    Has anyone had any really bad sides with PT-141?

    I tried my 3rd shot today after giving it a break for a week. First should was 125, then 250, and today was 375mcg. Flushed again today... so 3/3. On 250mcg I felt a bit of nausea, but after today's 375mcg I have some low grade nausea 5 hours after the shot. It's hard to gauge whether or not...

    I am extremely sensitive to Testosterone Cypionate.... Low dose?

    These things go away. You just need to wait. Both times I started and restarted TRT I had a horrendous time sleeping and now even when I triple the dose I sleep fine. It's just the adjustment period.

    Primo for estrogen management!

    Another thing is weird. When I began TRT 3 years ago or so I had acne on my back and some on face. It lasted so long I was ready to give up. It wasn't terrible but what 40 year old man wants bacne? I switched to Actavis and this never happened again. Even when I restarted TRT after and 8...

    Primo for estrogen management!

    I don't know. I would never use a compound er again if I didn't have to. I used four different ones not my choice. My clinic just would.randomly send. Once vial crashed repeatedly and another my numbers were 200 points lower. Actavis from pharma has been perfect since.

    Primo for estrogen management!

    I wouldn't get too overconfident on this. I understand UGL for + products on TRT and sure many of these UGL labs have vials sent to Jano but there is zero chance you will convince me that the ingredients and process of any UGL compares to Western Pharmaceutical standards. I may be wrong but I...

    Primo for estrogen management!

    It's the primo. I once was using 120mg of Test cyp per week with 2 amps of Bayer Rimobolan (250mg of primo) and my total test was 512 and my free T was 31 E2 of 4. On test cyp at 160mg per week I am 1000 and 35 and E2 30-40. Primo is a wild drug. The "golden" ratio from my experiments is 2:1...

    Deca (nandrolone) for joint pain

    I have arthritis in my neck to the point where I need chiropractic care weekly and torn TFCC cartilage in both wrists. I have used Deca as an adjunct to TRT up to 200mg per week and never noticed joint relief. I personally think it is a scam to sell TRT+. It is quite anabolic though I will...

    looking for success stories on individuals who conceived while on trt

    You can get Pregnyl 10,000 with a goodrx coupon for roughly 110-120$. This is how I get my HCG.

    looking for success stories on individuals who conceived while on trt

    Have you had a semen analysis done? They a few hundred $ and you don't need a prescription to do this. Also, who is prescribing your testosterone? I find it a bit shocking that same provider wouldn't prescribe HCG. Are you handling your own TRT w/o a doc? No judgements just curious about...

    looking for success stories on individuals who conceived while on trt

    If you want it to happen quickly you should come off TRT. I did it this way and my wife was pregnant as soon as it was possible. 5 months from my last shot. It's your best sure shot. Get a semen analysis to see where you are. Dr Rand has been quoted as advising what the above poster has...

    Melatonin Preventing Estrogen-Mediated Gene Transcription In Vitro

    Why would they would need this if they were taking tamoxifen or anastrazole? As for the OP quote on DHT derivatives, I use primobolan from time to time and it crushed my E2 bloodwork confirmed. As in nearly non-existent.

    Why does 100mg oral pregnenolone spike my libido beyond belief?

    I wonder what the half life of this Pregnenolone is... at 10 days you are most certainly already there.

    Why does 100mg oral pregnenolone spike my libido beyond belief?

    I hate to say it but I am willing to bet that so many of us have been thru this before when adding a compound and then we think we have it figured out and then all of the sudden poof we lost what we were chasing. Its probably either in your head (placebo) effect I mean you have perfect hormones...

    What does low shbg actually mean ?

    Your numbers are absolutely perfect IMO it should be working for you. Your numbers are very similar to mine although I use a bit more test 80mg E3.5D and sit around 1000ng/dl with the same E2 and SHBG levels. I find if I deviate from this everything goes to shit but I can always come back to...

    Has anyone had any really bad sides with PT-141?

    The flushing went away in about an hour... no nausea. Haven't noticed anything else and it has been about 10 hours. Are you guys dosing this daily or every 3 days while getting to the "working dose"?

    Has anyone had any really bad sides with PT-141?

    Ok so now all of these bright red bumps are crazy showing across my arms and back... they barely show usually . This is totally bizzarre but I guess the flushing side effect is real for me.

    Has anyone had any really bad sides with PT-141?

    Either I had too much coffee or something happened bc I am bright red from the neck up about 10 minutes after this shot.

    Has anyone had any really bad sides with PT-141?

    Ok. Thanks for the feedback. I started today with 125mcg. Will let you know how it goes. It's literally amazing how chicken shit I am to inject this stuff. 15 years ago I would inject UGL steroids nearly year round and I'm having trouble injecting 125mcg of a research peptide. How pathetic.

    Has anyone had any really bad sides with PT-141?

    I understand how to reconstitute and measure this for sure. The vial is in milligrams (10) to be exact. So I was wondering what dilution ratio you are using. 1ML would imply what you are suggesting.

    I can’t find HCG/Pregnyl

    Vigorous Steve said 28 days due to the NaCl in the Pregnyl solvent. He's completely wrong on that because the insert from the manufacturer says the solution is STABLE 60 days using the same solvent. That guy is all over the place. First it was HCG stopped working due to LH downregulation and...

    Has anyone had any really bad sides with PT-141?

    I got a 10mg bottle of PT-141 from Peptide Sciences. Wanted to run an experiment to see if it works... 1mg and then if nothing happens go to 2 and then if nothing happens, trash the bottle. I can't pull the trigger as I have been reading about some really bad cases of nausea. Has anyone had...

    I can’t find HCG/Pregnyl

    Right, I'm saying its at LEAST 60 days refrigerated, probably much longer, and probably even without refrigeration.

    I can’t find HCG/Pregnyl

    This is interesting bc I have had old vials of pregnyl that I tossed into the syringe box that still had some liquid. No refrigeration for weeks on end and mixed months and months back and they still showed up positive on pregnancy tests. Just an experiment I ran once. I'd be willing to bet...

    Started DHEA + Preg 25/10 and sleeping like a rock?

    There was a guy who said once on this board "once you think you have things figured out, they change" and it is kind of maddening.

    Started DHEA + Preg 25/10 and sleeping like a rock?

    I have to say this only lasted a week sadly. I thought deeply about it and recalled that during the week that I slept like a rock and began supplementing these, I took off from the gym for 3-4 days in a row. I must have been overtrained and it was affecting my sleep in a negative way. That's...

    Urologist suggest correlation between hematocrit and T....but none exist in my medical history.

    When I stopped TRT for 8 months my hematocrit dropped to 39. Within 8 weeks of resuming TRT at 80mg E3.5D it was back to 48.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
