- 0:00Everyone knows HEGs use for fertility and to re-signal the LH receptor, but most people
- 0:04don't know how to get the most out of this compound. So obviously, HEG is going to mimic
- 0:08LH and right when you hop on a cycle, your LH and your FSH get suppressed, obviously,
- 0:11just as your natural production does. So if you wanted to maintain fertility from the
- 0:14beginning of your cycle, you would also want to implement HEG at the beginning of your cycle,
- 0:18starting at a dose of 250 all the way to 500 I use twice a week. Now the critical rule most
- 0:22people get wrong when running this compound is they don't stop it, you know, four to five days
- 0:26before their PCT. And then when they do start their, you know, serum that like Encholmophine or
- 0:30Novodex, it's not able to take full effect because the HEG is still in their system. You need to
- 0:35understand that HEG is still mildly suppressive on its own and the serum is not going to be able
- 0:39to work correctly if it's not fully out of your bloodstream. And also HEG does not restore
- 0:43HPTH to the brain. So it's not going to re-signal your natural production to start up again. So
- 0:47although this is going to help you with fertility, you can run it during a cycle to, you know,
- 0:51help re-signal LH, but after cycle you do need to stop it before doing your serum and
- 0:56also you do need to do the serum 100% because like we said, this is not going to work as a PCT.
- 1:01All it is going to do is help restore or maintain fertility while on cycle. So hope that helps.
HCG and fertility on TRT: what the evidence actually supports
Quick answer
HCG (human chorionic gonadotropin) is used clinically to preserve intratesticular testosterone production and spermatogenesis in men on exogenous androgen therapy, acting as an LH analog at the Leydig cell without restoring hypothalamic-pituitary signaling. The creator's advice to discontinue HCG before initiating SERM-based post-cycle therapy reflects a recognized concern about HCG's suppressive LH-receptor activity competing with SERM-mediated endogenous LH stimulation, though the four-to-five day clearance window cited is shorter than HCG's pharmacokinetic profile typically supports. Men using anabolic steroids outside of physician supervision who attempt this protocol have no clinical safeguards for monitoring axis recovery or sperm parameters.

Page-specific review note
What this exact clip is really saying
This FormBlends review is specific to "HCG and fertility on TRT: what the evidence actually supports" from Avery Fisk. We read the clip as a TRT social video fact-checks claim about Testosterone, then separate the useful signal from what a short social video cannot prove. The page-specific claim focus is: HCG (human chorionic gonadotropin) is used clinically to preserve intratesticular testosterone production and spermatogenesis in men on exogenous androgen therapy, acting as an LH analog at the Leydig cell without restoring hypothalamic-pituitary signaling.
The reason this review is not generic is the source wording and the canonical claim label "trt if you care about fertility this could be essential to add i." In this clip, the useful excerpt is: "Everyone knows HEGs use for fertility and to re-signal the LH receptor, but most people don't know how to get the most out of this compound." That wording changes the review because it points to Testosterone evidence, safety, and patient-fit context, not a one-size-fits-all protocol.
The source trail for this page is checked against Cardiovascular Safety of Testosterone-Replacement Therapy (2023), Testosterone therapy in men with androgen deficiency syndromes: an Endocrine Society clinical practice guideline (2010), and Functional testosterone deficiency in aging men: Clinical impact, diagnostic pathways, and treatment strategies (2026), plus the creator's own wording. Testosterone decisions still need an eligibility review, medication-interaction screen, access check, and quality-control review before anyone treats a social clip as medical advice.

Use the clip as a claim to verify, not a treatment plan
What it helps with
- HCG (human chorionic gonadotropin) is used clinically to preserve intratesticular testosterone production and spermatogenesis in men on exogenous androgen therapy, acting as an LH analog at the Leydig cell without restoring hypothalamic-pituitary signaling. The creator's advice to discontinue HCG before initiating SERM-based post-cycle therapy reflects a recognized concern about HCG's suppressive LH-receptor activity competing with SERM-mediated endogenous LH stimulation, though the four-to-five day clearance window cited is shorter than HCG's pharmacokinetic profile typically supports. Men using anabolic steroids outside of physician supervision who attempt this protocol have no clinical safeguards for monitoring axis recovery or sperm parameters.
- HCG acts on Leydig cells as an LH analog, not on the hypothalamus or pituitary, so it preserves testicular function without restoring the HPG axis. This distinction is clinically important and the creator got it right.
- HCG's half-life is approximately 36 hours, meaning full pharmacokinetic clearance takes closer to 7-10 days, not the four to five days cited in the video. Timing PCT entry based on a shorter window may leave residual receptor activity.
What it may miss
- It may not cover eligibility, contraindications, medication interactions, lab history, or dose escalation.
- Compound access, legal status, and product quality still need a separate safety check.
- Social video captions rarely show the full evidence base behind a claim.
Best next step
Compare the claim against a FormBlends guide, safety page, and licensed-provider review before acting.

