Primo or Mast

with a 250mg Test base!

Primo/Mast dosed at 400mg.

Goals - 12 week lean bulk, wanting to add dry tissue, as little water as possible (diet dependant I know). I’d also like to run the one which is the healthiest.

I’d not want to run three compounds, so a mix of all 3 is a no go.

Which would you choose and why?

Mast is pretty much a cosmetic compound used near a show or photoshoot.

Why don’t you tell us why you have selected these compounds?
You also give us 0 info about yourself and your past experience with gear.

Thank you mate.

Tbh I’m just curious to what people’s opinions are in real world use. Research suggest primo will add more tissue and is healthier, where as mast is good for e2 blocking and a dry look, ideal cutting, shining under 12% bf.

I’ve ran 500mg test with good results, but don’t like the ideee of blowing up much. Test put 17lbs on me in 14 weeks. Kept 11lb.

I was going to do 250 test 400 mast. But it seems primo maybe a better option for my personal goal.

I just like learning too, hence this question.

Primo is def better for tissue growth. Mast is a weaker compound and the AI aspect is hit or miss. Some guys will run low test and higher mast and bury their E2. I am not one of them. Neither primo or mast effect my E2.

If you kept 11lbs on a 14 week cycle i would consider that a success for sure.

I would def use primo over mast. Mast has it’s place but not in a growth cycle.
250test and 300-400primo for 12-14 weeks would be a good cycle. Of course you will need to eat in a surplus and if you wanna stay lean you’ll need to eat clean.
Start up a training log so we can follow this!

I know I’d get bloods done, but at 250:400, would you use an AI for the primo? What about adding 100/200mg mast?

I’ll definitely start a log

I would certainly have one on hand if needed but at thoses doses I would not

Why?

Primo is a DHT like Mast. It affects the body similarly. Likely no need for an AI but good to have in case.

from what ive heard, when people fake primo, they use mast as the replacement compound.

Why? because its cheaper and feels/acts pretty much the same with respect to possible AI, elevated test, no estrogen, etc.

If the two were the same price, I’d go for primo, but its often twice the price, IME.
