I am currently running test suspension right now, along with a test enanthate, tren enanthate, and some drostanolone enanthate.
I use the test susp on workout days post workout. The injections can be painfull, depending on where you inject. I don't get much pain in the delts but the quads can get sore.
I notice a definite increase in libido shortly following an injection, but within 12 hours the libido has swung the other way, and is actually decreased, even though I am running all the other test and masteron.
I am using femara as an AI with it.
I am noticing some gains. I have been on since Dec 1st so naturally gains have slowed. Water retention isn't noticably increased since I started the test susp.
As for the product itself, the crystals are extremly fine, it is UG. the product looks like milk, and you can draw and inject with an insulin pin.
Sterility has not been a concern, as the way suspensions are made - the powder is disolved into a liquid with heat, and is then filtered into cool sterile water where it recrystalizes, so as long as sterile technique is maintained throughout the entire process, the product is guarenteed to be clean.
It is definitly a lot finer than winstrol depot preparation, and I suspect it has to do with it not having the 17-AA group.
Overall it is a product worth trying. I will be experimenting in the future with other suspension products such as tren, and boldenone base.