Our take · Written by FormBlends editorial team · Reviewed by FormBlends Medical Team · This is not a transcript. It is our independent review of the video above.
What did @averyfisk_ actually say?
The creator laid out a protocol for using HCG (which they call "HEG" throughout) during an anabolic steroid cycle to preserve fertility. The core advice: start HCG at 250-500 IU twice weekly from the beginning of a cycle, stop it four to five days before starting PCT, and then run a SERM like clomiphene or tamoxifen ("Novodex") for post-cycle therapy. They also stated plainly that HCG "does not restore HPTH to the brain" and cannot serve as a standalone PCT.
The framing is aimed at bodybuilders running their "first cycle," which matters because this is a younger, likely self-medicating audience making decisions without physician oversight. That context shapes how seriously we need to evaluate the accuracy here.
Does the science back this up?
Mostly, yes, with some real caveats worth unpacking. HCG does mimic LH at the Leydig cell level, and using it during suppression to maintain testicular function and sperm production is well-supported. The concern about HCG's residual activity interfering with SERM-driven HPG axis recovery is biologically plausible and echoed in clinical practice, though the exact timing window isn't as clean as "four to five days."
A 2013 review by Shoshany et al. in Fertility and Sterility confirmed that exogenous gonadotropins including HCG can maintain intratesticular testosterone and spermatogenesis during androgen-induced suppression. The claim that HCG bypasses hypothalamic-pituitary signaling is accurate: it acts downstream at the gonad, not at GnRH or LH pulse generation. Coviello et al. (2004, Journal of Clinical Endocrinology and Metabolism) demonstrated this distinction clearly in men on exogenous testosterone.
What did they get wrong (or right)?
They got the core biology right. HCG does mimic LH. It does not restore the hypothalamic-pituitary axis. It is mildly suppressive on its own, which is an underappreciated point that the creator deserves credit for raising.
What's murkier: the "four to five days" stoppage window before PCT. HCG has a half-life of roughly 36 hours, meaning it takes closer to 7-10 days to clear meaningfully from the system. Stopping four to five days out and immediately starting a SERM may not give adequate clearance. Ramasamy et al. (2014, Journal of Urology) suggest that timing protocols in fertility recovery need to account for individual clearance variability, not just a fixed window.
The creator also consistently says "HPTH" when they clearly mean the HPG axis (hypothalamic-pituitary-gonadal axis). This isn't a minor slip. If someone new to this topic hears "HPTH" and tries to research it, they'll find nothing useful. The repeated mispronunciation of the acronym and of drug names ("Encholmophine" for clomiphene) suggests a level of familiarity that falls short of what's being presented as expertise.
What should you actually know?
HCG use during anabolic steroid cycles to preserve testicular volume and fertility potential is a legitimate clinical strategy. It is used in supervised testosterone replacement settings for men who want to maintain fertility. But the dosing ranges the creator mentions are not universally agreed upon, and self-administering HCG without monitoring hormone levels and sperm parameters is flying blind.
Anyone serious about fertility preservation on cycle should be working with a urologist or reproductive endocrinologist, not optimizing a protocol from TikTok. PCT with SERMs after unsupervised steroid use carries real risks including mood instability, vision changes with tamoxifen, and incomplete axis recovery. The creator is right that HCG alone is not sufficient for PCT, but "run it and then do your serum" is not a substitute for clinical guidance.
- HCG half-life is approximately 36 hours; plan clearance timing accordingly, not on a four to five day assumption.
- The HPG axis, not "HPTH," is the correct terminology for what this protocol is attempting to protect.
- Fertility preservation on cycle requires baseline and follow-up semen analysis to know if it's working.

Frequently asked questions
Quick answers based on this video and our medical team review.
What does the video say about hcg acts on leydig cells as an lh analog, not?
HCG acts on Leydig cells as an LH analog, not on the hypothalamus or pituitary, so it preserves testicular function without restoring the HPG axis. This distinction is clinically important and the creator got it right.
What does the video say about hcg's half-life?
HCG's half-life is approximately 36 hours, meaning full pharmacokinetic clearance takes closer to 7-10 days, not the four to five days cited in the video. Timing PCT entry based on a shorter window may leave residual receptor activity.
What does the video say about coviello et al. (2004, jcem) showed?
Coviello et al. (2004, JCEM) showed that HCG co-administration during testosterone therapy maintains intratesticular testosterone at levels sufficient to support spermatogenesis, validating the on-cycle fertility rationale.
What does the video say about hcg downregulates lh receptor sensitivity with prolonged use?
HCG downregulates LH receptor sensitivity with prolonged use and elevates estradiol via aromatization of the testosterone it stimulates. Neither effect is discussed in the video, and both matter for cycle management.
What does the video say about the creator repeatedly uses the term 'hpth' instead of hpg?
The creator repeatedly uses the term 'HPTH' instead of HPG axis and mispronounces clomiphene. These errors matter because viewers researching these terms will not find accurate supporting information.
What does the video say about anyone using hcg for fertility preservation during?
Anyone using HCG for fertility preservation during or after anabolic steroid use should have baseline and follow-up semen analyses performed. Without sperm count data, there is no way to confirm the protocol is working.
