This is the sixth or seventh time I’ve used this product. Always good size gains. I can tell you it’s “full strength” I’ve used other brands and not been as impressed. I will definitely be using it again this spring. I run 1000mg Test and 400mg Tren. Inject daily for consistent blood levels. Put on 10lbs or so of clean muscle this past time over an 6 week cycle. Keep Tren cycles short to keep side effects down.
