What’s the whole deal with Test Prop?

I am genuinely curious

I see so many people here advocating for Test P instead of C or E, but why?

If you compare all three with the same injection frequency (ED), I don’t see any benefit of Prop over the other 2.

Also, on other bodybuilding forums plp usually trash P, and Cyp seems to be the gold standard.

Some arguments mention water retention and e2 levels but that is not ester dependant, it just has to do with injection frequency like I mentioned.

Perhaps it has to do with the build up in serum concentration from the longer esters, or the longer time you need for pct.

Erectile Dysfunction?

It’s supposed to be literally the opposite, you are on test, so your going to have crazy boners.

Also please don’t inject once per week, unless you want to get the side effects from the peaks and throughs.

Injecting ED or at least EOD is law

yeah I guess that might be the only reason, in case you wanna titrate faster or PCT sooner.

I’m currently trying to figure out a way to use P at the beginning and end, and C in the middle of the cycle.

The main issue is keeping total serum testosterone levels stable during the exchange of esters

Yea thats a good idea. I still think mainly using test e or c would be better than using test p, though, when you weigh the pros and cons.

Test P has more Test per mg than other esters (apart from A which is equal)

Mark solution

bro the weekly dosage is the same lol

instead of injecting it all once per week, you simply divide it into daily injections

That’s def not the reason IMO lol

Yea it’s true that the ester weight of P is lower than C or E, meaning that prop has more test per mg, but it’s just a ~15% difference.

So it’s not a huge deal to just dose cyp a bit higher in order to get the same mgs of total test, while still reaping the benefits of C (or E).

I guess the only valid reason is to titrate faster and PCT sooner like I mentioned previously.

But so many users on this forum swear by it for some reason.

Unfortunately, only people who actually do test know how much worse the PIP of P is compared to C though

I think the two best options are either P or E, there was a study comparing C and E demonstrating that E had much higher peaks than C. So those are the only two options I would really consider.

I'll have to read more shit on both to decide what to pick for my cycle though
 
I thought it was the increased freq rate of injections and to control how much exo test you have at a time. More freq injec more stable hormones means less sides

Idk id assume its because they have a bit more "freedom" at adjusting doses and seing the effects quickly

Personally i havent tried it so i cant compare, might switch to test p sometime to see how i feel just due to the vast amount of anecdotes but for now cyp is just so much more convenient

yeah I guess ur right, it's great to titrate and PCT quickly

I’m trying to find a way to use P at the beginning and end of the cycle, with C in the middle.

The main challenge is keeping total serum testosterone levels stable while transitioning between esters.

Sounds pretty tricky to get it right, id probs just not bother and run test p the entire cycle

yeah I'll most likely end up doing that, but there's 2 main issues.

1) I keep hearing that Test P PIP is rlly bad so idk (might add some MCT to dilute even more if needed)

2) I'll go on a 4 day vacation mid-cycle, and I can't bring Test with me, so I'll most likely need to switch to C temporarily so...
 
I just do E or cyp every day

Longer esters pinned daily are best imo given you know how you react to the compound (since you can’t pull it quickly obv)

Yea tbh I alr bought 3000 mg of Test P (dumb asf lol) just bcs so many people on this forum swore by it.

The main reasons were that I thought it caused less bloating (which is false) and that I could PCT sooner (that part is true).

Now that I think about it, since this would be my first cycle, it might actually be better bcs I can pull out quickly if I react badly

That said, I keep hearing a lot of bad things about Test P PIP, so I’m considering buying extra MCT oil in case I need to dilute it down

pretty sure to avoid hormonal spikes and whatnot to avoid acne/pimples

yea, but that has nothing to do with the ester itself.

That just comes down to injection frequency.

So if you pin ED even with C or E, you won't get hormonal spikes (and acne or pimples).

Yea and actually the ups and downs are less if you pin cyp or E every day vs p

Yea, exactly.

The thing is Test P is supposedly closer to mimicking natural testosterone spikes in the body (if you pin in the AM).

That might be why so many influencers like MPMD and Clav switched from C to P.

I also bought test P after hearing the shilling on here and the PIP is brutal at 200mg/ml

I’m probably going to have to dilute because I can’t sustain this. Prescribed TRT test P uses like 50 mg/ml

yeah it doesn't surprise me at a 200mg/ml concentration.

look at this guy who had the same problem:
https://thinksteroids.com/community...ter-using-test-propionate-200mg-ml.134434060/

Honestly, just check what carrier oil it uses and buy extra oil to dilute it.

Warming the solution before injecting and massaging the area afterward also helps.

Yeah I tried warming last night and nothing changed.
warming the solution mostly helps with solutions that easily crystalize (low BB concentration)

But if yours doesn’t have that problem, what matters the most is the concentration as well as massaging a bit afterwards.

idk but you could just split ur test e/c injections into ed or eod and have more stable levels then test prop. Also if you miss a couple of days of injections you will feel like shit.
