IGF-1 (Insulin-Like Growth Factor 1). IGF-1 or insulin-like growth factor 1 (brand name: Increlex) is a growth factor which is very closely related to insulin. It carries the same amount of amino acids as insulin and responsible for the anabolic reactions to GH.
Spring pressure is the key factor in determining which spring should be used for which application. Camshaft design also plays an important role in determining which spring you will need. Lift is the critical spec when matching valve springs to the camshaft. The more lift you have the greater the pressure needs to be.
This new Lite Pressureâ¢ Series has been developed so that, for a given length and diameter (outside or inside), there would exist a series of springs that had lower spring rates or workable load ratings than what is currently offered by the existing Lee Spring Standard Series compression springs.
