Return Peptide Stack
A phased protocol for men on testosterone replacement who want their natural production — and fertility — back. Kisspeptin restarts hypothalamic signalling; HCG bridges testicular function; BPC-157 + Selank hold the recovery environment. Best run alongside a physician-prescribed SERM, with supervision and bloodwork.
What's in this stack
Kisspeptin is a peptide that influences the reproductive hormone pathway, often studied for its role in modulating hormone release in the body.
Human chorionic gonadotropin is an injectable peptide hormone used to support natural testosterone synthesis and reproductive health when hormone levels are suppressed during cycles.
BPC-157 is a synthetic peptide modeled after a fragment of human gastric juice, studied for its potential to support tissue repair and recovery.
Selank is a laboratory‑made peptide that acts as a cognitive enhancer, helping to lessen anxiety and promote a more balanced mood.
Who this stack is for
Men on testosterone replacement therapy who want their natural production and fertility back — whether for family planning, freedom from the compound cascade (HCG + AI + cabergoline + tadalafil), side-effect fatigue, or an age-appropriate transition to sustainability. Not for genuine primary hypogonadism, post-orchiectomy, or long-term high-dose users with severe testicular atrophy shown on imaging.
How to run it
Four phases over 6–12 months, with physician supervision and bloodwork throughout. Phase 1 (weeks 1–2): reduce TRT, prime the hypothalamus with Kisspeptin, correct cofactors. Phase 2 (weeks 3–6): stop TRT completely, add a physician-prescribed SERM (such as clomid, nolvadex, or enclomiphene — sourced through your doctor) to block estrogen feedback and accelerate GnRH restart, while HCG bridges testicular function. Phase 3 (weeks 7–16): drop HCG to force testicular response to natural LH, taper the SERM. Phase 4 (months 4–12): SERM removed, living on your own production with cycled Kisspeptin and cofactor support. The peptide + HCG side of this protocol is what Aevum maps; the SERM itself is a prescription item you obtain and dose under medical guidance.
What to expect
Honest truth: this is harder than starting TRT. Weeks 3–8 are the hard part — fatigue, low libido, mood dips, temporary muscle loss while the body is between exogenous support and restored production (Selank helps the psychological weight). Weeks 9–16: energy and libido recover, LH/FSH normalise, testosterone climbs. Months 4–12: body composition stabilises at natural baseline, sleep often exceeds TRT, autonomy restored. Men who used TRT under ~2 years typically restore full function; 5+ years or high-dose without HCG may have permanent HPG dysfunction — this protocol maximises recovery but cannot guarantee it.
Frequently asked questions
Can you actually come off TRT and restore natural testosterone?
For men whose TRT was started for age-related decline, lifestyle, or aesthetics, natural recovery is typically achievable with commitment. The HPG axis has memory: Kisspeptin + a SERM restart hypothalamic and pituitary signalling, HCG bridges testicular function, and over 6–12 months production can restart. Under ~2 years of use restores most reliably; 5+ years or high-dose without HCG carries risk of permanent dysfunction.
How long does TRT recovery take?
Complete HPG axis restoration and stable natural testosterone typically takes 6–12 months. LH/FSH normalise around weeks 4–8 with SERM support; testicular response and sperm production (FSH-dependent) restore over 6–18 months. Rushing reduces success — patience is the primary requirement.
Do I need a doctor for the Return protocol?
Yes. This protocol involves SERM prescriptions and ongoing bloodwork monitoring (baseline, weeks 4/8/16, months 6/12). Work with a physician who understands hormonal recovery, not just a peptide vendor. Aevum provides the informational protocol and supply chain; it is not medical advice.
