i'm 40 with +20 years of AAS use...in my opinion the best gear for us old guys is of course GH and test.
my cylce varies but for the most part it will look like this:
GH....4 units in one shot..5 days on...i stay on G for most of the year taking very few breaks....i use it more for its immune boosting and anti-aging factors.
delatestryl enanthate (BTG)...avg.400mg per week on a 12 week cylce and 200 for a maintance dose.
btg anavar if you can afford it.
halotestin
arimidex
as you can see i only will use pharmaceutical grade gear
