Love Sustanon. Use it all the time. Currently on week 6 of 18 of 800mg a week shot eod. Just taking the Sus, going to introduce some Masteron and test prop on week 14-18 to Harden up and help solidify gains towards the end of cycle.

When a person experiments and finds the best dosage and pinning times for themselves sustanon can be used for both bulking and cutting due to the drier gains it gives towards E or C .. i must admit i am a big sustanon lover and find EOD shots work best for me,.. a good lean dry gaining stack is sustanon + boldonone (EQ) i dont see this stack used alot on here but believe me its a little cracker if pinning shedule is stuck to like religon to keep plasma levels stable... far exceeds the finish that E or C would produce and is a great stack for prepping for the summer beachs without going down the tren route.

I personally prefer test e/c. I used to be an avid used or sust, but once i had tried test e/c i began to use that as a base for all of my cycles.

I've done a little research before hand on the benefits/drawbacks of each, and have written them below:

The main variable in comparing esters is their affinity towards water retention, and at what rates the sub-cutaneous water retention is experienced. Experienced AAS users will strongly agree that the water retention experienced through running a long-estered variant such as testosterone enanthate in comparison to testosterone propionate (whereby the main compound in each product is testosterone) is significantly higher. Therefore, these experienced AAS users will tend to use the longer estered variants in their off-season and the short ester variants towards pre-contest preparations. Additionally, these sides such as increased water retention from long-estered testosterone help increase the chances of obtaining other sides such as gyno.

Another point to consider, which i have read more frequently recently is that some of our members claim that shorter estered variants are more potent than their longer estered counterparts. Well, not necessarily since they have the same compound to which the ester is attached to - however, the main difference is that in a 10ml vial of testosterone propionate, there will be a higher percentage of testosterone in the vial, in comparison to testosterone enanthate whereby there is an increased amount of ester weight.

When an ester is attached to a compound the ester makes up a percentage of the total weight of the compound - for example, testosterone cypionate contains 69.9% testosterone per mg, whereas the cypionate ester makes up 30.1% of the total weight. However, testosterone propionate contains 83.7 mg of testosterone, per mg and its ester weight is 16.3% of the compound. Additionally, since shorter esters release the parent compound into the human bloodstream at a faster rate, gains are recognised at an increased speed.

Below is a list of the more commonly used esters, which have been grouped together according to the percentage of testosterone they contain per mg - additionally, i have added breakdown of how much money is spent on the product and how much is spent on the ester (based up on RRP in USD ($) of a 10ml vial using common dosages - Rested Retail Price (term used loosely LMAO).

Percentage of Testosterone per mg - RRP ($) - Value of test - Value of ester

No Ester: 100mg---------------------$45--------$45-------------$0
Propionate: 83.72mg-----------------$35--------$29.3-----------$5.7
Enanthate: 71.99mg------------------$45--------$25.2-----------$19.8
Cypionate: 69.90mg------------------$45--------$24.47----------$20.53

Now, you may say, that maybe i should use a blend which encompasses multiple ester lengths such as Sustanon. Sustanon is great for pinning E3.5D/twice a week, but there are three faults;

1) Since it is a blend, the measurements of each compound are much weaker, thus producing results in inefficient amounts when compared to a single estered compound.

2) Pinning twice a week will make you're blood levels volatile, since sus contains prop, and I don't believe pinning ED or EOD is an option either, since there will be a build-up of longer-estered compounds in your system producing variable, un-tame results.

3) Ester length effects more factors than simply injection frequency and release rates - it also effects water retention, net protein synthesis, gyno risk, influence on estrogen conversion.

Finally, I believe that sus is not cost effective. I say this because the longer-esters take up 'more room' so to speak than shorter esteres. So, imo, if you were dead set on taking sus, then I would buy a vial of prop, a vial of phenyl prop, a vial of iso and a vial of deca and mix accordingly. This is for two reasons, to ensure that the sus is not under-weighted (like many products on offer), and to maximise cost efficiency.

Hope this helps,

I think most will agree that you have more control and stability with a single ester. Whetjer it be prop, cyp, enth, etc. For cutting, bulking, cruising, whatever. Some will swear by sust. UI'm a control freak so I don't like it. Test E bro
