i have ran into a dozen people that have informed me the healing powers of deca. i keep getting strains in my back, shoulders hurt, and left pec is hurt. every 1 said that deca will take care of all these problems, that it fixes just about everything. IS THIS TRUE OR HOW MUCH IS TRUE? also is taking low amounts of tes over 20 weeks better than doing it double in 10 weeks, which has better results? tnx
