This is the best blended testosterone product l have ever used . Within 6-8 hours you can feel the effects of it . Your libido begins to get reved up and gets kinda annoying like you are on tren ace. The strength gains and size gains are impressive and the ratios actually keep bloat at bay compared to sustanon. No PIP at all for me and 100mg prop from other sources or sustanon always give me small PIP. I gave some to a couple friends and they both said same thing 8 hours later libido going strong etc 💪
