, improvements in their sleep, and changes in their mood, concentration, and focus as early as one week. For others, it may take as much as 6 weeks to reach peak hormone levels and peak response rates.

Depends: Testosterone replacement is done in many different forms for men and at different starting points. How quickly a man will feel a difference depends on the type of replacement used and his baseline. In general most men feel a difference within 4-8 weeks. If you do not, you need your levels checked anyways at 3months but do it sooner to adjust your medication.
