No such thing as a āhardgainerā, just people who donāt like to eat a whole lot and havenāt figured out the liquid calorie solution yet. Highest run I have done involving Deca was Test+Deca at 1g/wk apiece until I ran out of em (somewhere around 22 weeks give or take a pin), and the lowest I have run is 600 Deca on cruise dose of Test. Iām one of the people who gets the (likely placebo) joint health support from the drug, but this is an individual basis thing- Not everyone reports this effect, same as how some people respond poorly to anadrol and get gyno no matter what while others never get it.
On any run of Test/Deca I have looked fuller 24/7 and higher volume training seemed to be easier to perform and also recover from although this could also just be due to the programming I ran while on the compound. I did hit my best raw bench while on the 1G Test/Deca run, but I am not fully sold on the idea that I couldnāt have also done the same weight or more on 600mg.
The doses I ran are purely out of convenience and price- I found some 600mg/ml vials of Deca going cheap at one source so thatās what I ran, and then my highest run I found 500mg/ml dosing and was just gonna do 600 again but Iām incredibly lazy and itās easier to just measure a consistent 1ml each pin so I ended up at 1G/wk total, same for the Test which was also 500mg/ml vials. I do not really advise that as I cannot say that the higher dose worked better in any quantifiable way.
Iāll be running very low (200-300 depending on what sources are selling) Deca in my next blast just hoping to get the joint support more than anything.
Iād advise you just try a cruise dose of Test and a moderate amount of Deca to start and just see how that goes before stacking, otherwise you wonāt learn how your body reacts to just the Deca.
