deca shots and cycle lenght

[josenunes]

I wish to clarify a doubt that I have , deca long esters stay on the organism for at least more 20 days from last shot so a 3 shot deca cycle its equivalent to a 6 week cycle with a short ester compound , right ?
By the way , after the first use of a vial does it needs to go to the fridge or in a dark cool place its nice?
THANKS BROS

Say u injected 400mg a week for 3 weeks of deca and its half life is around 14 days (this varies a little from source to source).

Week 1 400mg
Week 2 400mg + approx 282mg (from week 1 shot) = 682mg
Week 3 400mg + 482mg = 882mg

In 21 days u will still have about 311mg, in 42 days about 110mg.

So in a round about way it is like running a shorter ester for longer.

Room temperature is fine for storage

BTW for those of u that r curious and remember some math, most biological growth or decay (particularly half-lives) follow the continuous growth/deceay exponential model.

ae^(kt) where a is the initial value, e is the constant 2.718....., k is the growth factor, and t is the input variable (in this case number of days)

u have to solve for k first. 400e^(k*14)=200 since we are assuming that 14 days is the half life of deca.

u will need to use logarithms to solve (skipping details) and u will get k = -.0495105.

finally we have 400e^(-.0495105*t).

now u may ask well we dont always have 400 such as in the case of week #2. the initial value does not matter. without giving a math lesson as to why we just continue to assume that it doesnt. the geeks can pm me for explanation and proof as to why it doesnt matter.

Say u injected 400mg a week for 3 weeks of Deca-Durabolin - nandrolone decanoate - and its half life is around 14 days (this varies a little from source to source).

Week 1 400mg
Week 2 400mg + approx 282mg (from week 1 shot) = 682mg
Week 3 400mg + 482mg = 882mg

so at that dosage when should PCT start?in the end of week 6?

I made the question cause I heard a guy in the gym saying that he does Nandrolone Phenylpropionate stacked with dianabol for 6 weeks cycles , so I believe that for a similar cycle with deca we only do 3 shots, right?
Thanks for your answers

there is only one problem with all this, though nelson might disagree, i think deca needs to be run min 10-12 weeks for full effects. so imo this hyopthetical cycle is a waste.

Personally I coudnt agree more. I never start feeling its effects until week 3 or so and it gets better as the cycle goes on stick with at least 10 weeks
