Has anybody tried this? its original but im not sure if its very underdosed.... im just starting this tren and im not sure about the quality of it, ive done already 400 mg in one shot 4 days ago and i wanna do tomorrow 400mg again just to front load, if its real i might be fcked up but if its underdosed i should be alright, i can manage until 400 mg of real tren E, im just frontloading now,then ill pin just 300 weekly, i bought it through strengthandsteroids.com , there are not too many reviews about Optimum Biotech but the few reviews i found looked alright, has anybody tried this? the vials look very professional but its still an UGL.
