im sorry but there's a misconception if anyone thinks any oral is good for runners... flat out not true... when you run an oral, chances are very high your getting excruciating pumps, one of the reasons no runner should ever consider anavar use if that's your main sport... winstrol was used in the 80's and 90's by sprinters to increase power and explosiveness, yes, and while more conducive to a sprinter, a long distance runner is setting themselves up for big issue with a methylated oral... winstrol obviously dries you out to a far higher degree than most, and that only adds to the probability of pain while running... you SHOULD be seeing an increase in strength, absolutely and definitely in aesthetics and muscle hardening, which at times could cause pain, but should not... the toxicity in winstrol, which is very high, can definitely cause lethargy... the ONLY issue i have ever had with winstrol is the lethargy and that is a clear indication your liver cannot handle it at that dose... you need to lower the dose to help with this... drink plenty of water, add some taurine and make sure you get enough carbs throughout the day... other than that, you should be feeling quite good with it... i often recommend MK2866 with it to combat all the drying and joint pain and GW-501516 for the damage done to your cholesterol... ive used winstrol extensively, so have a great deal of experience with it... its my favorite oral and i know a lot of things to go along with it and what to definitely expect... i find that 25mg per day is extremely effective...
