Can you advise if its normal to have low testosterone at early 30's?
Testosterone levels vary quite dramatically between individuals and to a lesser extent the time of day they are measured (up to >13% variation). The laboratory gives you the results as total testosterone and free testosterone which is bioavailable. If you have symptoms and are at the low end of the range or below the minimum 'normal' level you might wish to discuss it with your doctor or see an Endocrinologist.
Think carefully before just taking a Testosterone supplement as it also has side effects that need to be considered depending on your personal circumstances.
It depends how low and whether you have other symptoms. Some men have low testosterone and no related symptoms and it is generally not recommended that they have hormone replacement because of the risks and limited benefits.
If you have symptoms and haven't already had multiple tests this is essential. Your tests should include SHBG and Albium so that free and bioavailable testosterone can be calculated in addition to total testosterone. Your tests should be done at 8am or as close to this as can be arranged and at a time when your life is a normal as possible (e.g. not at a time of high stress or other transient medical conditions). I not a doctor but personally I would also request other HPA axis tests before making a decision about starting HRT. These include LH, FSH, GnRH, ATCH, 24h cortisol. This is especially the case if there are no obvious issues with your testicles.
If you do have significant symptoms and constantly low testosterone then HRT is probably a very good idea, at the very least on a trial basis (3-6 months). There are many related health issues for men with low testosterone and, if you follow the normal progression for most men, you levels will reduce as you get older.
Be aware though that longer term treatment is a commitment for life because you will probably lose most of your natural ability to produce the hormone. If you're basically well at the moment I'd suggest you take a wait and see approach. Monitor levels and other symptoms.
