Research Pens

Pen Lasts

20 doses per pen (~20 days at 1x daily). Well within the 28-day stability window.

Pen Lasts

40 doses per pen at 5 nights/week — roughly 8 weeks per pen. Refrigerated peptides stay usable well past 28 days; potency drifts down only slightly per week, so most research users run the full pen without a noticeable difference.

Pen Lasts

20 doses per pen (~20 days at 1x daily). Remake every 20 days across the full cycle.

Pen Lasts

20 doses per pen (~20 days at 1x daily). Comfortably covers a 4-6 week on-cycle across 2 pens.

Pen Lasts

24 doses per pen at 5x weekly — roughly 5 weeks per pen. Kept refrigerated, the pen stays usable beyond 28 days with only a minor, gradual dip in potency week to week — not enough to notice in practice.

Pen Lasts

Loading phase: pen empties in ~10 days (2x daily draws). Maintenance phase: ~40 doses (~40 days). Refrigerated, potency declines only slightly each week beyond 28 days — most people run the full pen without noticing a difference.

Pen Lasts

20 doses per pen (~20 days at 1x daily). Remake every 20 days across the cycle.

Pen Lasts

20 doses per pen — a near-perfect fit for the standard 20-day-on cycle in one pen.

Pen Lasts

20 doses per pen (~20 days), matching the 10-20 day on-cycle with room to spare.

Pen Lasts

High-consumption pen: ~2.5 days at the week-1 starting dose, dropping to ~1.25 days at the 40mg/day trial dose. Expect to order several pens per week at trial dosing.

Pen Lasts

4 doses per pen at 2-3x weekly (~11-16 days). Well within the 28-day stability window.

Pen Lasts

Consumed asymmetrically between the daily BPC-157 draw and the twice-weekly Thymosin Alpha-1 draw — pen empties in ~14 days. Well within stability.

Pen Lasts

25 doses per pen (~25 days at 1x daily). Covers the full cycle with a pen to spare.

Pen Lasts

50 doses per pen at 1x daily — roughly 50 days. One pen comfortably covers a full 4-6 week cycle; refrigerated, any potency drop beyond 28 days is gradual and minor, not something you'd notice week to week.

Pen Lasts

20 doses per pen at an average 2x daily — roughly 10 days per pen on a 2-4 week protocol.

Pen Lasts

20 doses per pen (~20 days at 1x daily). Remake every 20 days across the 12-week cycle.

Pen Lasts

2 standard doses per pen at 1x weekly (~14 days). Order 2 pens per month at standard dosing.

Pen Lasts

Roughly 6 doses per pen at the standard 40-unit draw — about 3-4 weeks between refills at typical on-demand use (up to 8x/month).

Pen Lasts

Loading phase: pen empties in ~10 days (2x daily draws). Maintenance phase: ~40 doses (~40 days). Refrigerated, potency declines only slightly each week beyond 28 days — most people run the full pen without noticing a difference.

Pen Lasts

One 3.0ml pen covers roughly the first 4 weeks of the titration schedule (2mg→9mg) before a refill is needed as the weekly dose escalates.

Pen Lasts

High-consumption pen: the 5-7 day loading phase alone (150mg/day) can exceed one pen — budget 2 pens to complete loading, then ~14 days per pen at maintenance dosing.

Pen Lasts

20 doses per pen (~20 days at 1x daily). Matches the 8-12 week on-cycle with pens to spare.

Pen Lasts

~24 doses per pen (~24 days at the phased 10-15 unit draws). Comfortably covers each phase of the protocol.
