I’ve made my own brew with 2%BA, 4%BB, and 10%EO, and the rest grapeseed oil. Always painless shots.
I have never used a higher percentage of EO, so I couldn’t really tell you what that would do to a filter.
What is the purpose of such a high percentage of EO? Are you not including BA and BB? Since EO is a solvent are you sure that is a good idea?[/quote]
I’ll still be including BB and BA, I just meant that the rest with some batches will be all EO. The purpose is for solubility. I’ve got some recipes for 600mg/mL test enanthate, 200mg/mL NPP, Tren and primo and various others at pretty high concentrations. Its a pretty good solvent. Tren can be brewed up to a fairly ridiculous concentration too from what I can gather. I’m also going to try some of these brews SQ as a well so as high a concentration as possible is needed.[/quote]
I’ve used T400 and that had enough solvents in it that it was hard to walk or sit down for a few days after injections. Since then I’ve had a different view of highly concentrated gear.
From an old Cy Wilson artice:
In general, the longer the carbon chain of the ester, the more lipophilic (fat loving) the androgen molecule is and thus the more you can dissolve in the oil (solvent) without the use of a co-solvent (e.g., benzyl alcohol, benzyl benzoate).
In order to achieve the same concentration with shorter carbon chain esters as you would with a longer carbon chain ester, you’d need substantially more co-solvent. The problem is that the typical co-solvents we use can cause hypersensitivity reactions (nausea, vomiting, headaches, inflammation at the injection site) as well as irritation and even necrosis (tissue death) if high enough concentrations are used
