Maybe you could try using an infrared lamp to boost collagen extensibility.
“Tissues heated to 45 C and then stretched exhibit a non-elastic residual elongation of about 0.5 – 0.9% that persists after the stretch is removed which does not occur in these same tissues when stretched at normal tissue temperatures. Thus 20 stretching sessions can produce a 10 – 18% increase in length in tissues heated and stretched.”
You could try shining it through your pump.
I personally decided against dmso.
“Neurotoxicity could be detected at doses as low as 0.3 mL/kg.”
A 70 Kg man would have to use loads to put himself at risk, but if your using a small amount everyday it could have a dangerous cumulative effect.
