Cardio.....How much is too much?

[Half_Natty]

I'm currently in week 5 of running 500mg Sus and 300mg of NPP a week.
I usually run about 3 miles every other day at a decent pace, around the 7-8 minute mile mark. I was doing this way before I started the cycle but i'm starting to notice some increases in my speed and endurance doing this now and I haven't really been pushing myself hard enough in my eyes for these changes to come naturally so i'm presuming its from the drugs.
I'm worried about if i'm over doing it or not on my heart. When i finish running it doesn't really take long for my heart rate to return back to its resting rate. But it is going like the clappers by the end of my run.

Any thoughts would be appreciated,
Thanks!

Are you taking an aspirin a day or any other supplements?

 

[Stackinplates]

What do u get ur heart rate up to? Bpm?
Resting heart rate as well?
Are u doing intervals?
Do u take pre workout?

Cycle support?
Keep eye on ur bloodwork high rbc can be a issue

I take taurine daily and i use caffine and Beta alanine for my pre-work out on the weight but not running. Apart from that it's just my vitamins.
Why the question about asprin?

I haven't checked what my HR reaches but resting is at 60bpm. I'm not doing intervals but there is a hill about 150m long that I do sprint up on my run but other than that its just a steady pace.
No pre workout before a run apart from a bowl of porridge with a banana if that counts....

What is rbc? Red blood count? As in high blood pressure?

Im lucky enough to be living in Manchester, UK, where there is a place called the Pump Clinic ran by the NHS, so I can pay a visit to get some bloods done for free.

There is NOTHING wrong with your heart if you can run that fast and recover quickly. My only concern would be loss of mass if you're into mass building

Thanks that's good to know. My only concern was about it growing really....From my understanding it can grow due to the drugs because it's a muscle which can cause major problems can't it? Forgive me if i'm way off here Still pretty new to all this!

Oh ur worried about heart growing

I see though u were worried about heart pain or racing to fast

Yes it is possible with prolonged use

But also the heart is a muscle and the more u work it cardio at high speeds then it can grow
Plain and simple

No I've not really felt anything to be worried about to be honest.
Yes that's mine initial concern. How much would you class as prolonged? Is that prolonged cycle length, running time, intensity?

How much is too much?

 

[Stackinplates]

Im not a doctor so I don't know

All u know is I had a Buddie that developed afib

Google it read up and do ur homework ... Afib and steroids in the heart

Plenty of risks with any medication


Afib is one

But Google enlarged heart or valves

While I don't turn a blind eye to the potential effects of steroids on the heart, I doubt that you're dealing with a serious enlargement problem here, given the details you've offered. Here's a good study from years ago showing that AAS use alone doesn't usually have a profound effect on size or function:

BACKGROUND: Adverse cardiovascular events have been reported in bodybuilders taking anabolic steroids. The cardiovascular effects of AAS, however, have not been investigated in detail.METHODSWe recruited 20 male bodybuilders (aged 35 ± 3 years), 10 actively using AAS and 10 who denied ever using steroids.

Serum lipid and hormone levels, carotid intima-media thickness (IMT), arterial reactivity, and left ventricular (LV) dimensions were measured. Vessel diameter was measured by ultrasound at rest, during reactive hyperemia (an endothelium-dependent response, leading to flow-mediated dilation, FMD), and after sublingual nitroglycerin (GTN, an endothelium-independent dilator).

Arterial reactivity was also measured in 10 age-matched non-bodybuilding sedentary controls.RESULTSUse of AAS was associated with significant decreases in high density lipoprotein cholesterol, sex hormone binding globulin, testosterone and gonadotrophin levels, and significant increases in LV mass and self-reported physical strength (p < 0.05). Carotid IMT (0.60 ± 0.04 mm vs. 0.63 ± 0.07 mm), arterial FMD (4.7 ± 1.4% vs. 4.1 ± 0.7%) and GTN responses (11.0 ± 1.9% vs. 14.4 ± 1.7%) were similar in both bodybuilding groups (p > 0.2). T

he GTN responses were significantly lower and carotid IMT significantly higher in both bodybuilding groups, however, compared with the non-bodybuilding sedentary controls (p = 0.01).CONCLUSIONSAlthough high-level bodybuilding is associated with impaired vascular reactivity and increased arterial thickening, the use of AAS per se is not associated with significant abnormalities of arterial structure or function.
