Two years on the needle...

56 days is standard per their site but that's conservative. some compounded versions say 90 days, maybe 100 max. potency drops over time but the real issue is contamination each time you poke the membrane.
 
I'm a few weeks into my compounded batch and started noticing something weird - when I pull the needle out of the vial, a little squirts out. Happens every time now and I lose some each shot even though I follow all the rules. Didn't happen at the start so not sure what changed.
 
Capillary testing has real limitations for hormone-dependent protocols. The sample quality issues with fingerprick for certain analytes - particularly testosterone and some lipid fractions - mean results can be unreliable enough to make decisions on. For monitoring in that context, venipuncture panels give the full picture that fingerprick methods miss. The cost difference between the two has narrowed with some of the concierge lab services, which makes the tradeoff less compelling than it used to be.
 
Two years at a stable 1600-1800 with insulin resistance improvement is the long-term outcome the data predicts but most people don't fully believe until it happens to them.
