A friend of mine injected one sust nile (old batch). 72 hours later after a heavy leg press workout he started to feel bad, no pip, just general weakness. Like a flu. He was hot all night long and can't sleep. Then pain in the knee and lower back, then headache, no appetite, and sweating like hell. After a shower he got cold and shaking. Then muscle cramp in the neck, finally it gets better but he lost two day of training.
He injected sust alone, he already used the same batch but mixed with bold and everything was ok.
Does that mean the gear is bad ? overdosed ? Should he use the sust mixed to ease the absorption ?
Does vit c and aspirine are all he needs ?
