I would lean away from sourcing, for the moment. How ever I will fill you in on my experience with this particular SARM. GW, is a great product for just what serotonin said it is for, endurance. It is currently in phase II medical trials with the FDA, fro use in treating a number of things, including high blood pressure and loss of bone mass in older men and women. From my personal experience you can expect to get a nice boost to over all recovery time between sets, and days of heavy exercise. You are not going to see a big boost to lean mass, what you will get is a nice solid boost in fat loss, a favorable shift in lipid profiles as well as keeping your blood pressure in check, and even lowering it in some cases ( my dad was one of these cases after a 90 day cycle of it his BP increases again , but while on it his BP was better then when he was taking medication for it.)
I run myself, five miles every day I went from 50mins to 37:30 at current for 5 miles and fro me I am limited due to knee injuries. But after the run I am still fresh enough to do my yoga, and hit the gym. GW is best used with a cutting diet or a recomp, where the focus is going to be on the loss of body fat % with the preservation of muscle mass. Now what are your stats, height, weight, body fat % and training history.teh cancer risk was largely in mice, while at points comparable to humans fro the purpose of medical testing the comparison is nto always as good as you are led to believe, the WADA issues the cancer warning, due to mouse testing, but the amount of GW and time frame, would be the issue not the proper short term cycling of the compound at reasonable dosages 5-30mg daily. Though I would not go beyond 20mg/daily and no longer then 90 days, though you can push it to 120 days, I would advise staying at 90/days or less. It is pricy but so is any thing of high quality.
What are your intentions for the GW and the Telmisartan ?
