NICE!!!! I assume with your plan is to use all of these and possibly run an 8 week cycle, so let me lay out how I would run it and why.
First 1-Andro and 1-Alpha are the same base PH but 1-Alpha has an enanthate bond to make it's half life much longer so it is more bio-available. You could add this in at the beginning and or honestly anywhere in the run since it will simply just increase the amount of 1-Andro hormone you have in your system. Me personally I think I would add it in at the end when your receptors are getting used to it just as an increase in dose of the hormone.
Okay rather than a dissertation on everything then laying it out I will just lay it out with a few explanations.
1-Alpha 4 a day 2 in AM 2 PM
1-Andro weeks 4-8 @2 a day 1 AM, 1 PM
Decavol weeks 1-4 @2 a day 1 AM, 1 PM
DecaSarm weeks 4-8 @2 a day 1 AM, 1 PM run this after the decavol due to increased dose of main ingredient, again receptors being considered.
4-AD Weeks 4-8 @2 a day 1 AM, 1 PM - I say run this the last 4 weeks because by this time you will have started to shut down a little bit. The 4-AD ingredient converts to testosterone at a pretty high rate so this could combat lethargy and any drops in libido since 1-Alpha nor 1-Andro is androgenic they will not give you any libido and are known to cause some lethargy.
That is how I would run them with what you have, I would expect the to be some very nice gains from this stack for sure. The Decavol and Decasarm should help with your joints which is good because the 1-Alpha is gonna give you some nice strength gains once it really kicks in. The 4-AD will help combat the lethargy and libido issues later on in the cycle so you should feel pretty good. I think this will be a great run and I hope you log it.
