I'm on day 5 with TS 17 and honestly I'm not feeling different except that I get physically tired, fast! Even if I'm just doing some yard work. I'm taking it every 6 hours or so and have adjusted my diet. I had issues with both knees as a shoulder that really knocked me on my ass, so I'm only doing cardio on a rower, push-ups and sit-ups. Really just getting into working at normal fitness. My test was 520 3 weeks ago. No supplements or anything. 42, 230 and need to drop 30 pounds. Shouldn't I be feeling the effects of TS17 by now? No increase in libido at all.
