Mast VS Primo

ad

After a little research, I read that these 2 compounds are interchangeable and make similar results from some. Others say that Primo gives a more fuller look than the Mast. With the Mast being the more budget friendly option, compared to the expensive Primo, what are your opinions and experiences with these 2 compounds? Also, they both come in Enanthate, Propionate, and even oral forms. What differences did you notice between them?

I just realized I typed Primo is made as Prop, I was referring to Primo Ace (Methenolone Acetate).

IMO...... regardless that it is nigh impossible to find real primo these days, the fact is that it is played out!.. only being dosed at 100mg/ml is a pain in the ass literally because a male needs to pin a full gram every week to get the best from this compound, "oral version" well!.. if you can get results from that crap yous a better man than me gungadin lol.

MAST is the evolution of primo.. gives more or less the same finish, brings along Ai as a freebie,.. i use Mast E year round in every stack only switching to short ester Mast prop for ED pinning when comp prepping.

So to conclude.... lets put primo depot in the"!womens box" along with Anavar and Winstrol.... these compounds have NO purpose for the serious bodybuilder this day and age, Masteron alone is far more productive than these 3 compounds all stacked together..... and leaves you a serious amount of cash for spending on what REALLY MATTERS.... either cutting or bulking and that my hombres is FOOD.

UGH!! after reading this I'm debating on even running a good bit of primo I've collected.. Probably a waste of money .... Time to buy some mast again...

I never looked at Mast as a replacement for Var and Winny. It makes sense, Mast does what they can do.

We (grrl) dont carry Primo for that very reason---it's hard to ensure that you can get good quality raws.
On the other hand, Masteron is probably my favorite steroid----it has great estrogen-blocking qualities, it gives you FANTASTIC vascularity, plus you can run it at very high dosages with not near the drawbacks of harsher compounds.

I didn't realize it was difficult to locate reliable raws, with a good price of course, that have consistent amounts of it. I have seen a few sources getting Beaker to test their Primo with positive results, but when I calculate the amounts of Primo needed for a proper cycle the cash keeps on rising.

I agree! mast has quickly become a fave... I'm running 600 test/600 mast/800 eq right now with no AI and not a drop of bloat nor a single nip itch

I wanted to bump this to get some more feedback.

I also read that Primo is stronger than Mast:

Masteron Anabolic/ Androgenic rate: 62/25

Primobolan Anabolic/ Androgenic rate: 88/44

So, is it worth the extra cash?

big difference to me is cost of the raw for Masteron is much less. The probability of getting authentic properly dosed primo is low because of the availability and cost of the powder.

Yeah, I'm about to add some Mast Prop to the same NPP/ Test P cycle I ran last year.
