I'm male, mid 40's, 140 Lbs, 5'8", lean and low body fat, looking to increase strength for an endurance sport. I'm planning to try Oxandrolone for 8-12 weeks (***ending on the dosage I end up using) with Nolvadex, Clomid, and Proviron for PCT. I read an article on "pulsing" by "Dr. D" at http://forum.anabolicx.com/index.php?showtopic=1773 . Sounds like something that might work for my situation. I plan on starting with 20 mg oxandrolone per day and going up to 60 mg per day as needed for 3-4 days per week. I'm considering only dosing in the AM pre workout and skipping the post workout dose because the 9 hour half life should leave plenty in my system to aid in recovery while allowing me to avoid shut down: I know that limits my gains, but I want to stay lean and gain strength only. On my off days I'd like to use an otc anti catabolic. Is phosphatidylserine an adequate choice? I could also use Tribex and GH Max on my off days to keep things rolling too. The pulsing article states that PCT wouldn't be needed after 4 weeks of pulsing. If I go 8-12 weeks would I need PCT? How could I tell? This is going to be my first cycle. I have used androstendione and prednisone in the past: I found out prednisone is catabolic and started looking for an better way. This cycle should start in the next couple of weeks. Your input is welcomed!
