Stanford, when you say that your Test Enan 300 is "mostly Test Cyp", can you go into a little more detail? Like is it approximately 180mg Test Cyp / 120mg Test Enan.....or 200mg Test Cyp / 100mg Test Enan ....... ?
I ask because it does make a difference to me. Test Enan and Test Cyp have very different half lives. Even though they differ by only one carbon (Enan 7 C's, Cyp 8 C's), if you look at the molecular structure of the 2 esters, they are totally, completely different which accounts for their very different half lives (Enan = approx 4-5 days / Cyp = approx 8 days). Enan is a 7 Carbon straight chain, Cyp is a 3 Carbon straight chain Propionate ester with a 5 carbon ring attached to the terminal Propionate Carbon. Enanthate and Cypionate are very very different esters even though they differ by only 1 Carbon. Thus they have very different half lives.
I have always preferred Enathate and have used Enan in 95% of my cycles due to you getting a little more Test per mg with Enan......
Test Enan MW = 400.603 g/mol
Test Cyp MW = 412.614 g/mol
Pure unesterified Testosterone MW = 288.42 g/mol
Test Enan = 288.42 / 400.603 = 72.0 % Pure Unesterified test
Test Cyp = 288.42 / 412.614 = 69.9 % Pure Unesterified test
Although I prefer Enan over Cyp, my last 2 sources for Test Enan 300 were actually quite painful, as I believe the Test Enan raws they used had sat around for awhile and become oxidized, leading to the Test Enan PIP. So I completely empathize with you adding cyp to the test Enan trying to cut down on PIP for your customers. Have to keep your customers happy !!
I look forward to placing a nice-sized order with you in the next week or so Stanford. Thank you in advance for answering my question !!
I believe the pip is from the manufacturing process of the raw materials, but I'm not sure anyone is positive of the why. I don't think it would be due to the age and oxidation of from this. Reason i don't believe such is test e turns over very quick. It doesn't sit very long. It's here and gone very quick. Almost can't keep up.
But, to answer your question, the blend is roughly 160c/140e split. I do overdose slightly so the number isn't exact, but pretty close to it.
