Cypionate 100 mg/ml vs 200 mg/ml

Wondering if someone can help me understand the difference between Cypionate 100 mg/ml vs 200 mg/ml in terms of benefits / drawbacks. I get the 200 mg/ml is more concentrated, so I guess that could me it’s stronger option compared to 100 mg/ml

I was on 0.2ml of cyp 200 / mg/ml twice a week but I’ve now been moved to 0.6ml of cyp 100 mg/ml. Is there going to be a material difference in benefit, if moving to to the 100 mg/ml at a higher dose compared to a lower dose of the 200 mg/ml

Sorry if this seems a dumb question

If it’s the same ester weight there should really be 0 difference between the products aside from the amount of oil your injecting.
That being said, your dosage has changed.
.2ml of 200mg/ml x 2x/week is 80mg/wk
.6ml of 100mg/ml x 1x/week is 60mg/wk unless you meant 2x per week in that case your at 120mg/wk
Why did they make this change?

Sorry yeah
0.60ml of cyp 100 twice a week

Ive moved clinic / dr, who wants to administer test only. So he removed HCG and anastrozole to see how I go and review in 6 weeks

This is a way better scenario.

Hopefully my friend
I like the more logical approach this Dr is taking

Previous clinic I think on reflection could well have been thinking profit over patient, given they had me on multiple meds all at a cost

Hey buddy
Was wondering if you could elaborate on this. As I’m still not sure I understand the difference. But understand Im going to be administering more per week at 0.6ml twice a week vs 0.2ml twice a week

Each type of testosterone carries a different ester. This is what allows the release of the drug. The heavier the ester weight, the slower the release but also the less relative content.
Ester weight Relative content %
Test suspension 1.00 1.00 100%
Test propionate 1.19 .84 84%
Test Cypionate 1.43 .70 70%
Test Enanthate 1.39 .72 72%
So the higher the Molecular weight the less test you will get milligram per milligram.
If you took 200mg/wk of prop you would be taking more test than if you took 200mg/wk of test enanthate.
The lower the ester weight the more efficient the delivery is.

Thanks bud
So is cyp 100 @ 0.6ml twice a week I should see me OK administered IM ?

Sorry in learning from scratch

? Lets try that again.

Sorry pal

Just trying to gauge if moving from Cyp 200 mg/ml at 0.2ml twice a week to Cyp 100 mg/ml at 0.6ml twice a week is going to be better / same or not as effective

From my prior post:
.2ml of 200mg/ml x 2x/week is 80mg/wk
.6ml of 100mg/ml x t 2x per week in that case your at 120mg/wk

Your going from 80mg/wk to 120mg/wk. of cyp.
Will it be better/more effective? Time will tell. I’m sure in the short term you will feel great but…

That is a low dose either way imo for TRT purposes, usually guys are in 140-200mg per week range for TRT either in one shot or split across two, your new dose is closer to the ‘normal’ dosing but I would still consider lower than typical dosage range.

Unless you’re trying for kids don’t take HCG. Anastrozole is good for on hand but unless you get symptoms I would take sparingly not just by default every week.

One shot a week is also generally fine intramuscularly though some people seem to find that two will give them a bit less peak and trough. If you went straight to two. May want to try one as it’s less of a pain in the ass (literally)

I take 100mg a week of test cyp 200 but they also told me to take 0.1 ml twice a week of hcg. I’m 50 and don’t want kids, it’s an extra £40 a month for the hcg. Do I not need to take it ?

The benefit of HCG is that is preserves fertility and it will prevent any testicular atrophy. If you’re not trying for kids this isn’t a problem for most, so not something you should generally add in. There is an outside risk that fertility won’t fully restore if you come off TRT in the future, and HCG would offset that risk, but for most, HCG isn’t worth it/necessary unless you are imminently planning for kids

Dr I’m now working with said most of his patients including himself respond well to 0.6ml injections twice a week of Cyp 100mg/ml. But I guess everyone is different, some will respond, some won’t, some need lower, some need higher. The main thing for me, is that I’ve moved to a clinic, that’s a lot more methodical in their approach to TRT. Not throw 3 different meds in the mix and see what sticks, making it hard to decipher which protocol is most suited for me

New Dr has removed HCG and Anastrozole from my prescription. No plans to add HCG back into the mix, since I told him fertility at 43 isn’t important to me. But he did say should that change, the we can discuss adding this back in. Anastrozole is now only to be on hand should there be any symptoms

New meds arrived today and protocol starts Thursday. So I guess I’ll see how I go on test only TRT at a slightly higher dose and IM injections vs SQ, over the next few weeks with a full review in 6

Good that you’ve moved to someone who is working incrementally, it’s a red flag when they throw 3 things at you at once.it depends on your goal as to dosage, at my clinic we aim to get guys (presuming they have no underlying health risks) close to optimum levels naturally (total t peak of 900-1100). To achieve this we typically dose 140mg - 200mg a week, single IM shot of 200mg/ml test C. We have a couple of guys who do twice weekly as a personal preference but vast majority are in the range above with a few outliers on either side. I would ask for a blood test 2 days after injection after a. Few weeks to see your level at peak and if it’s anywhere lower than 900, ask him to raise dose (assuming you’re looking to get into 900-1100 range)

TRT is about symptom relief. Not pushing numbers. Ideally one should take the minimum dose required to relieve symptoms with little to no side effects.

Again, this is chasing numbers. Not TRT.

My last bloods my F T and T T was

Free-Testosterone 0.731 nmol/L the range is 0.226 - 0.65 nmol/L
Total Testosterone 23 nmol/L the range is 12 - 30 nmol/L

My previous clinic was aiming to get my TT close to 30 nmol/L. My new clinic is aiming for a range between 25-30 nmol/L and ideally a level where I’m symptom free and no sides

That is what you are looking for. Do not chase numbers. IMO the advice you were givin was not responsible.
