Triptorelin protocol

PCT

PCT restart

10u

100 mcg · Single dose

One SubQ injection in the early phase of PCT, after clearance of long-ester steroids. Do NOT repeat, repeated dosing suppresses the axis.

PCT restart	Single dose	100 mcg	10u	One SubQ injection in the early phase of PCT, after clearance of long-ester steroids. Do NOT repeat, repeated dosing suppresses the axis.

Units column is at 1 mg/mL. Critical: the value is in a single low dose to trigger the LH/FSH flare. Repeated or higher dosing flips it into suppression (its clinical use). Timing relative to ester clearance and the rest of a PCT (often with SERMs) matters, this is not a casual peptide.

Cycle & timing

Cycle: Single dose per PCT; do NOT repeat.

Timing: Early phase of PCT, after clearance of long-ester steroids.

Where: SubQ, abdomen.

What to expect

A jump in LH/FSH and testosterone over the days following the single shot, supporting natural-production recovery as part of a complete PCT.

How much to buy

For single-dose-per-PCT use:

1 vial (covers ~20 single 100 mcg doses)

× 2mg vials

Men & women

Men: Used post-cycle to restart the testosterone axis (a single low dose flares LH).

Women: Cycle-timed, ovulation trigger, IVF prep, endometriosis. A single dose flares then suppresses.

Stop if you notice

This is a single-dose tool, do not re-dose chasing an effect
Severe mood disturbance during the flare
Any signs of a hormone-sensitive condition worsening

Side effects

Initial flare symptoms (mood, libido swings), headache, injection-site reaction. Wrong dosing can worsen suppression.

Drug interactions

Other hormonal agents (SERMs, HCG, AIs): part of structured PCT; sequence and timing matter. Drugs that prolong QT: caution (class effect).

Labs

LH, FSH, total/free testosterone, estradiol (baseline + during recovery). Confirm steroid esters have cleared before use. Out of range? Low testosterone / low LH-FSH during recovery = the axis hasn't restarted yet, give it time or adjust.

What these labs mean →

Warnings

Single-dose-only for the flare effect, repeated dosing suppresses the axis (the opposite of the intended PCT effect). Initial testosterone/estrogen flare can transiently worsen hormone-sensitive conditions. Mood and libido fluctuation during the flare. Improper PCT timing can prolong low-testosterone recovery.

Patient education

One shot, not a course; re-dosing backfires into suppression. Only meaningful as part of a properly timed PCT. Get labs to confirm recovery rather than guessing. Not for use by women of reproductive age or in pregnancy.

These apply on top of the universal safety rules.

Can Triptorelin + HCG share a syringe?

Depends on timing. Reproductive and hormonal peptides are compatible, but doses and timing vary widely. Combine only what you truly co-time. If unsure, separate.

What it does

Powerful and long-lasting, easy to get wrong, so it’s a careful-use compound. Used clinically (repeated/continuous dosing) for prostate cancer/endometriosis.

Triptorelin is a synthetic GnRH (gonadotropin-releasing hormone) agonist. A single dose causes an initial surge (“flare”) of LH/FSH and testosterone, used in PCT to restart the HPTA. (Paradoxically, repeated/continuous dosing downregulates GnRH receptors and suppresses the axis; which is how it’s used clinically for prostate cancer/endometriosis.) Dose and timing matter enormously.
