I started my TRT in my early forties . I can tell you 200mg Test C was prescribed dosage . I was also prescribed .5 Armidex EOD . 500iu HCG/week . This was clinic that charged $195/month W/O meds or testing .
This gave me Test levels equal to a 20 year old man . I tried Sustanon and added mass . Might have been the 50mg extra Test , Sustanon only come in 250mg and I couldn't waste .2 ml .
In your situation I would recommend Sustanon @ .8/week . That is 200mg .
Goodluck in the Ironman contest
