Primo Brewing Question

Morning Gents,

I come to you seeking knowledge on Primo and bow to your experience. MOST Primo (Methenolone Enenthate) is brewed at 100mg/ml. Pharmacom is an exemption with some 200mg/ml Primobolan.

Is this done due to low solubility? Or is this done because Primo carries PIP at higher doses?m Are there any other major pitfalls or challenges that one might expect brewing Primo?

Interested in brewing up some Primo and I like the idea of 150mg/ml to split the difference, as I've found myself more sensitive to volume of the injection more so than the concentration.

Thanks for any answers.
