Hey, I know what you mean, man. I had the same thing around age 36—workouts got tough, but I wasn't making any progress. Then I switched to IGF-1 LR3, the long-acting version of insulin-like growth factor. This peptide directly increases protein synthesis, accelerates muscle recovery, and stimulates local growth, especially in combination with training. I started with 30-40 mcg post-workout subq, and after 4 weeks I already felt better pump, faster recovery, and finally visible gains again (fuller shoulders and legs). After 8 weeks, I gained 2-3 kg of pure muscle mass without much fat. I bought it at
https://redmondpharm.com/nl/peptides/igf-1-lr-3/ – reliable site, fast delivery in the Netherlands, original product with lab tests and fair price. If you're plateauing at the gym and normal supplements aren't working anymore, IGF-1 LR3 is really next level – for me, it got things going again.
