There isn't a Primo Propionate cuz of it's bad Solubility & stability.
Short esters like propionate make it less oil soluble, meaning you’d max out at very low mg/mL (like 50–75 mg/mL). Nobody wants to pin that much oil.
A 100mg/ml primo prop would have insane PIP and probably crash and cause irritation.
Now to bring it back to why Boldenone doesn't come in shorter ester:
Boldenone base is very oily, and only very long esters (like undecylenate) give it workable solubility. Same issue as primo, shorter esters make it crystallize easily thus painful injections.
Also EQ was a vet drug for horses so long-acting dosing was intentional. Short esters were never pursued clinically, and UGL avoid them because of solubility issues.
Also it sounds like a bad idea if you think about it.
There is no payoff making is fast acting, Bold/Primo are a slow, steady, low-potency compounds. Making them “fast” with prop/cyp wouldn’t suddenly turn them into Tren or Test, it just doesn’t deliver enough anabolic bang to justify the hassle.

Yeah it was never a successful pharmaceutical product.
Fucking painful, low concentrations to make it tolerable, and just redundant if you already have a enanthate version.
I rly wished I could try primo before it became a fucking luxury to have.
