Thread: Atrophy on HCG

Okay so this is kinda weird. Just started a new cycle:

1-16 Test E 750mg
1-14 EQ 600mg
1-4 Test P 300mg
4-8 Dbol 50mg

I decided to try some HCG this time since everyone is all about it. I got this stuff in a clear vial with blue chinese all over it and a blue dot on the neck. 5000iu's. I have 4 of them just in case.

I started the HCG on week 2. Currently in week 3 of this (And up 12lbs ). I did 2 shots of 250iu last week. I did it this way to see how I responded. The first night I remember waking up and it felt like I had blue balls. It was weird. When I woke in the morning all was fine. Haven't felt this since. Maybe it was just in my mind.

The problem is I'm still getting some atrophy. Is this normal? I planned on running 250iu 2x/wk throughout the cycle but I'm not so sure anymore. This morning I woke up and did a 500iu shot. I'm doing these Sub-q if it matters.

This study demonstrates that around 300iu HCG every other day is needed to raise ITT levels to baseline while administering Testosterone. That's 1,050iu HCG weekly.

In previous studies of testicular biopsy tissue from healthy men, intratesticular testosterone (ITT) has been shown to be much higher than serum testosterone (T), suggesting that high ITT is needed relative to serum T for normal spermatogenesis in men. However, the quantitative relationship between ITT and spermatogenesis is not known. To begin to address this issue experimentally, we determined the dose-response relationship between human chorionic gonadotropin (hCG) and ITT to ascertain the minimum dose needed to maintain ITT in the normal range. Twenty-nine men with normal reproductive physiology were randomized to receive 200 mg T enanthate weekly in combination with either saline placebo or 125, 250, or 500 IU hCG every other day for 3 wk. ITT was assessed in testicular fluid obtained by percutaneous fine needle aspiration at baseline and at the end of treatment. Baseline serum T (14.1 nmol/liter) was 1.2% of ITT (1174 nmol/liter). LH and FSH were profoundly suppressed to 5% and 3% of baseline, respectively, and ITT was suppressed by 94% (1234 to 72 nmol/liter) in the T enanthate/placebo group. ITT increased linearly with increasing hCG dose (P < 0.001). Posttreatment ITT was 25% less than baseline in the 125 IU hCG group, 7% less than baseline in the 250 IU hCG group, and 26% greater than baseline in the 500 IU hCG group. These results demonstrate that relatively low dose hCG maintains ITT within the normal range in healthy men with gonadotropin suppression. Extensions of this study will allow determination of the ITT concentration threshold required to maintain spermatogenesis in man.
