For a 37yrl running a Testosterone only cycle, the way I would run mines is as follows:
week 1-8
Testosterone Enathate injections 500mg per week.
Hcgenerate 2 caps per day
Liquidex AI 2cc-3cc per day
OPTIONAL for old guys like me over 35yrl:
Cardarine 10mg ED
Ostarine 25mg ED
week 9-10
Hcgenerate 5 caps per day
Liquidex AI 2cc per day
PCT:
Week 11-18
Hcgenerate 5 caps per day
Clomid (50mg week 11-12 - 25mg week 13-18)
Liquidex AI (1cc per day weeks 11-14 drop to 0.5cc weeks 15-18)
D-Aspartic Acid 3g per day
Post PCT:
D-Aspartic Acid 3g per day

That is just the way I would run it. At my age I find Osta and GW to just gives me more energy and feel I recover great on it. It is the part of the cycle that to me makes me feel like a dude in my 20's again.
