HRT = hormone replacement therapy (or TRT = testosterone replacement therapy in his case) means to supplement with exogenous testosterone (synthetic) to replace his endogenous (normal production in the body) testosterone in case he's not producing enough anymore due to aging or steroid abuse or sometimes an accident that damages his testicles or a disease that affects his production.
HCG = human chorionic gonadotropin , which acts like LH (Leutenizing Hormone) a hormone that stimulate the testes to produce testosterone, and can maintain testicular volume while on hrt or cylcing with AAS (anabolic androgenic steroids)
1 jab 2 ml ??? dunno could be anything , maybe it's testosterone but can't estimate the exact dosage, usually long esters testosterone ( which means they stay long in the system) like testosterone enanthate and testosterone cypionate can be injected once a week for HRT and usually comes in 200-250 mg per ml
where as testosterone propionate (short ester or fast acting and leave the system faster than the previous mentioned) comes in 2ml amps of 100mg (50mg per 1 ml) and should be administered at least twice a week.
hope that helps a bit
excellent post
